Detailed explanation-1: -The correct answer is E. (motor cortex; frontal). Motor cortex is the brain area dedicated to controlling our voluntary movements. When a part of motor cortex stimulated, it will result in a movement of the body part this exact part of motor cortex is devoted to.
Detailed explanation-2: -The primary motor cortex, shown inFigure 56-1, lies in the first convolution of the frontal lobes anterior to the central sulcus. It begins laterally in the sylvian fissure, spreads superiorly to the uppermost portion of the brain, and then dips deep into the longitudinal fissure.
Detailed explanation-3: -The primary function of the motor cortex is to generate signals to direct the movement of the body. It is part of the frontal lobe and is anterior to the central sulcus. It consists of the primary motor cortex, premotor cortex, and the supplementary motor area.
