Autonomics Flashcards
M2
Heart - PNS - decrease HR, decrease conduction velocity, decrease contractility
M3
Blood Vessels - constriction of VSM and NO release dilation of endothelium
Respiratory - bronchiolar constriction, secretion = relaxation, mucus
GI - increase motility, relaxation and secretion = defecation
GU - Contraction of bladder detrusor, relaxation of trigone and sphincter, penile erection = urination, sexual
Eye - Contraction of iris sphincter and contraction of lens ciliary muscle = accomodation
Salivary glands - salivation
Nn
Adrenal Medulla - SNS epi release
Autonomic ganglia - SNS and PNS, EPSP
Nm
Skeletal muscle - contraction
Adrenergic receptors
A1 A2
B1 B2 B3
B1
Heart - increase HR, contractility, conduction velocity
Kidney - secrete renin
A1
Blood vessels - constriction and dilation of skeletal muscles, skin and mucosa constriction Trigone - contraction Penis -ejaculation Eye - iris radial muscle contraction Uterine SMC - contraction
A2
Adrenergic neurons - decrease NT release
B2
Bronchioles - bronchiolar dilation Skeletal muscle vessels - dilation Bladder detrusor - relaxation Lens ciliary - relax to focus on far Uterine SMC - relaxation Liver - glycogenolysis
B3
Bladder - relaxation
Cholinergic Receptor
ACH
Muscarinic - M2, M3, Nn
