Question

Quizplus · Accepted Answer

Upper motor neurons do not directly innervate muscles; instead, they influence and modify spinal reflex arcs. The cell bodies of upper motor neurons are typically located in the cerebral cortex or brainstem, outside of the gray matter of the spinal cord. The dendritic processes of upper motor neurons extend within the CNS.
