Detailed explanation-1: -A dermatome is an area of skin supplied by a single spinal nerve. There are 31 pairs of spinal nerves, forming nerve roots that branch from your spinal cord. Your spinal nerves help to relay sensory, motor, and autonomic information between the rest of your body and your central nervous system (CNS).
Detailed explanation-2: -A dermatome is an area of skin that is mainly supplied by a single spinal nerve. There are 8 cervical nerves (note C1 has with no dermatome), 12 thoracic nerves, 5 lumbar nerves and 5 sacral nerves. Each of these spinal nerves relay sensation from a particular region of the skin to the brain.
Detailed explanation-3: -A dermatome is an area of skin supplied by sensory neurons that arise from a spinal nerve ganglion.
Detailed explanation-4: -A dermatome is an area on your body that relies on a specific spinal nerve. That spinal nerve is critical for its dermatome because it carries all the nerve signals traveling between the dermatome and your brain.
