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.
Brain Motor Areas. The areas of the brain that control both gross and fine motor skills include the cerebral cortex, basal ganglia, and cerebellum. The cerebral cortex controls the movements of the muscles. The basal ganglia control position and voluntary movement. The cerebellum monitors muscles during movement.
