Vedclass · Answer

(A) The heart rate is regulated by the autonomic nervous system. The parasympathetic nervous system,which slows down the heart rate,is primarily mediated by the $X^{th}$ cranial nerve,also known as the Vagus nerve. This nerve sends inhibitory signals to the sinoatrial $(SA)$ node of the heart to decrease the heart rate.

Which cranial nerve is responsible for the regulation of heart rate?
