Answer 1

Answer:The motor cortex is the region which controls the motor activities. This region is located in the dorsal portion of the frontal lobe of cerebral cortex. This region contains very big and giant pyramidal-shaped neurons. These cells are called as Betz cells. This region plays an important role in the regulation and control of planning, thinking and other voluntary activities. This region is involved in the thoughts processing. The region is important for decision making and performing voluntary movements including the bones and muscles. Thus, the correct answer is option D.
