Neuronal Control of BP Flashcards
where are baroreceptors
carotid sinus and aortic sinus
what do baroreceptors respond to
stretch
where is the carotid sinus
just above the bifurcation of the common carotid artery, on teh internal carotid artery
what nerve is the carotid sinus innervated by
sinus nerve branch of glossopharyngeal
which cranial nerve(s) does the sinus nerve join
glossopharyngeal or vagus
which cranial nerve(s) does the sinus nerve join
glossopharyngeal or vagus
where do glossopharyngeal and vagus nerves originate
brainstem
where do most cranial nerves originate
brainstem
where are the CHEMOreceptors in the carotid area
carotid body
what do the chemoreceptors in the carotid body detect
changes in partial pressure of oxygen levels in the blood
what numbers are glossopharyngeal and vagus nerves
9/10
what is CO
HR x SV
MAP=?
CO x TPR
Also (2(DBP) x SBP)/3
what is the NST
nucleus of the solitary tract - where nerves 9 and 10 terminate, in the medulla
chronotropic=
increase or decrease of heartrate
in high BP, what is stimulated by the NTS
nucleus ambiguous (vagus nucleus -> parasympathetic outflow to heart)
