- Cranial Nerve X-Vagus Nerve. The vagus nerve, identified as cranial nerve X, originates in the area between the pons at the base of the brain stem and the spinal column, and extends down through the neck into the chest and abdomen.he vagus nerve includes both sensory and motor nerves and, although they contain both voluntary and involuntary branches, the involuntary members predominate. The voluntary components are motor fibers that carry impulses to muscles in the larynx to aid in speech and swallowing. Other sensory ...

List of Cranial Nerves 2 -- The Optic Nerve. The optic nerve is a sensory nerve responsible for vision. It transmits signals from the retina in the eye back to the visual cortex in the posterior lobes of the brain traversing the skull through the optic canal.

Olfactory nerve The olfactory nerve (Latin: nervus olfactorius) is typically considered the first cranial nerve, or simply CN I.esions to the olfactory nerve can occur because of blunt trauma, such as coup-contra-coup damage, meningitis, and tumors of the frontal lobe. They often lead to a reduced ability to taste and smell.

The Cranial Nerve Exam The twelve cranial nerves serve the head and neck. The vagus nerve (cranial nerve X) has autonomic functions in the thoracic and superior abdominal cavities. The special senses are served through the cranial nerves, as well as the general senses of the head and neck.The movement of the eyes, face, tongue, throat, and neck are all under the control of cranial nerves.he olfactory, optic, and vestibulocochlear nerves (cranial nerves I, II, and VIII) are dedicated to four of the special senses: smell, vision, equilibrium, and hearing, respectively. Taste sensation is relayed to the brain stem through fibers of the facial and glossopharyngeal nerves.

Vagus Nerve and Vagus Nerve Disorder The vagus nerve is actually two cranial nerves that extend from the brain stem and connect down to the viscera. Sometimes this nerve is referred to as cranial nerve X, the 10 th cranial nerve or the wandering nerve.hese nerves are used to send a variety of signals throughout the body, but will also transfer signals back to the brain. The vagus nerve is also known for wandering through the body, weaving through the abdomen and branching into other nerves that extend through the limbs and organs.

Cranial nerves Cranial nerves are the nerves that emerge directly from the brain, in contrast to spinal nerves. 10 of 12 of the cranial nerves originate in the brainstem. Cranial nerves relay information between the brain and parts of the body, primarily to and from regions of the head and neck. Spinal nerves emerge sequentially from the spinal cord with the spinal nerve closest to the head emerging in the space above the first cervical vertebra. The cranial nerves, however, emerge from the central nervous sys

Nervous System Anatomy This nerve is cranial nerve X. It is the only cranial nerve to pass into the body cavities below the neck. It is primarily parasympathetic in nature and is the major nerve affecting the heart and most of the gastrointestinal tract. It slows the heart down and speeds up the activity of the gastrointestinal tract.

- THE CRANIAL NERVES. The twelve pairs of cranial nerves are continuous with the brain and are numbered from anterior. to posterior, according to their attachments to the brain. CN-I is attached to the cerebral hemispheres. CN-II is attached to the central cerebrum via the. optic chiasma (hypothalamus), CN-III and IV to the midbrain.

What is the Vagus Nerve? The vagus nerve is either one of two cranial nerves which are extremely long, extending from the brain stem all the way to the viscera. The vagus nerves carry a wide assortment of signals to and from the brain, and they are responsible for a number of instinctive responses in the body.
