Physiology: baroreceptor reflex control of BP Flashcards
1
Q
what is a baroreceptor
A
nerves that sense BP changes by stretch in blood vessels
2
Q
what kind of BP changes do baroreceptors respond to
A
only respond to acute changes
3
Q
where are arterial baroreceptors found
A
aortic arch and carotid sinus
4
Q
when stimulated where does arterial baroreceptors send impulses
A
to medulla then to cardiovascular centre in the Pons
5
Q
what does the vasomotor control centre do
A
controls diameter of blood vessels(sympathetic)
6
Q
what does the cardiac control centre do
A
cardiac accelerator(sympathetic) cardiac decelerator(parasympathetic)
7
Q
where are the cardiopulmonary baroreceptors found
A
in low pressure areas(e.g. pulmonary arteries)
8
Q
what do the cardiopulmonary baroreceptors regulate
A
blood volume
