THE HUMAN BRAIN. Your brain uses 20% of your body’s energy, but it makes up only 2% of your body’s weight. Humans have the most complex brain of any animal on earth. Your brain generates 25 watts of power while you’re awake—enough to illuminate a light bulb.

Gray matter is made up of the cell bodies of neurons. White matter is composed of nerve fibers (myelin-coated axons). http://www.nlm.nih.gov/medlineplus/ency/imagepages/18117.htm
FUNCTIONS OF THE PARTS OF THE BRAIN Medulla oblongata: Controls automatic and homeostatic activities: swallowing, vomiting, digestion, breathing, heart activity.
Cerebellum: • Coordinates unconscious functions: balance and movements, hand-eye coordination.
Hypothalamus: Maintain homeostasis, hormones secreted by pituitary, factors to stimulate hormone secretion.
Pituitary gland: • Posterior lobe: store and secretes hormones produced by the hypothalamus. • Anterior lobe: produce and secretes hormones that regulate many body functions.
Cerebral hemispheres: receives impulses from senses, integrating centre for higher complex functions (memory, emotions and consciousness)
