34. Which of the following is true regarding baroreceptors?
(A) Increasing the pulse pressure will increase firing rate of action potentials in the afferent neuronsassociated with the baroreceptors.
(B) The medullary cardiovascular center is the only part of the brain involved in the baroreceptor reilex
(C) Activation of the baroreceptor reflex is primarily involved in long-term regulation of systemicblood pressure.
(D) Acute blood loss elicits increased firing rate of arterial baroreceptors.
