Question

Quizplus · Accepted Answer

The corticospinal pathway is responsible for voluntary control of skeletal muscles. It originates in the motor cortex of the brain and travels down the spinal cord to synapse with motor neurons that directly control the muscles. The other choices (posterior column, medial pathway, spinothalamic pathway, medullary centers) are involved in other functions such as proprioception, pain and temperature sensation, and autonomic regulation.
