Question

At which structure are spinal nerves grouped and sorted?
A) A ganglion
B) A nucleus
C) A plexus
D) The cauda equina

Accepted Answer

Spinal nerves are grouped and sorted at plexuses, which are networks of nerves that serve a specific region of the body. The major plexuses are the cervical plexus, brachial plexus, lumbar plexus, and sacral plexus. Ganglia are clusters of nerve cell bodies outside of the central nervous system, nuclei are clusters of nerve cell bodies inside the central nervous system, and the cauda equina is a bundle of nerves that extend past the end of the spinal cord.
