Question

The ________ innervates the ventrolateral body surface, structures in the body wall, and the limbs.
A) white rami communicantes
B) gray rami communicantes
C) posterior rami
D) anterior rami
E) dermatomes

Accepted Answer

The anterior rami of spinal nerves innervate the ventrolateral body surface, structures in the body wall, and the limbs. The white and gray rami communicantes are associated with the autonomic nervous system, and the posterior rami innervate the skin and muscles of the back. Dermatomes are specific areas of the skin that are innervated by sensory fibers from a single spinal nerve.
