  2. Cervical spinal nerve 6 - Wikipedia

    en.wikipedia.org/wiki/Cervical_spinal_nerve_6

    The cervical spinal nerve 6 (C6) is a spinal nerve of the cervical segment. [1]It originates from the spinal column from above the cervical vertebra 6 (C6).. The C6 nerve root shares a common branch from C5, and has a role in innervating many muscles of the rotator cuff and distal arm, [2] including:

  3. Cervical vertebrae - Wikipedia

    en.wikipedia.org/wiki/Cervical_vertebrae

    In humans, cervical vertebrae are the smallest of the true vertebrae and can be readily distinguished from those of the thoracic or lumbar regions by the presence of a foramen (hole) in each transverse process, through which the vertebral artery, vertebral veins, and inferior cervical ganglion pass. The remainder of this article focuses upon ...

  4. Brachial plexus - Wikipedia

    en.wikipedia.org/wiki/Brachial_plexus

    The brachial plexus is a network of nerves (nerve plexus) formed by the anterior rami of the lower four cervical nerves and first thoracic nerve (C5, C6, C7, C8, and T1).This plexus extends from the spinal cord, through the cervicoaxillary canal in the neck, over the first rib, and into the armpit, it supplies afferent and efferent nerve fibers to the chest, shoulder, arm, forearm, and hand.

  5. Nerve plexus - Wikipedia

    en.wikipedia.org/wiki/Nerve_plexus

    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 ...

    The vertebral arteries usually arise from the posterosuperior aspect of the central subclavian arteries on each side of the body, [2] then enter deep to the transverse process at the level of the 6th cervical vertebrae (C6), [1] or occasionally (in 7.5% of cases) at the level of C7.

  9. Middle cervical ganglion - Wikipedia

    en.wikipedia.org/wiki/Middle_cervical_ganglion

    The middle cervical ganglion is presumed to represent the union of the two sympathetic ganglia corresponding to cervical segments C5–C6 since its gray rami communicantes usually join the cervical spinal nerves C5–C6, however, the ganglion sometimes also contributes gray rami communicantes to spinal nerves C4 and C7.
