Two terms for the massive motor tracts serving voluntary movement are ________.

Question

Quizplus · Accepted Answer

The terms pyramidal and corticospinal both refer to the massive motor tracts that originate in the cerebral cortex and descend through the brainstem and spinal cord, ultimately controlling voluntary movement. Extrapyramidal and rubrospinal refer to other motor pathways that are involved in movement but are not as directly involved in voluntary movement as the pyramidal/corticospinal tracts. Segmental and nigrostriatal also refer to other motor pathways but are not specifically related to voluntary movement. Supplementary and cerebellar-pontine are also motor-related terms but do not specifically refer to the massive motor tracts serving voluntary movement.
