The Cardiovascular Centers of the Medulla Oblongata May Be Subdivided

Question

The cardiovascular centers of the medulla oblongata may be subdivided into ________.
A) apneustic and pneumotaxic
B) apneustic and cardiac
C) cardiac and vasomotor
D) cardiac and pneumotaxic
E) apneustic and vasomotor

Accepted Answer

The cardiovascular centers of the medulla oblongata may be subdivided into cardiac and vasomotor. The cardiac center regulates the rate and force of the heartbeat, while the vasomotor center regulates blood vessel diameter and thus blood pressure. None of the other options accurately describe the subdivision of the cardiovascular centers in the medulla oblongata.
