Question

The _______ consists of efferent (motor) fibers leaving the spinal cord.
A) ventral root
B) spinal ganglion
C) dorsal root
D) afferent root

Accepted Answer

The ventral root of the spinal cord contains efferent (motor) fibers that leave the spinal cord to innervate muscles and organs. The dorsal root contains afferent (sensory) fibers that transmit information from the periphery to the spinal cord. The spinal ganglion contains the cell bodies of sensory neurons. There is no such thing as an afferent root.
