The PNS is divided into these two categories
Autonomic (involuntary), Somatic (voluntary)
The ANS is divided into these two categories
Parasympathetic, Sympathetic
what does the parasympathetic division do?
Controls body functions at rest
what does the sympathetic division do?
fight or flight response 
what is the telencephalon?
Cerebral cortex (including basal ganglia)
What is the diencephalon? What is its function?
- Thalamus, Hypothalamus, Pineal Gland
- Connects endocrine with nervous system
What is the function of the midbrain?
regulate movement, process auditory & visual information, and connect forebrain to hindbrain
What is the function of the hindbrain?
Regulate autonomic functions, balance, equilibrium, and relay of sensor information
The Hindbrain is comprised of these three structures
Ponds, cerebellum, and medulla
