Question

baroreceptors in blood vessels

Accepted Answer

if blood pressure too high, impulses sent to medulla which decreases heart rate, medulla sends impulses along parasympathetic NS to SAN which decreases heart rate and returns blood pressure to normal
if blood pressure too low, impulses sent to medulla which increases heart rate, medulla sends impulses along sympathetic NS to SAN which increase heart rate and returns blood pressure to normal

Front	baroreceptors in blood vessels
Back	if blood pressure too high, impulses sent to medulla which decreases heart rate, medulla sends impulses along parasympathetic NS to SAN which decreases heart rate and returns blood pressure to normal if blood pressure too low, impulses sent to medulla which increases heart rate, medulla sends impulses along sympathetic NS to SAN which increase heart rate and returns blood pressure to normal
