Tight junctions between endothelial cells of capillary walls that regulate which substances can leave the blood and enter the brain
Special ependymal cells with tight junctions located in the choroid plexuses in the brain ventricles
Contains cardiac, vasomotor & respiratory control centers, plus all connecting tracts between brain & spinal cord
Includes tracts that connect cerebrum to the cerebellum, medulla & spinal cord. Includes some respiratory control centers
Adjusts postural muscles (maintains balance & equilibrium) plus programs & fine tunes learned movement patterns
Contain descending fibers that go to the cerebellum or carry voluntary motor commands from the cerebral hemispheres
Function in tracking moving objects, and reflexes of blinking, focusing & pupillary muscle actions. Also control the reflex movements of the eyes, head & neck in response to visual stimuli.
Control movements of head, neck, & trunk in response to auditory stimuli, like a loud noise.
Acts as a relay station for all sensory input to the cerebral cortex (except olfactory) and also provides feedback loops between cerebral cortex basal nuclei.
Controls autonomic functions, regulates pituitary gland, produces hormones, regulates body temp, controls food & water intake, regulates sleep.
Responsible for subconscious control of skeletal muscle tone, plus coordinate learned muscle movement patterns
