MEDICAL PHYSIOLOGY

Detailed explanation-1: -[1] There are three main divisions cerebrum, cerebellum, brain stem. The cerebrum consists of two cerebral hemispheres the outer layer called the cortex (gray matter) and the inner layer (white matter). There are four lobes in the cortex, the frontal lobe, parietal lobe, temporal lobe, occipital lobe.

Detailed explanation-2: -Doctors typically divide the lobes of the brain, or cerebrum, into four distinct regions: the frontal, parietal, occipital, and temporal lobes lobes. Some researchers now also refer to the limbic lobe as a fifth lobe, though most textbooks do not label the limbic lobe as a separate region.

Detailed explanation-3: -Each cerebral hemisphere is divided into five lobes, four of which have the same name as the bone over them: the frontal lobe, the parietal lobe, the occipital lobe, and the temporal lobe. A fifth lobe, the insula or Island of Reil, lies deep within the lateral sulcus.
