Answer 1

sympathetic and parasympathetic

Question 2

General functions of ANS

Answer 2

-maintenance of homeostasis without conscious thought
-respiration, circulation, digestions, body temp, metabolism, sweating, and the secretions of certain endocrine glands

Question 3

Where are preganglionic cell bodies located in the sympathetic nervous system?

Answer 3

between T1 and L2 (thoracolumbar division)

Question 4

Where do axons project in the sympathetic nervous system?

Answer 4

sympathetic ganglia: sympathetic chain ganglia and collateral ganglia

Question 5

Where are preganglionic cell bodies located in the parasympathetic system?

Answer 5

within craniosacral division; axons from the brain are in cranial nerves III, VII, IX, and X and from the spinal cord in pelvic splanchnic nerves

Answer 8

all receptors on parasympathetic effectors, receptors of some sweat glands
