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. 3  pericardium. 4  central parts of diaphragmatic pleura and peritoneum.

Nerve plexus A nerve plexus is a plexus of intersecting nerves. A nerve plexus is composed of afferent and efferent fibers that arise from the merging of the anterior rami of spinal nerves and blood vessels. There are five spinal nerve plexuses, except in the thoracic region, as well as other forms of autonomic plexuses, many of which are a part of the enteric nervous system. The nerves that arise from the plexuses have both sensory and motor functions. These functions include muscle contraction, the mainten

Phrenic Nerve Phrenic Nerve: motor nerve of the diaphragm; phrenic nerve fibers originate in the cervical spinal column and travel through the cervical plexus to the diaphragm.he phrenic nerve innervates contractions of the diaphragm, which is vital to respiration. It also innervates some sensation to the chest and upper abdomen. Conditions that afflict the phrenic nerve include hiccups, trauma, muscular dystrophy, tumor, neuropathy, and infection.

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.

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.

Brachial Plexus Anatomy Overview. The brachial plexus (plexus brachialis) is a somatic nerve plexus formed by intercommunications among the ventral rami (roots) of the lower 4 cervical nerves (C5-C8) and the first thoracic nerve (T1).he trunks of the brachial plexus pass between the anterior and middle scalene muscles. The ventral rami of C5 and C6 unite to form the upper trunk. The suprascapular nerve and the nerve to the subclavius arise from the upper trunk.

Overview The sacral plexus is derived from the anterior rami of spinal nerves L4, L5, S1, S2, S3, and S4. Each of these anterior rami gives rise to anterior and posterior branches. The anterior branches supply flexor muscles of the lower limb, and posterior branches supply the extensor and abductor muscles.
