1. Having the quality of acting on the nerves, so as to restore them to a normal state; relieving disorders of the nervous system.
2. A reference to the nerves or sinews.

Of or relating to the nerves.

A nerve which consists of two separate parts of the eighth pair of cranial nerves connecting the inner ear with the brain and transmitting impulses concerned with hearing and balance: The acoustic nerve controls the special senses of hearing and equilibrium or balance.

The eighth cranial nerve, or vestibulocochlear nerve (relating to the vestibule and the cochlea of the ear): The auditory nerves connect the inner ear with the brain.

The auditory nerves innervate the ear and carry impulses relating to both sound stimuli and balance to the brain.

The nerves in the armpits: Some of the fibers of the axillary nerves supply the capsules that surround the shoulder joints with connective tissue.

When Sally's little brother tickled her axillary nerves, she couldn't keep herself from laughing and, after a while, it started to be painful to laugh so much!

The twelve nerves of the brain, that emerge from or enter the skull (the cranium) as opposed to the spinal nerves; which emerge from the vertebral column:

1. Olfactory nerve (carries impulses for the sense of smell from the nose to the brain).
2. Optic nerve (carries the impulses formed by the retinas of the eyes which are dispatched through the optic nerve to the brain and interprets them as images).
3. Oculomotor nerve (nerve supply to muscles around the eyes and upper eyelid muscle which raises the eyelid; the extraocular muscle which moves the eye inward; and the pupillary muscle which constricts the pupils).
4. Trochlear nerve (nerve supply to the superior oblique muscles of the eyes, one of the muscles that moves the eyes; the only cranial nerve that comes from the back of the brain stem and follows the longest course within the skull of any of the cranial nerves).
5. Trigeminal nerve (functions both as the chief nerve of sensation for the face and the motor nerve controlling the muscles of mastication [chewing]).
6. Abducent nerve (supplies the muscles called the lateral rectus muscles which move the eyes outward).
7. Facial nerve (supplies the muscles of facial expression, salivary glands, and taste buds).
8. Vestibulocochlear nerve (responsible for the sense of hearing and it is also pertinent to balance and the sense of body positions).
9. Glossopharyngeal nerve (supplies the tongue, throat, and one of the salivary glands [the parotid gland largest of the three major salivary glands]; muscles involved in swallowing and taste).
10. Vagus nerve (supplies nerve fibers to the pharynx [throat], larynx [voice box], trachea [windpipe], lungs, heart, esophagus and most of the intestinal tract [as far as the transverse portion of the colon] and it brings sensory information back from the ear, tongue, pharynx and larynx).
11. Accessory nerve (supplies the sternocleidomastoid [muscle in the front of the neck which turns the head] and the trapezius muscles [either of two flat triangular muscles of the shoulder and upper back that are involved in moving the shoulders and arms, turns the face to the opposite side, and helps to pull the head back]).
12. Hypoglossal nerve (enervates the muscles of the tongue).

A branch of the inferior alveolar (tip of the tongue) nerve that emerges from the bone of the mandible near the bottom of the jaw: The mental nerve divides into branches which are distributed to the skin of the chin and the mucous membranes of the lower lip.

Any of the nerves supplying the nasal mucosa: These olfactory nerves consist of delicate bundles of fibers that pass through the bipolar receptor neurons of olfactory mucous membranes.

A nerve that supplies nerve fibers to the pharynx (throat), larynx (voice box), trachea (windpipe), lungs, heart, esophagus (passage from the mouth to the stomach), and the intestinal tract; as far as the transverse part of the colon: The vagus nerve emerges from the medulla oblongata (part of the brain stem) and it is classified as a cranial nerve because it comes from that brain stem.

The vagus nerve transmits sensory information back to the brain from major organs in the body; including the ears, the tongue, the pharynx, the larynx, and much of the digestive system.

A complete interruption of the vagus nerve causes a condition in which the voice is hoarse and nasal, and the vocal cord on the affected side is immobile; resulting in difficulty in swallowing (dysphagia) and speaking (dysphonia).

The vagus nerve also stimulates the production of stomach acid and pancreatic juice; stimulates the activity of the gallbladder, and increases the rhythmic muscular contractions that move food through the digestive tract.
