  1. Myotome

    In vertebrate embryonic development, a myotome is a group of tissues formed from somites. These somites develop into the body wall muscle. Each myotome divides into a dorsal epaxial part and a ventral hypaxial part. The myoblasts from the hypaxial division form the muscles of the thoracic and anterior abdominal walls. The term "myotome" is also used to describe the muscles served by a single nerve root. It is the motor equivalent of a dermatome. Each muscle in the body is supplied by a one or more levels or segments of the spinal cord and by their corresponding spinal nerves. A group of muscles innervated by the motor fibres of a single nerve root is known as a myotome. The epaxial muscle mass loses its segmental character to form the extensor muscles of the neck and trunk of mammals. In fishes, salamanders, caecilians, and reptiles, the body musculature remains segmented as in the embryo, though it often becomes folded and overlapping, with epaxial and hypaxial masses divided into several distinct muscle groups.
