Geography of the brain: contralateral, structures on opposite side of the body (e. g. left cerebral cortex controls movement of the contralateral hand means that it controls movement of the. It has a weblike appearance: the third layer that sits closest to the brain in the pia mater which comprises blood vessels, the arachnoid space between is filled with csf. Anatomical divisions of the brain: brain is composed of five major divisions, different swellings of the neural tube represent different phases of embryological development, early development of the brain, the 5 major divisions of the adult brain: The forebrain: cerebral cortex: the cerebral cortex is highly convoluted with sulci (small grooves), fissures (large or major grooves and gyri (ridges between sulci or fissures). The convolu- tions increase the surface area of the cortex: the cerebral cortex consists mainly of glial cells, axons, dendrites and a high con- centration of cell bodies.
