GROSS ANATOMY

Detailed explanation-1: -Your cerebral cortex is the outermost layer of your brain. Its surface has many folds, giving it a wrinkled appearance. The folds consist of many deep grooves called sulci and raised areas called gyri.

Detailed explanation-2: -The cerebral cortex appears grayish brown in color and is called the “gray matter.” The surface of the brain appears wrinkled. The cerebral cortex has sulci (small grooves), fissures (larger grooves) and bulges between the grooves called gyri.

Detailed explanation-3: -The cerebral cortex is a sheet of neural tissue that is outermost to the cerebrum of the mammalian brain. It has up to six layers of nerve cells. It is covered by the meninges and often referred to as grey matter.

Detailed explanation-4: -Beginning in utero and up until the first two years of age, the cortex of the brain expands. As this occurs, the brain will bend or buckle, creating folds.

Detailed explanation-5: -Thalamus: The thalamus is the relay center of the brain. It receives afferent impulses from sensory receptors located throughout the body and processes the information for distribution to the appropriate cortical area.
