1. Tendons attatched to bone is composed of thick, closely packed bundles
of collagen fibrils oriented parallel to the long axis of the tendons. 2.The thick
bands are the protein collagen while the thin dark threads are the protein
elastic. 3. The fibers of areolar connective tissue are arranged in no
particular pattern but run in all directions and form a loose network in the
intercellular material. 4.It consist of fibroblast, collagen fiber, elastic fiber and
macrophage 5. This image is labeled with fibroblast, collagen fiber,
macrophage and elastic fiber

1. Adipose taken from the umbilical cord. 2. The edge of the cell have
nucleus which is dark purple, adipose cell is white and around the lined light
purple is cytoplasmic membrane. 3. This image shows anterior adipocyte of
the belly. 4. This is a histological section of mammary tissue from a
nonpregnant woman: Label A = adipose tissue; C = connective tissue
sheaths running through the adipose tissue; D - ducts growing. 5. This
image shows the arrow pointing to macrophage (blue), nucleus (purple),
annd the large pointer in adipocyteup through the connective tissue sheaths.
NA
1. A network of interlacing reticular fiber in dark purple and reticular cell in
light purple. 2. This consists of reticular fibers and reticular cells interlaced
to form a lose network that helps give structure to organs. The black reticular
fibers located between reticular cells. 3. The cells that make the reticular
fibers are fibroblasts called reticular cells. 4. The reticular fibers are attached
to the reticular cells, so the two components of reticular connective tissue
are "fixed", they cannot move around. The other cells and tissue fluid can
move around in the spaces between the reticular fibers. 5. The red arrows
point to individual reticular fibers. The dark-colored dots scattered among the
fibers are mostly reticular cells and lymphocytes.

1. Consists of chondrocytes located in a threadlike network of elastic fibers
within the extracellular matrix. 2. Elastic cartilage
Lacunae containing the chondrocytes, which are characteristic of cartilage,
are embedded in a matrix with elastic fibers. The fibers are dark pink. 3. The
stain for elastin that brings out the dense bundles. 4. Elastic cartilage is
flexible. It is found in the epiglottis, pinna of the ear, auditory tube and
eustachian tube. It is organized in a similar way to hyaline cartilage with a
perichondrium and chondroblasts and chondrocytes embedded in a matrix.
The major difference is in the matrix where branched elastin fibres are
present in addition to collagen
NA
1. The lacunae are not as numerous in this cartilage and they are smaller.
the nuclei of the chondrocytes is a red-purple color. 2. This image shows
the fibrocartilage from an intervertebral disk. It is distinguished by very
scattered, infrequent chondrocytes in dark cuclei collagen fibers running in
the matrix. 3. In fibrocartilage the structure is intermediate between that of
hyaline cartilage and dense connective tissue. It is found where bones are
bound together such as at the pubic symphysis and as part of intervertebral
discs. The cells are squeezed into rows by thick bundles of collagen fibres
in the matrix. The collagen is orientated in the direction of stress. The gel
component of the matrix is reduced compared to hyaline cartilage. 4. Here is
tighter fibrocartilage from a pubic symphysis.
NA
1. There are two osteons in this micrograph. The dark and light ovals are the
central canals or Haversian canals through which blood vessels and nerves
project. Surrounding central canals are the lamellae with the osteocytes
embedded in the solid calcium and phosphate matrix. The fine lines
radiating out from the center are canaliculi. 2. This shows the architecture of
compact bone which is designed to nourish and regulate osteocytes and
bone matrix. 3. The osteon is labaled from inner to outer of haversion canal,
lamella, canaliculi and lacuna. 4. The concentric layers of mineralized
matrix called lamellae (Lm), surround the Haversian canal (Hc). Concentric
arrays of almond-shaped lacunae (Lc) containing osteocytes are visible.
Radiating from the Haversian canal in all directions are spaces or fine tubes
called canaliculi (Cl).
NA
Sponge is made of bone or Trabeculae -{1} and the air is made of red bone
marrow -{3}; the marrow produces red blood cells, cancellous cavities which
contain Osteoblasts -{2}, The trabeculae are surrounded by a layer called
the Periosteum marked as {4}. 2. An electron micrograph scan of spongy
bone in an osteoporosis patient. Osteoporosis occurs when a body's blood
calcium level is low and calcium from bones is dissolved into the blood to
maintain a proper balance. 3. Cancellous bone showing its bony trabeculae
(pink) and marrow tissue (blue). 4. It contains large marrow spaces defined
by shelves and spicules of bone. The inner space is lined by osteoblasts
and osteoclasts.
NA
1. Human red blood cells in red from a leg wound. 2. Red Blood cell(RBC)
also referred to as erythrocytes are the most common type of blood cell.
This scanning electron micrograph that have been magnified a little over
11,000 times. Being biconcave in shape allow RBCs to have a greater
surface area and carry more oxygen through your body. 3. Red blood cells
(erythrocytes) trapped in a mesh of fibrin threads. Fibrin, a tough, insoluble
protein formed after injury to the blood vessels, is an essential component of
blood clots. 4. Ideal blood smear with neutrophil, lymphocyte and platelets.
Basophil
1. This type of WBC secrete heparin and histamine. Heparin keeps from
clotting and histamine stimulates inflammation. 2. Bluish lack granules of
univorm size within the cytoplasm and typically a bilobate nucleus. 3. Mast
cell and basophil labeled. 4. Basophils constitue .5 to 3% of peripheral blood
that release histamine and serotonin.
Eosiniphil
1. Eosinophils, platelets and RBC is labeled on this image. 2. Eosinophils-10 to 15 um diameter and constitute 2.0 to 4.0% of leukocytes. 3. These
cells usually contain a bilobate (two lobes) nucleus and a cytoplasm full of
brightly stained eosinophilic (orange-red) specific granules. 4. Eosinophils
function specifically as phagocytes to destroy larvae of parasites that have
invaded tissues in trichinosis, schistosomiasis, and appear to play a role in
allergic responses. Other functions of eosinophils include phagocytosis of
antigen antibody complexes.
Neutrophil
1. The size of Neutrophil are 10 to 15 u diameter. 2. These cells constitute
70% of leukocytes and usually have 2 to 5 nuclear lobes connected by fine
filaments of chromatin. Neutrophils are the most numerous of all leukocytes,
3. The cytoplasm is pink to grey because of the neutral staining of specific
granules (i.e. they don't stain). 4. Neutrophils function as scavengers within
extravascular tissue, destroying bacteria or other infectious organisms that
invade the body. Neutrophils are also called Polymorphonuclear Leukocytes
(PMNs) in some laboratories even though the following two cell types also
have multi-lobed nuclei.
Lymphocyte
1. T lymphocytes in green are involved in the specific immune response and
are composed mainly of precursor T cells and B cells. 2. Subsets of
lymphocytes that originated in the red bone marrow from hematopoietic
stem cells 3. Lymphocytes - 9 to 14 um diameter
Lymphocytes constitute 20 - 25% of agranulocytes and may be small,
medium or large in size. 4. The nucleus is rounded or oval, and usually the
same size as an erythrocyte. The chromatin is densely packed with no
apparent nucleoli. When compared with nuclei of other cells, the lymphocyte
nucleus almost always appears smudged. 5. Stained blood smears you are
using. Some lymphocytes migrate into the connective tissues and become
Plasma Cells.
Monocyte
1. Monocytes - 12 to 20 um diameter, and comprise 3 - 8% of
agranulocytes. 2. This large cell has a lightly stained nucleus that often
appears horseshoe or kidney shaped. 3. The chromatin appears lacy and
nucleoli are usually not apparent. 4. The abundant cytoplasm stain quite
often contains vacuoles small, clear areas.
Macrophage
1. Tissue in purple/pink is a mature phagocyte that can ingest invading
microbes, foreign particle and cellular debris. 2. Cell is seeking foreign
bacteria(Escherichia coli) with specialized cell extensions called filopodia 3.
This image is labeled with the ferritin particles in phagocytic vacuoles. 4.
This low magnification image from the human umbilical cord shows the
characteristic appearance of mucous connective tissue: sparsely scattered
cells; sinuous collagen fibers; and lots of ground substance, which is
unstained. About half of the nuclei seen belong to fibroblasts and the other
half to macrophages, although it is usually not possible to tell them apart.

They are irregular shaped, colourless bodies that are within our blood. The
surface is sticky and with other substances, form clots to stop bleeding. The
platelets gather at the wound and attempt to block the flow of blood.3.
Human Red Blood Cells, Platelets and T-lymphocyte(erythocytes = red;
platelets = yellow; T-lymphocyte = light green) 4. The average lifespan of a
platelet is between 8 and 12 days. Platelets play a fundamental role in
hemostasis and are a natural source of growth factors
Plasma
1. Blood is a connective tissue consisting of cells suspended in an
intercellular fluid (the blood plasma). 2.Blood functions to transport oxygen,
carbon dioxide, nutrients, wastes, hormones, etc. to and from the body's
cells. Blood cells consist of erythrocytes (red blood cells), leukocytes (white
blood cells) and thrombocytes (platelets). 3.The above picture is a smear of
human peripheral blood. 4. Final histological examination showed diffuse
infiltration of mature and immature plasma cells in thyroid
Lymph
1. Lymph nodules are unencapsulated lymphoid tissue located in several
organs of the digestive and respiratory tracts, and all organs of the lymphatic
system. They are composer of densely packed lymphocytes (mainly Blymphocytes) that differentiate into plasma cells after appropriate antigenic
stimulation. Secondary lymph nodules exhibit a pale staining germinal
center, indicating that an antibody response to an antigen is occurring.
Primary lymph nodules have not been activated, therefore, lack germinal
centers. Peyer's patches are aggregates of unencapsulated nodules found in
the lamina propria of the ileum. 2. Lymph nodes are spherical or kidneyshaped organs that are distributed throughout the body. The node is
enclosed by a connective tissue capsule from which large connective tissue
trabeculae arise and subdivide the underlying parenchyma. Each lymph

Muscle
Nervous
Skeletal
1. This skeletal muscle cross section is preserved with a collagen stain to
bring out the perimysium between the fascicles. Each muscle is composed
of thousands of fibers (E), each with a covering of loose connective
tissue—endomysium (B). The fibers are organized in parallel bundles called
fascicles (D). Each fascicle is surrounded by a perimysium sheath (A); the
presence of collagen bundles suggests dense connective tissue. Multiple
fascicles are encased in a dense connective tissue—epimysium, which
covers the entire muscle organ. Blood vessels, like the one shown at (C),
and nerve fibers penetrate to the endomysium to supply the muscle fibers.
3. Longitudinal section of skeletal muscle: The individual muscle fiber (C)
originates from a fused series (syncytium) of myoblasts surrounded by a
common sarcolemma. Because of this, multiple nuclei (B) are found within
Smooth
1. Spindle shaped, thickest in the middle and tapering at both ends, non
striated fibers with one nucleus. 2. Long, slender central nuclei, lying within
narrow, fusiform cells that lie parallel to each other in a smooth arrangement.
3. Cells more separated so as to see their extent and shape better, and the
central position of their nuclei. A loose, irregular connective tissue
(endomysium) lies between the cells. Nuclei seen in this picture belong to
fibroblasts mainly. 4. Smooth muscle with wrinkled nuclei due to contraction
of cells.
Cardiac
1. Stem cells placed in the heart have morphed into cardiac muscle cells. 2.
Heart muscle with purkinje fibers(green) on the surface, which originated
from the atrioventricular node and spread into the two ventricles. 3. Branched

finer astrocytic processes. 3. This is an example of an anaplastic
astrocytoma. 4.Cell bodies of astrocytes are among the largest for the glia,
but only overlap the lower end for size of neurons. 5. Astrocytes, known for
the many processes attached to their cell body, provide structural support
and their processes often have 'end feet' that abut the basal lamina around
the capillary endothelium or line the exterior surface of the CNS, where they
contribute to the pial-glial external limiting membrane.
Oligodendrocytes
microglia
1. This is a high-power view of two microglia stained with a silver method.
This is what Rio-Hortega used when he first described this cell type in 1919.
2. Microglia are the smallest of the glial cells. Some act as phagocytes
cleaning up CNS debris. Most serve as representatives of the immune
system in the brain. Microglia protect the brain from invading
microorganisms and are thought to be similar in nature to microphages in
the blood system. 3. They have spindley processes eminating from the
central cell body. On H&E stain, all one would be able to see is a small rodshaped nucleu
4. This H&E stained section shows a microglial nodule in
a brain of a patient who died with AIDS. It is a common finding in patient with
AIDS encephalopathy. Such nodules probably form in response to viral
antigens: HIV itself and/or CMV.

1. Simple squamous epithelium is made up of one layer of flat cells. This
picture shows the lining of an artery. 3. These cells come off the stratified
squamous epithelial tissue on the inner surface of the cheek. These cells
show the irregular, flat shape characteristic of typical "squamous cells." The
nucleus (A) is centrally located, the cell membrane (C) is very thin, and the
cell is filled with cytoplasm (B). 4. A) line the walls of blood vessels; at the
right it makes up the lung alveoli (A) wall.In both cases the cells are very

Ciliated
1. Human epithelium lining of the small intestine. Arrow shows the cilia. 2.
The epithelium is ciliated in border. 3. This image is labeled with connective
tissue, basement membrane, cilia, lumen 4. The establishment of a ciliated
cell line will provide a valuable resource for the further studies of the
Fallopian tube in the early events of pregnancy.
Non Ciliated
1. This image labeled the connective tissue, cucleus of columnar, goblet cell
and the basement membrane. 2. This image labeled the basement
membrane, connective tissue, goblet cell and the lumen of intestine(free
edge, apical surface) 3. This tissue is characteristic of most of the GI tract.
In this section of the large intestine, the lumen is on the right. Notice the
long, skinny cells, with nuclei at their base, lined up like dominoes in single
file. The large clear spaces are goblet cells, which produce mucous for
lubrication of the intestinal lining. 4. This is an oil-immersion (1000 X) view of
a section of the large intestine. Individual columnar cells are clearly seen. In
addition, the goblet cells are especially prominent. At this power, it is easier
to see the microvilli of the brush border.
Keratinized
1. The cells on the surface of stratified squamous keratinized epithelium are
very flat. Not only are they flat, but they are no longer alive. They have no
nucleus or organelles. They are filled with a protein called keratin, which is
what makes our skin waterproof. The arrow at the top of the image is
pointing to a keratinized cell that has partially separated from the rest of the
skin. These dead cells are continually lost from the surface of the skin, and
are replaced by new cells from the layers below. 2. This high magnification
image of the section from a thin skin shows the keratinized stratified
squamous epithelium that makes up the epidermis and the underlying
dermis of dense, irregular collagenous connective tissue. The portion of this
epithelium closest to the dermis is composed of a living cells, which have
with nuclei and basophilic cytoplasm. The outer portion is composed of
Non Keratinized
1.Human esophagus cross section is lined with non-keratinize. 2. This
image is labeled with free edge, basement membrane and connective tissue.
3. All the squamous cell out to the surface have nuclei 4. Note that the
cervical glands are wide, numerous, and branching. The glands are lined by
simple columnar epithelium. The cervical canal is lined also by simple
columnar epithelium. This epithelium abruptly changes to nonkeratinized
stratified squamous epithelium near the external os. Note on the vaginal side
of the slide there is an absence of glands but many veins.

1. Cross-sectional view through a duct of a sweat gland illustrating stratified
cuboidal epithelium. 2. Stratified cuboidal epithelium lines the ducts of sweat
glands. 3. In which, more than one layer of cuboidal cells are found arranged
on a basement membrane. It occurs in some parts of the reproductive
system, ducts of sweat glands and in the lining of the pharynx. 4. Two
adjacent seminiferous tubules, separated by connective tissue (CT), are
present in the image. The germinal epithelium is composed of stratified
cuboidal cells in various stages of spermatogenesis. Spermatozoa (Sz) are
vaguely visible in the tubule lumens.

1. Stratified Columnar epithelium is rare. One place you can find it is in the
largest ducts of salivary glands. The basal layer of cells are cuboidal cells
and the layer nearest the apical surface includes columnar cells. The large
droplets are mucus, in Goblet cells. 2. A large submaxillary gland is labeled
with yellow arrow. 3.A double layer of stratified columnar cells enclose the
lumen of a salivary duct in the submandibular gland. Even though the
plasma membranes of the cells are obscure, the cells can be identified as
being columnar because the nuclei are located at the base of the cells. The
duct is surrounded by connective tissue (CT) in which darkly stained
fibroblast (Fb) nuclei can be seen. 4, This image is labeled with Lumen and
goblet cell
Transitional
1. Transitional Epithelial cells can slide by one another allowing the
epithelium to get thinner (as in a full bladder) without losing the ability to
form a strong layer. 2. Two diagnostic characteristics are: luminal cells -are
sometimes binucleate and "balloon" out into the lumen giving an uneven
appearance to the luminal surface.3. This image is labeled with connective
tissue, blood vessel and lumen 4.a collapsed layers of the transitional cells,
b. surface of the collapsed ureter.
Pseudostratified
1. Pseudostratified columnar epithelium is made up of one layer of columnar
cells which frequently look like multiple layers. 2. (A)This tissue all begin at
the basement membrane, only a few reach the surface. (B): cilia are easily
seen on the surface. (C): the nuclei appear at various levels giving the tissue
a stratified appearance. FUNCTION: Secretion and movement of mucus by
ciliary action 3. Not a true stratified tissue, nuclei of cells are at different
levels, all cells are attached to basement membrane but not all reach the
apical surface. 4. This image are labeled with cilia, basement membrane,
goblet cell and hyaline cartilage.
