Dorsal Root Afferents
Ventral Root Efferents
Dorsal roots contain afferent axons that innervate sensory receptors in the periphery. Ventral roots contain efferent axons that innervate skeletal, intrafusal, cardiac & smooth muscle as well as glands in the periphery.
Smooth & cardiac muscle and glands are innervated by sympathetic C fibers from autonomic motoneurons in the lateral horn.
