Dermatomes - Thoracic

Mr. Skin Divisions with Thor-axe
Picmonic
The skin's surface is divided into specific areas called dermatomes, which are mainly supplied by a single spinal nerve. There are 8 cervical nerves (C1 being an exception with no dermatome), 12 thoracic nerves, 5 lumbar nerves and 5 sacral nerves. Each of these nerves relays sensation (and pain) from a particular region of skin to the brain.
