The Sheep Brain vs. The Human Brain
Similarities and Differences of...
The human brain and sheep brain have the major difference that humans can think, are able to have friends, remember what we classify as fun times and be emotional. The human brain has a larger frontal lobe than that of a sheep’s.
The sheep’s brain has a more developed olfactory bulb when compared to the human brain.
The human brain is much heavier and longer than a sheep's but a human brain is rounded whereas a sheep's brain is elongated in shape.
The Sheep Kidney vs. The Human Kidney
Human Kidney
Sheep Kidney
The kidneys share the same functions such as retaining homeostasis, blood pressure, excretion of waste and more.
The sheep's kidneys function differently than human kidneys, producing different proteins and hormones in different quantities.
Similarities and Differences
In our research we've found that the sheep brain is very similar to that of a human's.
There are many structures in the same general area that perform the same function.
For example both the human and sheep have a cerebellum. And although it's not lined up identically they share the same job and that's the ability to control precise movements.
Sheep Brain
The Heart
Cranial Nerves
Cranial nerves are the 12 nerves that can be seen on the bottom surface of the brain.
They bring information from the sense organs to the brain;
Some cranial nerves control muscles and others cranial nerves are connected to glands or internal organs such as the heart and lungs.
12 Cranial Nerves
olfactory - smell
optic – vision
oculomotor- eye movements
trochlear- eye movements
trigeminal – sensations of the face scalp and teeth; chewing motion
abducens- eye movements
facial – sense of taste; contraction of all muscles of the facial expression
vestibulocochlear- hearing; sense of balance
glossopharyngeal- Sensations of the throat taste swallowing movements; secreation of salvia
vagus- sensations of the throat and larynx and of the thoracic and abodinal organs; swallowing, voice production, slowing of the heartbeat, acceleration of peristalsis
accessory- shoulder movements; turning movements
hypoglossal – tongue movements
The heart pumps blood through the body via the circulatory system
The circulatory system supplies our cells' transportation needs
The sheep heart and the human heart serve the same function the only difference is that they are different sizes
The Human Eyeball
