The direct pathway, also known as the pyramidal pathway or corticospinal pathway, is responsible for voluntary control of muscle activity. It originates in the cerebral cortex and travels through the brainstem and spinal cord to synapse with motor neurons that control skeletal muscles. The indirect pathway, on the other hand, is involved in involuntary control of muscle activity and includes several subcortical structures such as the basal ganglia and cerebellum.
