Macromolecules play vital roles within your body. Macromolecules are large molecules within your body that serve essential physiological functions. Encompassing carbohydrates, proteins, lipids and nucleic acids, macromolecules exhibit a number of similarities.
Cerebellum. The cerebellum (infratentorial or back of brain) is located at the back of the head. Its function is to coordinate voluntary muscle movements and to maintain posture, balance, and equilibrium.
So many different structures in the brain are involved in motor functions that some people even say that practically the entire brain contributes to body movements. Though the motor cortex is usually associated with Areas 4 and 6, the control of voluntary movements actually involves almost all areas of the neocortex. 1  The primary motor cortex is the anatomical region composed of Area 4 of the precentral gyrus.
