Question

Quizplus · Accepted Answer

The amount of space devoted to each part of the body in the motor cortex is proportional to the complexity and precision of movement of which that part of the body is capable. This is known as the motor homunculus. Therefore, body parts that require more intricate movements (such as the fingers) have more space dedicated to them than larger body parts that are capable of less fine motor movements (such as the torso).
