Cranial nerves The  cranial nerves provide motor and sensory innervation mainly to the structures within the head and neck. The vagus nerve (X) provides sensory and autonomic (parasympathetic) motor innervation to structures in the neck and also to most of the organs in the chest and abdomen.

Phrenic nerve The phrenic nerve is a mixed motor/sensory nerve that courses through the neck and thorax to innervate the diaphragm. Arises from the ventral rami of the C3, C4 and C5 nerve roots, part of the cervical plexus.he phrenic nerve is the sole motor supply to each hemidiaphragm. It also provides sensory supply to: 1  diaphragm (except the most peripheral diaphragm, which is supplied by intercostal nerves). 2  mediastinal pleura.

Facial nerve 1 In the temporal part of the facial canal, the nerve gives to the stapedius and chorda tympani. 2  The chorda tympani supplies taste fibers to the anterior two thirds of the tongue, and also synapses with the submandibular ganglion.

Vagus Nerve Anatomy Gross Anatomy. The vagus nerve is the longest cranial nerve. It contains motor and sensory fibers and, because it passes through the neck and thorax to the abdomen, has the widest distribution in the body. It contains somatic and visceral afferent fibers, as well as general and special visceral efferent fibers.(See Table 1, below.).he recurrent laryngeal nerve is also known as the inferior laryngeal nerve. The right nerve branches from the vagus at the root of the neck around the right subclavian artery. It courses superiorly in the tracheoesophageal groove to enter the larynx between the cricopharyngeus and the esophagus.

Trigeminal Nerve (Cranial Nerve V) The trigeminal nerve or cranial nerve V contains sensory from the gasserian ganglion and motor fibers. This nerve has three major branches or divisions, the ophthalmic (V1), maxillary (V2), and mandibular (V3), which supply the eye, deep and superficial structures of the face, and the cranium. The motor component is located in the mandibular division and it supplies mainly the muscles of mastication.

- This portion of the spinal cord innervates the neck and arms. The section is divided into eight individual sections that each control specific functions of the neck and arms. Nerves of this area receive information from sensations felt in the upper body and send these messages to the brain.

Eardrum Sensory innervation of the external surface of the tympanic membrane is mainly by the auricotemporal nerve, a branch of the mandibular nerve [V3]. It also has contributions from the auricular branch of the vagus nerve [X], the facial nerve [VII] and a possible contribution from the glossopharyngeal nerve [IX].

- The nerves that supply the muscles and the skin in the upper extremity leave the spinal cord in a complicated network of nerve fibers, roots and bundles—this is called the brachial plexus. These nerves travel down the side of the front of the neck and divide, then rejoin to form the median, radial and ulnar nerves.

Nerves of the Head and Neck Eight spinal nerves branch off from the spinal cord in the neck to form a network of nerves called the cervical plexus. The cervical plexus forms many connections between the brain and the skin and muscles of the head and neck, similar to the cranial nerves. A vital connection from the cervical plexus to the diaphragm is formed by the phrenic nerve, allowing the brain to control breathing.

Nerves of the Head and Neck The spinal cord is a thick nerve trunk that forms the brain’s most important connection to the body and carries all signals to and from the brain that are not provided by the cranial nerves.The spinal nerve extends from the inferior end of the brain stem and passes through the foramen magnum of the skull into the neck.ight spinal nerves branch off from the spinal cord in the neck to form a network of nerves called the cervical plexus. The cervical plexus forms many connections between the brain and the skin and muscles of the head and neck, similar to the cranial nerves.

Vagus Nerve Anatomy The recurrent and external branches of the superior laryngeal nerves carry parasympathetic fibers from the dorsal motor nucleus to the subglottis and supraglottic regions, respectively. The superior cervical ganglion sends sympathetic innervation.he vagus nerve is the longest cranial nerve. It contains motor and sensory fibers and, because it passes through the neck and thorax to the abdomen, has the widest distribution in the body. It contains somatic and visceral afferent fibers, as well as general and special visceral efferent fibers. (See Table 1, below.).

Spinal Nerves The posterior root is the afferent sensory root and carries sensory information to the brain. The anterior root is the efferent motor root and carries motor information from the brain. The spinal nerve emerges from the spinal column through an opening (intervertebral foramen) between adjacent vertebrae.This is true for all spinal nerves except for the first spinal nerve pair (C1), which emerges between the occipital bone and the atlas (the first vertebra).Thus the cervical nerves are numbered by the vertebra below, except spinal nerve C8, which exists below vertebra C7 and above vertebra T1.The thoracic, lumbar, and sacral nerves are then numbered by the vertebra above.he posterior root is the afferent sensory root and carries sensory information to the brain. The anterior root is the efferent motor root and carries motor information from the brain. The spinal nerve emerges from the spinal column through an opening (intervertebral foramen) between adjacent vertebrae.

Lingual nerve The lingual nerve supplies general somatic afferent innervation from the mucous membrane of the anterior two-thirds of the tongue, while the posterior one-third is innervated by the glossopharyngeal.arning of patients of nerve injury prior to administration of deep dental injections has a risk of injury in approximately 1:14,000 with 25% of these remaining persistent. Routine preoperative warnings about these injuries is routinely undertaken in the US and Germany.

Cranial Nerves - Anatomy & Physiology However, parasympathetic innervation comes from several cranial nerves including the oculomotor nerve (cranial nerve III), the vestibulocochlear nerve (cranial nerve VIII), the glossopharyngeal nerve (cranial nerve IX) and the vagus nerve (cranial nerve X).

The Brachial Plexus Fig 1- Proximal portion of the brachial plexus, in the neck. The brachial plexus is a network of nerve fibres that supplies the skin and musculature of the upper limb. It begins in the root of the neck, passes through the axilla, and enters the upper arm. The plexus is formed by the anterior rami (divisions) of the cervical spinal nerves C5, C6, C7 and C8, and the first thoracic spinal nerve, T1.

- The vagus nerve is part of the group of cranial nerves responsible for innervation of structures derived from the branchial arches. It is also part of a group together with the glossopharyngeal and accessory nerves that passes through the jugular foramen which is termed the vagus group.rigeminal nerve (V). The trigeminal nerve is part of the cranial nerve group responsible for innervation of structures originating from branchial arches. The trigeminal nerve nuclei is in the area of the pons and medulla oblongata and is the nerve of the 1st branchial arch.

cranial nerve Cranial nerves supply the sense organs and muscles of the head, neck, and viscera. Like spinal nerves, cranial nerves have dorsal and ventral roots (see nerve root) and each root is numbered and named as a separate nerve. Twelve cranial nerves are conventionally recognized in humans.

Accessory nerve Accessory nerve. (Redirected from Accessory nerves) The accessory nerve is a cranial nerve that supplies the sternocleidomastoid and trapezius muscles. It is considered the eleventh of twelve pairs of cranial nerves, or simply cranial nerve XI, as part of it was formerly believed to originate in the brain.
