  • Somite Development

    • They will eventually become dermis (dermatome), skeletal muscle (myotome), vertebrae (sclerotome), and tendons and cartilage (syndetome).
    • The myotome is that part of a somite that forms the muscles.
    • Each myotome divides into an epaxial part (epimere), at the back, and a hypaxial part (hypomere) at the front.

  • Spinal Cord Trauma

    • A group of muscles innervated through a specific part of the spine is called a myotome, and injury to the spine can cause problems with voluntary motor control.
