Corticospinal axons mostly:

A. Send ipsilateral axons into the lateral corticospinal tract.

B. Send contralateral axons into the ventral (anterior) corticospinal tract.

C. Synapse onto spinal α motor neurons.

D. Synapse onto spinal local circuit neurons.

E. Synapse onto spinal γ motor neurons.

Corticospinal axons are responsible for carrying signals from the cerebral cortex to the spinal cord. They are a part of the pyramidal tract. These axons are divided into two main groups: the lateral corticospinal tract and the ventral (anterior) corticospinal tract.

The majority of corticospinal axons send ipsilateral (same-sided) axons into the lateral corticospinal tract. This means that the axons from one side of the brain travel to the same side of the spinal cord. The lateral corticospinal tract is responsible for voluntary movements of limbs and fine motor control.
