Document Summary

Spinal cord central cavity surrounded by a gray matter core. External to which is white matter composed of myelinated fiber tracts. Brain similar to spinal cord but with additional areas of gray matter. Cerebellum has gray matter in nuclei and cortex. Cerebrum has nuclei and additional gray matter in the cortex. Arise from the expansion of the lumen of the neural tube. Connected to each other and to the central canal of spinal cord. The ventricles are: the paired c-shaped lateral ventricles, the third ventricle found in the diencephalon, the fourth ventricle, dorsal to the pons. Form the superior part of the brain and make up 83% of its mass. Contain ridges (gyri) and shallow grooves (sulci) Have 3 basic regions cortex, white matter, and basal nuclei. Superficial gray matter, accounts for 40% of the mass of the brain. It enables sensation, communication, memory, understanding, and voluntary movements. Each hemisphere acts contralaterally (controls the opposite side of the body)
