Where do the axons that enter the cortico-spinal tract originate? (The complete answer should include more than one of Brodmann’s areas.)

From the main motor cortex, Brodmann region 4 premotor areas and the primary somatosensory cortex .

Explanation:

The corticospinal tract originates in many regions of the brain, including

The corticospinal tract allows for voluntary control of motor functions.

30% of the neurons in the corticospinal regions are found in the primary motor cortex. 40% are split up in several regions; the parietal lobe, somatosensory cortex and the cingulate gyrus.

The axon is a tube enclosed in and insulated by the myelin sheath. It serves as a link to impulses for certain neurons that often comprise axon hillocks that are junctions between the axon and the cell body.
