Question

The fibers in the corticospinal tract leave the cerebral cortex in the posterior limb of the internal capsule. What is the function of the internal capsule?

1) It carries all axons in and out of the cortex
2) It connects the cerebral cortex to the spinal cord
3) It is responsible for motor control
4) It is involved in sensory processing

Answer 1

The internal capsule carries all axons in and out of the cortex and is responsible for motor control.

Step-by-step explanation:

The function of the internal capsule is to carry all axons in and out of the cortex. It is a bundle of fibers that connects the cerebral cortex to various parts of the brain, including the spinal cord. The fibers in the corticospinal tract leave the cerebral cortex in the posterior limb of the internal capsule, and these fibers are responsible for motor control.
