Question

Quizplus · Accepted Answer

The pyramidal and corticospinal tracts are the massive motor tracts serving voluntary movement. The extrapyramidal and rubrospinal tracts are involved in involuntary movement and motor coordination, while the supplementary and cerebellar-pontine tracts are involved in motor planning and control. The segmental and nigrostriatal tracts are involved in spinal reflexes and dopamine-mediated movement control, respectively.
