dorsal root of the spinal nerve
the afferent sensory root and carries sensory info to the brain. its cell bodies lie in a ganglion outside the spinal cord
ventral root of the spinal nerve
the efferent motor root and carries motor info from the brain. its cell bodies lie in the ventral horn of the spinal cord
spinal nerve
made of a dorsal and ventral root that carries both sensory and motor neurons. the spinal nerve then splits into multiple branches that spread outward to connect with various body structures
