Description

The spinal ganglion (dorsal root ganglion or posterior root ganglion) is a sensory ganglion found at the proximal end of the posterior root of each spinal nerve.

The spinal ganglion of the seventh cervical nerve conveys sensory information from the periphery into the dorsal horn of the first cervical spinal segment of the spinal cord.

It contains cell bodies or nuclei of the afferent nerve fibers, which are derived from neural crest cells and comprise pseudounipolar neurons. These afferent neurons convey cutaneous somatic sensory signals, such as touch, temperature and pain, from the skin above the trapezius and the posterior aspect of the upper limb. In addition, visceral sensations from glands and blood vessels from the skin in the same region are also conveyed to the central nervous system.
