In
vertebrate embryonic development, a 'myotome' is a group of tissues formed from
somites that develop into the body wall muscle.
Each myotome divides into a
dorsal epaxial part and a
ventral hypaxial part.
The epaxial muscle mass loses its segmental character to form the
extensor muscles of the neck and trunk.
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 cranial nerve.
[1] It is the motor equivalent of a
dermatome.
