Any half of the earth’s surface, but most commonly taken to mean the northern or southern hemisphere, divided by the equator—though in earlier times an equally significant distinction was seen to be that between the eastern (Europe, Asia, Africa) and western (Americas) hemispheres. Climatically, there is a considerable difference between the northern and southern temperate zones, the latter having milder winters for equivalent latitudes due to the greater extent of oceans and the unimpeded circulation of their currents.
Half of a ball-like part; in medicine, half of the lateral half of the cerebrum or cerebellum of the brain.
Disorder of iron metabolism in which iron accumulates in tissues; it is characterized by bronze pigmentation of the skin, an enlarged and impaired liver, diabetes mellitus, and abnormalities of the pancreas and joints. It may be hereditary (idiopathic, or classic, hemochromatosis) or acquired through iron overload from repeated transfusions or intake of iron-containing compounds. Also called bronzed diabetes; iron-storage disease.
One of the two halves of the cerebrum, not in fact hemispherical but more nearly quarter-spherical.
Cerebral hemisphere, referring to either the left or right side of the brain.
