Question

Heartbeat is controlled by which cranial nerve?
(a) X
(b) IX
(c) III
(d) V

Answer 1

There are 12 sets of cranial nerves. A couple of the cranial nerves I, II, and VIll contain just tangible strands; some III, IV, VI, XI, and Xll contain all or generally engine filaments. The rest of, VII, IX, and X contain both tactile and engine strands; they are known as blended nerves.

Complete answer:
The 10th cranial nerve (X) is the vagus nerve. It is the longest cranial nerve. (Its name signifies "vagabond"). The vagus nerve is answerable for such shifted assignments as directing pulse, gastrointestinal peristalsis, perspiring, and many muscle developments in the mouth, including discourse.
After leaving the medulla oblongata between the olive and the sub-par cerebellar peduncle, the vagus nerve stretches out through the jugular foramen, at that point passes into the carotid sheath between the interior carotid course and the inside jugular vein down to the neck, chest, and midsection, where it adds to the innervation of the viscera, arriving at all the path to the colon. Other than giving some yield to different organs, the vagus nerve contains somewhere in the range of 80% and 90% of afferent nerves generally passing on tactile data about the condition of the body's organs to the focal anxious system. The privilege left vagus nerves to slip from the cranial vault through the jugular foramina, entering the carotid sheath between the inward and outer carotid veins, at that point passing posterolateral to the basic carotid corridor.

So the correct answer is X.

Note:
The vagus nerve verifiably referred to as the pneumogastric nerve. It is the 10th cranial nerve or CN X, and interfaces with the parasympathetic control of the heart, lungs, and stomach related lot. The vagus nerves are regularly alluded to in the particular. It is the longest nerve of the autonomic sensory system in the human body and contains tangible and engine strands. The tactile filaments start from neurons of the nodose ganglion, though the engine strands come from neurons of the dorsal engine core of the vagus and the core is ambiguous.
