  2. Ventral root of spinal nerve - Wikipedia

    en.wikipedia.org/wiki/Ventral_root_of_spinal_nerve

    In anatomy and neurology, the ventral root of spinal nerve, anterior root, or motor root [1] is the efferent motor root of a spinal nerve. At its distal end, the ventral root joins with the dorsal root to form a mixed spinal nerve .

  3. Ventral ramus of spinal nerve - Wikipedia

    en.wikipedia.org/wiki/Ventral_ramus_of_spinal_nerve

    Branches of the cervical plexus, which include the phrenic nerve, innervate muscles of the neck, the diaphragm, and the skin of the neck and upper chest. The brachial plexus contains ventral rami from spinal nerves C5–T1. This plexus innervates the pectoral girdle and upper limb. The lumbar plexus contains ventral rami from spinal nerves L1–L4.

  4. Spinal nerve - Wikipedia

    en.wikipedia.org/wiki/Spinal_nerve

    The dorsal root is the afferent sensory root and carries sensory information to the brain. The ventral 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.

  5. Dorsal root of spinal nerve - Wikipedia

    en.wikipedia.org/wiki/Dorsal_root_of_spinal_nerve

    The dorsal root of spinal nerve (or posterior root of spinal nerve or sensory root) [1] is one of two "roots" which emerge from the spinal cord. It emerges directly from the spinal cord, and travels to the dorsal root ganglion. Nerve fibres with the ventral root then combine to form a spinal nerve.

  6. Nerve root - Wikipedia

    en.wikipedia.org/wiki/Nerve_root

    Each spinal nerve is a mixed nerve formed by the union of a sensory dorsal root and a motor ventral root, [1] meaning that there are 62 dorsal/ventral root pairs, and therefore 124 nerve roots in total, each of which stems from a bundle of nerve rootlets (or root filaments).

  7. Dorsal ramus of spinal nerve - Wikipedia

    en.wikipedia.org/wiki/Dorsal_ramus_of_spinal_nerve

    Ventral root axons join with dorsal root ganglia to form mixed spinal nerves (below). These then merge to form peripheral nerves. Shortly after this spinal nerve forms, it then branches into the dorsal ramus and ventral ramus. Spinal nerves are mixed nerves that carry both sensory and motor information.

  8. Ventral nerve cord - Wikipedia

    en.wikipedia.org/wiki/Ventral_nerve_cord

    The ventral nerve cord is a major structure of the invertebrate central nervous system. It is the functional equivalent of the vertebrate spinal cord . [ 2 ] The ventral nerve cord coordinates neural signaling from the brain to the body and vice versa, integrating sensory input and locomotor output. [ 1 ]

  9. Sympathetic trunk - Wikipedia

    en.wikipedia.org/wiki/Sympathetic_trunk

    Function. The sympathetic trunk is a fundamental part of the sympathetic nervous system, ... The formation of the spinal nerve from the dorsal and ventral roots.
