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: Subclavius; Supraspinatus; Infraspinatus ...
A nerve root (Latin: radix nervi) is the initial segment of a nerve leaving the central nervous system.Nerve roots can be classified as: Cranial nerve roots: the initial or proximal segment of one of the twelve pairs of cranial nerves leaving the central nervous system from the brain stem or the highest levels of the spinal cord.
This nerve is involved (together with nerve IX) in the pharyngeal reflex or gag reflex. XI Accessory. Sometimes: cranial accessory, spinal accessory. Mainly motor Cranial and Spinal Roots Located in the jugular foramen. Controls the sternocleidomastoid and trapezius muscles, and overlaps with functions of the vagus nerve (CN X). Symptoms of ...
The muscles that one particular spinal root supplies are that nerve's myotome, and the dermatomes are the areas of sensory innervation on the skin for each spinal nerve. Lesions of one or more nerve roots result in typical patterns of neurologic defects ( muscle weakness , abnormal sensation, changes in reflexes) that allow localization of the ...

The axons which form the upper subscapular nerve travel from the ventral rami of C5 and C6. [1] They join at the upper trunk and move through its posterior division to form the posterior cord, along with the other two posterior divisions of the middle and lower trunks. [1] The axons then branch from the posterior cord and form the upper ...
