A member asked:

What is the difference between dermatome and peripheral nerve innervations? which of them carry pain and temperature sensations?

A doctor has provided 1 answer

Definitions overlap: A dermatome is an area of skin supplied by sensory neurons that arise from a single spinal nerve ganglion (from a single dorsal root). A peripheral nerve field refers to an area of skin innervated by a single nerve. An area innervated by a single dorsal root is called a dermatome. Both can sense pain and temperature.
