Answer 3

• control autonomic functions (digestion, respiration, heart rate, blood pressue)
  -coordinates function of endocrine system via pituitary gland
  -regulates body temp

Question 4

structural difference of sympathetic vs. parasympathetic

Answer 4

location preganglionic:
s- lat gray horns from t1-L2
ps- brainstem and lt. portion of ant gray horn s2-s4
location PNS ganglia:
s- sympathetic chain and collateral, adrenal medulla(vertebral column)
ps- intramural or terminal
neurotransmitter ( near or in target organs)
s- pre, acetylcholine post, norepinephrine
ps - pre, ach post, ach

Question 5

location of symapthetic ganglia

Answer 5

-sympathetic chain (both sides vertebral column
-collateral ( superior mesenteric ganglion, celiac ganglion and -inferior mesenteric ganglion)
adrenal medulla ( adrenal gland- release norepinephrine)

Question 6

terminal vs intrmural

Answer 6

terminal= near target organ
intramural= within target organ
