Shearing of axons in a diffuse axonal injury causes such widespread disruptions because such an injury involves
A) association fibers.
B) commissural fibers.
C) projection fibers.
D) pyramidal tract fibers.

Question

Quizplus · Accepted Answer

Diffuse axonal injury involves the shearing or tearing of the axons of projection fibers, which are long axons that connect different regions of the brain and spinal cord. These disruptions can lead to widespread damage and dysfunction throughout the neural network. Association fibers connect adjacent regions within the same hemisphere, commissural fibers connect corresponding regions in the two hemispheres, and pyramidal tract fibers are a type of projection fiber that are involved in motor control.
