Document Summary

Between c7 and c8: empty spot where c8 nerve passes hole created by two vertebrae stacked on each other inferior vertebral notch matched with a superior vertebral notch root coming off anterior side is ventral root dorsal root ganglia swelling of cell bodies nerves exit spinal cord via ventral root (motor neurons) nerves enter spinal cord via dorsal root (sensory neurons) Root(cid:224) nerve (cid:224) rami autonomic nervous system segmental sensory information dermatome map all spinal levels correspond to specific level of body latent within dorsal root ganglia suppressed. When older, virus can become reactivated when immunocompromised infects spinal nerve associated with dorsal root ganglia that it was dormant in infection within sensory neurons infects level of dermatome pain and tingling braid of nerves that supply the arms neck and axilla region axilla armpit area runs through this region spinal roots coming from vertebral level combine and reorganize themselves terminal branches that go to muscles in arm.
