Spinal nerve - Wikipedia, the free encyclopedia (619 words)
The term spinal nerve generally refers to the mixed spinal nerve, which is formed from the dorsal and ventral roots that come out of the spinal cord.
After the dorsal and ventral roots fuse to form a spinal nerve, the nerve bifurcates into dorsal and ventral primary rami.
The muscles that one particular spinal root supplies are that nerveĀ“s myotome, and the dermatomes are the areas of sensory innervation on the skin for each spinal nerve.
