How is it basically structured: spinal cord forebrain. Structure of the human brain: lobes of the cerebral cortex. Blood supply of the brain: strokes, tumors. Human brain: gyri mountains, sulci fissures. Human brains separated into left and right hemispheres: mirror images, not exactly alike slight differences. Right brain (hemisphere: controls and receives information from left side of the body. Left brain (hemisphere: controls and receives information from right side of the body. Corresponding on the opposite side of the body. Three main sulci: longitudinal fissure divides the two hemispheres. Separates frontal and parietal lobes: sylvian fissure. Fore lobes in general: frontal lobe, parietal lobe, temporal lobe, occipital lobe. Each lobe has one major primary function. Each lobe has two different types of cortex: primary. Responsible for performing basic input / output function. Area that is responsible the primary function of the specific lobe: associational. Primary area of motor control: brodmann areas 4 and 6.
