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.
The pre-motor area takes the incoming sensory information needed for the body movements, and the supplementary motor area plans the complex movements. The motor cortex is not the only area of the brain responsible for voluntary movementsâthe prefrontal cortex and the posterior parietal cortex are also involved.
