The rate of heartbeat is regulated by the integrated activity of inhibiting and accelerating effects

Question

The rate of heartbeat is regulated by the integrated activity of inhibiting and accelerating effects occurring in which part of the brain?\

Professor PC Thomas Classes · Answer

(c) : A special neural centre in the medulla oblongata can moderate the cardiac function through autonomic nervous system (ANS). Neural signals through the sympathetic nerves (part of ANS) can increase the rate of heartbeat, the strength of ventricular contraction and thereby the cardiac output. On the other hand, parasympathetic neural signals (another component of ANS) decrease the rate of heartbeat, speed of conduction of action potential and thereby the cardiac output.
