Cranial nerves and function
function- eyelid and eyeball movement

Divisions of autonomic nervous system
This division is the emergency division. Which means that it prepares the body for energy and it also protects the body from injuries.
Dilates the pupil
relaxes the bladder
accelerates heart rate
"Fight or flight"
This division is the complete opposite from the sympathetic. What this division does is that it replaces and recovers from activities.
Stimulates tear glands
Endocrine glands and functions
Portion of the brain that maintains the bodies internal balance. Hypothalamus is the link between endocrine and nervous systems.
The hypothalamus does this by helping stimulate sleep cycles, heart rate, blood pressure, body temperature, appetite, body weight, and etc.
Located deep in the center of the eye.
Produces melatonin. Melatonin helps maintaining circadian rhythm and regulating reproductive hormones.
small organ shaped like a pine cone
Hormones of pituitary gland help regulate functions of endocrine glands.
Has two parts- anterior lobe and posterior lobe.
Its hormones control other parts of the system. (example thyroid gland,testes, adrenal glands, and etc.)
Thyroid regulates the metabolism.
The two main thyroid hormones are T3 and T4.
This regulates the body's calcium levels.
There are four parathyroid glands and each of them are tiny.
They are not relating to the thyroid despite of their location.
PTH (parathyroid hormone)
Located behind the sternum and behind the lungs. After puberty the thymus starts to shrink.
Thymosin is the hormone produced by thymus and it helps stimulate the development of T-Cells.
Two glands that sit on top of the kidneys.
(outer part) produces hormones that are important. (example cortisol)
-(inner part) produces hormones that we can live without. (example adrenaline)
Maintain the bodies blood glucose balanced.
Primary hormones are insulin and glucagon. (both of these regulates blood glucose)
The maintain the health of a female reproductive system.
They secrete two main hormones (estrogen and progestogen)
They secrete testosterone
Maintain the health of the male reproductive system.
