What Is The Difference Between Dermatomes And Peripheral Nerves The term “ dermatome ” is a combination of two greek words; “derma” meaning “skin”, and “tome”, meaning “cutting” or “thin segment”. dermatomes are areas of the skin whose sensory distribution is innervated by the afferent nerve fibres from the dorsal root of a specific single spinal nerve root, which is that portion of. 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.

Paresthesia Tingling And Numbness Causes And Treatment The receptive field of a peripheral sensory nerve (peripheral nerve field) crosses over different dermatomes. a dermatome is an area of skin supplied by a single spinal nerve. therefore, the map of peripheral nerve fields over the body differs from the dermatomal distribution since individual peripheral nerves are composed of multiple nerve roots. Dermatomes are valuable in localizing neurologic deficits. for example, sciatica is a neuropathy involving the sciatic nerve (l4 s3) and its associations. symptoms like pain and tingling follow a dermatomal distribution, which, for the sciatic nerve, starts from the posterior hip and descends to the posterior aspect of the lower extremity. Peripheral neuropathies can be generally classified into either mononeuropathy if a single peripheral nerve is affected, or polyneuropathy if multiple peripheral nerves are affected. mononeuropathies and polyneuropathies can affect cutaneous sensory, motor and autonomic nerve fibers or a combination of these nerve types, and thereby elicit. In the absence of traumatic injury, initial treatment of nerve injuries should be conservative and includes patient education, relative rest, and activity modification. 13 – 22, 29 – 31, 33.
