Myotome

This article is about anatomical myotomes. For myotomes in developmental biology and embryology, see Myotome (embryology).

A myotome is the group of muscles that a single spinal nerve innervates.[1] Similarly a dermatome is an area of skin that a single nerve innervates with sensory fibers. Myotomes are separated by myosepta (singular: myoseptum).[2] In vertebrate embryonic development, a myotome is the part of a somite that develops into muscle.
