Cerebral cortex Outer layer of the cerebrum consisting of gray matter, responsible for higher mental function Cortex Bark Thalamus, diencephalon Each of the two gray matter nuclei deep within the brain responsible for relaying sensory information to the cortex Gyri Convolutions (mounds) of the cerebral hemispheres Sulci Shallow grooves that separate gyri Fissures Deep grooves in the brain Cerebellum Portion of the brain located below the occipital lobes of the cerebrum, responsible for control and coordination of skeletal muscles Brainstem Region of the brain that serves as a relay between the cerebrum, cerebellum, and spinal cord; responsible for breathing, heart rate, and body temperature; the three levels are mesencephalon (midbrain), pons, and medulla oblongata Ventricles Series of interconnected cavities within the cerebral hemispheres and brainstem filled with cerebrospinal fluid Cerebrospinal fluid, CSF Plasma clear fluid circulating in and around the brain and spinal cord Spinal cord Column of nervous tissue from the brainstem through the vertebrae, responsible for nerve conduction to and from the brain and body Meninges Three membranes that cover the brain and spinal cord Peripheral nervous, PNS
