Question

Quizplus · Accepted Answer

The primary motor cortex is located in the frontal lobes, and the one in the left cerebral hemisphere controls skeletal muscles on the right side of the body. Option A is incorrect. Option C is incorrect because other areas of the brain, such as the basal ganglia and cerebellum, are also involved in motor control. Option D is partially correct, as the primary motor cortex does develop motor programs for voluntary movements, but other areas also contribute to this process.
