Which cranial nerve wanders outside the head into the thorax and abdomen?

Which cranial nerve wanders outside the head into the thorax and abdomen?

The name “vagus” comes from the Latin term for “wandering.” This is because the vagus nerve wanders from the brain into organs in the neck, chest, and abdomen. It is also known as the 10th cranial nerve or cranial nerve X.

Which nerve sends motor signals for swallowing and moving the head neck and shoulders?

The trigeminal nerve (cranial nerve V), and it contains both sensory and motor fibers. It is responsible for sensation in the face and certain motor functions such as biting, chewing, and swallowing.

Which nerve is responsible for carrying the sound information to the brain?

Sensory nerve- Vestibulocochlear Nerve- controls hearing and balance. Vestibular nerve receives positional information. Cochlear nerve transmits information on sound to the brain.

What term describes the crossing over of a nerve tract to the side of the nervous system opposite to where the axon originated?

There is a decussation (i.e., axons crossing the midline to the opposite side of the spinal cord or brain stem) in each somatosensory pathway below the level of the thalamus.

Which cranial nerve Innervates organs of the thorax and abdomen quizlet?

Which cranial nerve innervates most of the visceral organs? The vagus nerve has many targets in the thoracic and abdominal cavities and innervates many of the visceral organs.

Where is the vagus nerve in the abdomen?

Gastric branches The branches of the right vagus nerve forms the posterior gastric plexus on the postero-inferior surface of the stomach, while the branches of the left vagus nerve forms the anterior gastric plexus on the antero-superior surface of the stomach.

Which of the following nerves controls movements of the neck?

Your accessory nerve is a motor nerve that controls the muscles in your neck. These muscles allow you to rotate, flex, and extend your neck and shoulders. It’s divided into two parts: spinal and cranial.

Which nerves go through openings in the skull and stimulate the head and neck?
