Moment 333 Flashcards
sympathetic efferent division - what hormones?
ACH and NE
parasympathetic efferent division - what hormone?
only ACH AND only through direct innervation
ach receptors are..nic
nicotinic and always excitatory - just means they will always send the message - never not fire
muscarinic - on effector CELL - that means ONLY (relax your muscarals)
parasympathetic - can be excitatory or inhibitory
adrenergic - on effector ORGAN (always sympathetic or parasympathetic?)
always sympathetic
adrenergic receptors - again, always sympathetic are..(adriene always a spaz)
alpha (a) receptors - binds w/ NE and E - usually excitatory (constriction of arterioles - NOT fight or flight organs, ie digestive, etc)
beta (b) receptors:
b1 - binds w/ NE and E, mostly in heart, excitatory
b2 - binds mostly with E, response is inhibitory (dilation of arterioles)
Somatic nervous system -
always terminates on muscle cell = always excitatory
Bronchioles respond to
CO2
arterioles respond to..
02

plasma proteins can get out
micelles
help small intestine absorb fat
movement in large intestine
haustral
kill parasites
eosinophils
converts vitamin D to its active form
kidneys
if you have high bp, you vasodilate…
and gfr would increase, allowing you to filter more fluids and lower bp
tubular reabsorption
getting back most of the Na, and then H2o follows.
angio II
vasoconstricts arterioles, which will raise BP. it also causes the adrenal cortex to release aldosterone. this will insert more Na pumps into DCT and increase blood volume, then bp.
ANP does the opposite of…
angio II
glucose reabsorption in kidneys is…(type of transport)
secondary active transport bc it’s hitching a ride with Na
mac the…

help!
important for homeostatis
