Detailed explanation-1: -The cerebrum is divided into the left and right hemispheres by a deep longitudinal fissure; the two hemispheres remain in contact and communication with one another by the corpus callosum. Each hemisphere further subdivides into a frontal, parietal, occipital, and temporal lobe.

Detailed explanation-2: -The Equator, or line of 0 degrees latitude, divides the Earth into the Northern and Southern hemispheres. The Northern Hemisphere contains North America, the northern part of South America, Europe, the northern two-thirds of Africa, and most of Asia.

Detailed explanation-3: -The cerebrum (right and left) is the upper, front portion of the brain and consists of two hemispheres, or halves. The two hemispheres are connected by the corpus callosum, which is a large bundle of nerve fibers.

Detailed explanation-4: -The right cerebellar hemisphere is associated with language, and the left cerebellar hemisphere, with visuospatial functions. Executive functions, including verbal working memory, are related to both hemispheres.
