A dermatome is an area of skin that is supplied by a single spinal nerve, and a myotome is a group of muscles that a single spinal nerve root innervates. A dermatome is an area of skin that is supplied by a single spinal nerve.

Myotome Chart Pdf - Dermatomes And Myotomes Physical Therapy School Nerve

The body is divided from top to bottom into motor zones described as myotomes. The muscle movement of each myotome is controlled by motor nerves coming from the same motor portion of a spinal nerve root. This differs from a dermatome, which is a zone on the skin in which sensations of touch, pain, temperature, and position are modulated by the same sensory portion of a spinal nerve root. Myotomes and dermatomes are mapped, and the location of sensory or motor deficits correspond to specific nerve roots. Based on your history and physical examination, your doctor or physical therapist can determine the specific nerve root s or spinal core level s that could be causing your problem. Myotomes and dermatomes are part of the peripheral nervous system , and myotomes are part of the somatic voluntary nervous system, which is part of your peripheral nervous system.

They are clinically useful as they can determine if damage has occurred to the spinal cord, and at which level the damage has occurred. In this article we shall look at the embryonic origins of myotomes, their distribution in the adult and their clinical uses. Skeletal muscle development can be traced to the appearance of somites. By day 20 the trilaminar disc has formed and the mesoderm has differentiated into different areas. The area directly adjacent to the neural tube is known as the paraxial mesoderm. From day 20 onwards the paraxial mesoderm begins to differentiate further into segments known as somites.

Andrew J. A sclerotome is an anatomical concept that defines an area of bone supplied by a single spinal nerve. Similar to the familiar dermatomes, sclerotomes provide an element of depth to the sensory innervation of the lower extremity based on the deep fascia as an embryologic boundary. Anatomical knowledge of sclerotomes can be used clinically in the diagnosis and treatment of pain and in the perioperative setting. Specifically, a modified version of the classic Mayo block is presented to highlight an active anatomical approach to peripheral nerve blockade.

In the limbs, sensory fibers are distributed to an area further from the axis of the body than the motor fibers of the corresponding root. The skin innervation areas encroach on each other, which justifies the anesthesia of adjacent nerves.
