Medicine is the branch of health science and the sector of public life concerned with maintaining or restoring human health through the study, diagnosis and treatment of disease and injury. It is both an area of knowledge — a science of body systems, their diseases and treatment — and the applied practice — an art or craft — of that knowledge. However, medicine often refers more specifically to matters dealt with by physicians and surgeons.

The term "medicine" is sometimes used amongst medical professionals as shorthand for internal medicine. Veterinary medicine is the practice of health care in animal species other than human beings. Please see our medical disclaimer for cautions about Wikipedia's limitations.

Selected article

The Cerebellum.
The cerebellum (Latin: "little brain") is a region of the brain that plays an important role in the integration of sensory perception and motor output. Many neural pathways link the cerebellum with the motor cortex—which sends information to the muscles causing them to move—and the spinocerebellar tract—which provides feedback on the position of the body in space (proprioception). The cerebellum integrates these pathways, using the constant feedback on body position to fine-tune motor movements.

Because of this 'updating' function of the cerebellum, lesions within it are not so debilitating as to cause paralysis, but rather present as feedback deficits resulting in disorders in fine movement, equilibrium, posture, and motor learning. Initial observations by physiologists during the 18th century indicated that patients with cerebellar damage show problems with motor coordination and movement. Research into cerebellar function during the early to mid 19th century was done via lesion and ablation studies in animals. Research physiologists noted that such lesions led to animals with strange movements, awkward gait, and muscular weakness. These observations and studies led to the conclusion that the cerebellum was a motor control structure. However, modern research shows that the cerebellum has a broader role in a number of key cognitive functions, including attention and the processing of language, music, and other sensory temporal stimuli.

A child is prepared for polysomnography (PSG). Polysomnography is a comprehensive recording of the biophysiological changes that occur during sleep. The PSG monitors many body functions including brain (Electroencephalography), eye movements (Electrooculography), muscle activity or skeletal muscle activation (Electromyography), heart rhythm (electrocardiogram), and breathing function or respiratory effort during sleep.
