Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Cardiac centre can moderate the cardiac functions through
A
Somatic neural system
B
Parasympathetic nervous system only
C
Autonomic nervous system (ANS)
D
Sympathetic nervous system only
Explanation: 

Detailed explanation-1: –A special neural centre in the medulla oblongata can moderate the cardiac function through CNS.-Parasympathetic neural signals increase the rate of heartbeat.

Detailed explanation-2: -The neural regulation of the cardiac activity is done by a neural centre which is present in the medulla oblangata. The sympathetic and the parasympathetic nervous systems, which are a part of the autonomic nervous system, play an important role in this regulation.

Detailed explanation-3: -Strength of ventricular contraction and thereby the cardiac output.

Detailed explanation-4: -The autonomic nervous system (ANS) is a major regulator of the cardiovascular system. It regulates heart rate and blood pressure in the short-term to cope with everyday situations.

Detailed explanation-5: -A special neural centre in medulla oblongata can moderate the cardiac function through the autonomic nervous system (ANS). Neural signals from the sympathetic nerves (part of ANS) can increase the rate of heartbeat, the strength of ventricular contraction and thereby the cardiac output.
