• White ramus (myelinated axons)• Gray ramus (unmyelinated axons that innervate glands and
smooth muscle)• Dorsal ramus (sensory and motor innervation to the skin and
muscles of the back)• Ventral ramus (supplying ventrolateral body surface, body wall
and limbs)• Each pair of nerves monitors one dermatome
