Chapter 20, Problem 3CAL
Summary Introduction
Introduction:
Baroreceptor stimulates the vasomotor center to increase the signal along the sympathetic pathway that extends to a blood vessel (vasoconstriction). This results in an increase the blood flow through the blood vessels.

Why is it necessary to stimulate papillary muscles in the ventricle slightly earlier than the rest of the ventricular wall myocardium?
a. to assure rapid conduction speed of the action potential
b. to pull on AV valve cusps to prevent backflow
c. to assure blood will surge toward the semilunar valves
d. to assure coordinated contraction of the ventricular myocardium
