Dermatome (anatomy) A dermatome is an area of skin that is mainly supplied by a single spinal nerve. There are eight cervical nerves (C1 being an exception with no dermatome)‚ twelve thoracic nerves‚ five lumbar nerves and five sacral nerves.

The Physiology and Pathophysiology of the Skin Abstract The 5-HT3 receptor is a ligand-gated cation channel located in the central and peripheral nervous system; it has also been detected on a variety of other cells. In the periphery‚ it is found on autonomic neurons and on neurons of the sensory and enteric nervous system. In the CNS‚ the 5-HT3 receptor has been localized in the area postrema‚ nucleus tractus solitarii‚ nucleus vaudatus‚ nucleus accumbens‚ amygdala‚ hippocampus‚ entorhinal‚
