what does the posterior root of a spinal nerve carry?
afferent nerve fibers
dorsal root of spinal nerve









































the dorsal root of spinal nerve (or posterior root of spinal nerve) is one of two "roots" which emerge from the spinal cord. it emerges directly from the spinal cord, and travels to the dorsal root ganglion. nerve fibres with the ventral root then combine to form a spinal nerve. the dorsal root transmits sensory information, forming the afferent sensory root of a spinal nerve.

dorsal ramus of spinal nerve









































the dorsal ramus of spinal nerve (or posterior ramus of spinal nerve, or posterior primary division) 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 sensation to the human back.
