dermatome[′dər·mə‚tōm] (anatomy) An area of skin delimited by the supply of sensory fibers from a single spinal nerve. (embryology) Lateral portion of an embryonic somite from which the dermis will develop. (medicine) Instrument for cutting skin for grafting. Dermatome cutis plate, the embryonic basis of the connective-tissue part of the skin, or dermis. (The dermis is also formed from some of the cells of the ganglionic plate that develops from the neural columns.) dermatome
dermatome [der´mah-tōm] 1. the area of skin supplied with afferent nerve fibers by a single posterior spinal root.2. the lateral part of an embryonic somite.3. an instrument for removing split-thickness skin grafts from donor sites; there are many different kinds, divided into three major types: knife, drum, and motor-driven.  Dermatomes. Segmental dermatome distribution of spinal nerves to the front, back, and side of the body. C, Cervical segments; T, thoracic segments; L, lumbar segments; S, sacral segments; CX, coccygeal segment. Dermatomes are specific skin surface areas innervated by a single spinal nerve or group of spinal nerves. Dermatome assessment is done to determine the level of spinal anesthesia for surgical procedures and postoperative analgesia when epidural local anesthetics are used. From Thibodeau and Patton, 1999.drum dermatome a dermatome consisting of a cylindrical drumlike apparatus coated with adhesive that rolls over the skin while a blade moves across the surface and cuts the graft free.knife dermatome the simplest type of dermatome, which is used to remove grafts by a freehand technique.motor-driven dermatome a dermatome driven by a power source; motor-driven dermatomes cut with a back-and-forth blade action.der·ma·tome (der'mă-tōm), 1. A power-driven or mechanical instrument used to cut thin sections of epidermis or dermis for grafting, or to excise small lesions. 2. The dorsolateral part of an embryonic somite. Synonym(s): cutis plate3. The area of skin supplied by cutaneous branches of a single cranial or spinal nerve; neighboring dermatomes can overlap. Synonym(s): dermatomal distribution, dermatomic area [dermato- + G. tomē, a cutting] dermatome (dûr′mə-tōm′)n.1. Anatomy An area of skin innervated by sensory fibers from a single spinal nerve.2.

An instrument, mechanical or manual, to shave thin layers of skin for transplantation (grafting).  DERMATOME2. A band or region of skin supplied by a single sensory nerve. See: illustration3. The lateral portion of the somite of an embryo, where the dermis of the skin originates; the cutis plate.dermatome 1. A broad knife for taking very thin skin slices of less than full thickness (split skin) for grafting. 2. The area of skin receiving sensation from a nerve entering a single nerve root of the spinal cord. der·ma·tome (dĕr'mă-tōm) 1. An instrument for cutting thin slices of skin for grafting, or excising small lesions. 2. The dorsolateral part of an embryonic somite.
