Question

impulses conducted along the corticospinal tracts are ____ in nature and control ____
multiple choice
motor, involuntary movements
sensory, perception of pain
sensory, perception of touch
motor, voluntary muscle movements

Explanation:

The corticospinal tracts are motor pathways. They are responsible for voluntary muscle movements. Sensory tracts would be involved in perception (like pain or touch), which rules out the sensory - related options. Involuntary movements are not controlled by the corticospinal tracts. Voluntary muscle movements are the function of the corticospinal tracts as they carry motor commands from the cerebral cortex to the spinal cord.

Answer:

motor; voluntary muscle movements
