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
