Human Anatomy 3B

March 8th, 2004

The cerebrum is the largest part of the brain. Also, it is the most visible part. It also dominates the adult brain. Most of it is in processing somatic sensory and motor information. Two types of matter are located in the cerebrum. Gray matter is a substance known as the cerebral cortex. It is located in the cerebral nuclei. White matter is deep in the neural cortex and by the cerebral nuclei. Gray matter is the part of the brain that is responsible for processing information. White matter is different. It is responsible for the transmission of information. Areas of gray matter are known as basal ganglia. They are dispersed throughout the white matter. The white matter contains association fibers, commissural fibers, and projection fibers. A coat of neural cortex covers the two hemispheres. Elevated forms of ridges of the brain are called gyri. They are separated by depressions called sulci or fissures. The surface area of the two hemispheres is about two and one half feet. Longitudinal fissures separate the hemispheres. Each hemisphere is divided into lobes. They are like fingerprints, they are all different. On each hemisphere, the central sulcus divides the frontal lobe from the temporal lobe. The primary motor cortex of the gyrus directs voluntary movements. The primary sensory cortex receives somatic sensory information. The general interpretive area receives information from all the sensory association areas. The parieto-occipital sulcus divides the parital lobe from the occipital lobe. Each hemisphere receives sensory information, and sends motor command to the opposite side of the body. They also ...
