Quizplus · Accepted Answer

The motor cortex is the part of the brain responsible for voluntary movement, and the amount of brain tissue dedicated to a specific body part typically correlates with the precision and complexity of movements that can be made by that body part. The face has the greatest amount of brain tissue in the motor cortex because it has the most precise movements and control, such as for speech and facial expressions. Arms and trunk also have significant representation in the motor cortex, but not as much as the face. Knees, on the other hand, have a relatively small amount of representation in the motor cortex.
