Dorsal Rami

The dorsal ramus of spinal nerve is the posterior division of a spinal nerve. The dorsal ramus (Latin for branch, plural rami) is the dorsal branch of a spinal nerve that forms from the dorsal root of the nerve after it emerges from the spinal cord. The spinal nerve is formed from the dorsal and ventral rami. The dorsal ramus carries information that supplies muscles and skin sensation to the human back.

This nerve arises from the Spinial Cord.
