what does the ventral ramus do?
Definition

carries somatic motor fibers to skeletal muscle and sensory fibers from skin

Innervates majority of body wall

Definition

carries somatic muscle fiber to skeletal muscels and sensory fibers from skin

innervates small area of skin/muscle along dorsal midline
