AP PSYCHOLOGY

Detailed explanation-1: -Cerebellum. This is the back of the brain. It coordinates voluntary muscle movements and helps to maintain posture, balance, and equilibrium.

Detailed explanation-2: -Coordination of voluntary movements. Most movements are composed of a number of different muscle groups acting together in a temporally coordinated fashion. One major function of the cerebellum is to coordinate the timing and force of these different muscle groups to produce fluid limb or body movements.

Detailed explanation-3: -The cerebellum-also called the “little brain” because it looks like a small version of the cerebrum-is responsible for balance, movement, and coordination. The pons and the medulla, along with the midbrain, are often called the brainstem. The brainstem takes in, sends out, and coordinates the brain’s messages.

Detailed explanation-4: -Instead-like the basal ganglia-the cerebellum influences movements by modifying the activity patterns of the upper motor neurons. In fact, the cerebellum sends prominent projections to virtually all upper motor neurons.

Detailed explanation-5: -There are three functional areas of the cerebellum – the cerebrocerebellum, the spinocerebellum and the vestibulocerebellum. Cerebrocerebellum – the largest division, formed by the lateral hemispheres. It is involved in planning movements and motor learning.
