Final answer:
The two indirect outgoing pathways from the motor cortex are the corticobulbar tract and the corticospinal tract, responsible for voluntary movements of skeletal muscles. The corticobulbar tract is ipsilateral, while the corticospinal tract is largely contralateral and involves crossing the body's midline to control muscles on the opposite side.
Step-by-step explanation:
The two types of indirect outgoing pathways from the motor cortex are the corticobulbar tract and the corticospinal tract. These pathways are critical for the conscious or voluntary movements of skeletal muscles. The corticobulbar tract features axons that are ipsilateral, projecting from the cortex to the motor nucleus on the same side, whereas the corticospinal tract axons are largely contralateral, crossing the midline to synapse on the opposite side.These pathways originate in the cortex and have distinct targets; the corticobulbar tract targets the brain stem, and the corticospinal tract targets the spinal cord. The corticospinal tract further descends from the cortex, passes through the internal capsule, cerebral peduncles, and pons, before reaching and traveling through the medulla where the pyramidal decussation occurs. Here, most fibers cross to the opposite side and continue to control different domains of the musculature.
