Answer 2

A myotome is the group of muscles that a single spinal nerve root innervates. Similarly a dermatome is an area of skin that a single nerve innervates. In vertebrate embryonic development, a myotome is a group of tissues formed from somites. These somites develop into the body wall muscle.
