Question

1. Write a paragraph of 3-5 sentences describing 1) whether the statement is correct or incorrect and 2) the reasoning for your answer. Your answer should demonstrate your understanding of the physiological concepts underlying the statement and be written professionally.

An injury to the vagus nerve will cause heart rate to decrease.

Please be thorough and give factual physiological reasoning.

Answer 1

False.

The injury to the vagus nerve increases the heart rate.

The vagus nerve is the 10th cranial nerve of the body.This nerve besides supplying the various body parts,plays a major role in the regulation of the heart rate.This vagus nerve mediates the parasympathetic innervation of the heart.The vagus nerve acts to decrease the heart rate.The right vagus nerve innervates the Sinoatrial node.The vagus nerve when stimulated causes bradycardia.So an injury to the vagus nerve removes the control of the heart beat and in the aabsence of thus paraysmpathetic control the heart rate increases.
