Final answer:
The two major divisions of the ventromedial motor pathway are the corticobulbar tract and the corticospinal tract. The corticobulbar tract targets the brain stem, while the corticospinal tract targets the spinal cord.
Step-by-step explanation:
The two major divisions of the ventromedial motor pathway are the corticobulbar tract and the corticospinal tract. The corticobulbar tract originates in the cortex and targets the brain stem, while the corticospinal tract originates in the cortex and targets the spinal cord. Both tracts are responsible for carrying motor commands from the cortex to control voluntary movements of skeletal muscles. The axons of the corticobulbar tract are ipsilateral, meaning they project to the same side of the nervous system, while the axons of the corticospinal tract are largely contralateral, crossing the midline and synapsing on the opposite side of the body.
