The term “dermatome” is a combination of two ancient greek words; “derma” meaning “ skin ”, and “tome”, meaning “cutting” or “thin segment”. it is an area of skin which is innervated by the posterior (dorsal) root of a single spinal nerve. as posterior roots are organized in segments, dermatomes are as well. The trigeminal nerve dermatome map often play an important role in figuring out where the issue is originating from, providing physicians a hint as to where to look for signs of infection, swelling, or injury. typical diseases that may be partially recognized through the dermatome chart include: spinal injury (from a fall, etc.).
Dermatomes. a dermatome is an area of skin supplied by a single 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. it is important to bear in mind that the dermatomes of the head are supplied by branches v1, v2 and v3 of the trigeminal nerve. Dermatomes are areas of skin on your body that rely on specific nerve connections on your spine. in this way, dermatomes are much like a map. the nature of that connection means that dermatomes can help a healthcare provider detect and diagnose conditions or problems affecting your spine, spinal cord or spinal nerves. Dermatomes divide the skin according to sensory nerve distribution (see image. dermatome map). one of the first to map out and discuss the dermatomes is o. foerster in his 1933 publication entitled “the dermatomes in man” in the journal brain. some consider his work the foundation of dermatomal theory.[1] in 1948, j. keegan and f. garrett described spinal nerve distribution in the. The dermatomes of trigeminal nerve typically play an essential function in figuring out where the problem is originating from, giving doctors a hint regarding where to look for indications of infection, swelling, or injury. typical diseases that may be partially identified through the dermatome chart include: spinal injury (from a fall, etc.).

Lumbar spinal nerves. l1: lower back, hips, groin. l2: lower back, front and inside of thigh. l3: lower back, front and inside of thigh. l4: lower back, front of thigh and calf, area of knee. Summary. a dermatome represents the area of skin that provides cutaneous innervation by fibers of a specific nerve. most of the skin on the body is innervated by spinal nerves, but the face receives cutaneous innervation from a cranial nerve (known as the trigeminal nerve). the trigeminal nerve is known as the 5th cranial nerve (cn v) and is.
