Which brain lobe is described as controlling movement on the contralateral side of the body?

• A. Frontal
• B. Temporal
• C. Occipital
• D. Insula

Answer: (A)

Movement is governed by the frontal lobe, which houses the primary motor cortex in the precentral gyrus. Neurons here send commands down the corticospinal tract to the spinal cord, and most fibers cross to the opposite side as they descend. This crossing means each hemisphere controls the opposite side of the body, so the frontal lobe is responsible for contralateral motor control. The temporal lobe handles hearing and memory, the occipital lobe processes vision, and the insula is involved in gustation and internal state regulation, not voluntary movement.
