L11: Intro to CVR Flashcards
Contract prostate gland
Sympathetic
alpha 1
Increase activity of salivary glands
Sympathetic
alpha 1
Eccrine glands are
Sympathetic, but M3
reflex tachycardia can be inhibited with
atropine
Relaxation of bronchiolar smooth muscle
Sympathetic
B2
(no innervation, only by circulating epi)
Post synaptic regulation
Up-regulation of receptors (or denervation)
Down-regulation or desensitization of receptors (from excessive stimulation)
Other modulators regulating membrane potentials such as IPSP M2 or EPSP peptides
Ciliary muscle
Parasympathetic: accomodation
M3
(also Beta relax it)
Predominant GU/GI tone
Parasympathetic
M3
Integration center of the baroreceptor reflex
nucleus of the tractus solitarius
Presynaptic receptors which inhibit sympathetic release of NE
alpha 2 (autologous, SNS, bind NE) M2 (heterologous, PNS, bind ACH)
Iris muscle
sympathetic: mydriasis
alpha 1
Contract blood vessels in skin, splanchnic vessels
Sympathetic
alpha 1
the vasomotor center signals
SNS: increase HR, contractility, venous tone (reflex tachycardia)
-OR-
PNS: decrease HR, increase PVR (reflex bradycardia)
Promote ejaculation
Sympathetic
alpha 1
Endothelial blood vessel tone is regulated by
NO release
