Question

The corpus callosum is composed of
A) arcuate fibers.
B) longitudinal fasciculi.
C) association fibers.
D) commissural fibers.
E) projection fibers.

Accepted Answer

The corpus callosum is a major commissural fiber bundle that connects the two cerebral hemispheres of the brain. Therefore, choice D, commissural fibers, is the best answer. The other choices (arcuate fibers, longitudinal fasciculi, association fibers, and projection fibers) do not accurately describe the composition of the corpus callosum.
