Manikens
WHAT WE LEARNED AND HOW WE LEARNED IT
Using the Manikens

By Using the Manikens…
Human Skeletal System
Human Muscular System
That isn’t it!

Dissections
(THE BEST PART)
The Cow Elbow
Learned about:
http://atsbiomed.weebly.com/blog/category/hbs
•
Different joint types
•
Movement terminology
•
The purpose of synovial fluid
The Kidney
Capsule
Renal Artery
Inside the Kidney
Cortex
We learned about…
•
Nephrons and how they function
•
Structures of the kidney and their
functions
•
Why we only need one kidney
•
Urine formation pathway
Renal Vein
Calyx
Ureter
Medullary
Pyramid
The Cow Eye
Also in the lab…
What we learned:
▪ Where visual signals are
processed in the brain
▪ Differences between cow eyes
and human eyes
▪ The structures of the eye and
their functions
▪ The pathway of light through the
eye

▪ How light affects the pupils
The Central Nervous System

Parasympathetic
Division
Region of the Brain
Location
Primary Function
Specific Activities and Processes
Occipital Lobe (Cerebrum)
Back of the brain, slightly towards
the bottom
Processes visual input that is sent
to the brain from the retinas
Vision
Frontal Lobe (Cerebrum)
Front of the brain, at the top
Executing behavior; controls
individual muscles
Happiness, movement, problem
solving, reasoning, speech
production
Parietal Lobe (Cerebrum)
Behind the frontal lobe, in front of
occipital
Contains neurons that receive
sensory information
Bodily sensations
Temporal Lobe (Cerebrum)
Above brain stem
Combines auditory and visual
information
Hearing, language comprehension,
smell
Medulla
In the brain stem, in front of
cerebellum
Helps transfer messages to spinal
cord, controls breathing,
heart/blood vessel function,
digestion, sneezing, and
swallowing
Breathing, BP regulation
Pons
Above medulla
Sensory analysis, motor skills,
sleep and consciousness
Sleeping and waking
Hypothalamus
Just above brain stem
Hormone production, homeostasis
Thirst, hunger, smell
Amygdala
Middle of temporal lobe
Processing of emotions
Happiness
Hippocampus
Next to amygdala
Long term memory, spatial
navigation
Remembrance
Cerebellum
Bottom of the brain, in the back
Fine motor skills, balance, posture,
quick/repetitive movements
Muscle coordination, balance,
movement
Sherlock Bones Lab
Calipers
They measure lengths. In this case, bones!
What You Can Determine Using Bones
• Gender
• Race
• Height
• Age
Height Estimation of YOU!
Femur
▪ Male: (2.32 X MLF) + 65.53 +/- 3.94
▪ Female: (2.47 X MLF) + 54.10 +/- 3.72
Humerus
▪ Male: (2.97 X MLH) + 73.5 +/- 3.94
▪ Female: (3.14 X MLH) +65 +/- 3.72
(There’s more specifics involved too!)
Other Areas the Course
Has Helped
In Other Courses…

Body cells
take up more
glucose
Beta cells of
pancreas
release
insulin into
the blood
Liver takes
up glucose
and stores it
as glycogen
Negative Feedback
Loops
Alpha cells of
pancreas
release
glucagon
Liver breaks down
glycogen and
releases glucose
