Dermatomal and myotomal assessments
Dermatomes and myotomes both arise from somites, which are divisions of the body of an embryo. Somites are paired structures which run cephalocaudally (along the head to toe axis of the body). In the developing human embryo, somites form dermatomes and myotomes, as well as tendons, cartilage and … See more Adermatome is an area of skin supplied by asingle spinal nerve. If you imagine the human body as a map, each dermatome represents the area of skin supplied with sensation by a specific nerve root.
