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
Two Superior colliculi & two inferior colliculi
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.
Conducts CSF from third ventricle to fourth ventricle
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.
Connects hypothalamus with pituitary gland.
Is commissural tracts that connect left and right hemispheres of the cerebrum
Thin wall that separates the two lateral ventricles.
Responsible for subconscious control of skeletal muscle tone, plus coordinate learned muscle movement patterns
Process sensory information plus control reflex movements associated with eating.
Secretes melatonin, which regulates day-night cycles & reproductive cycles.
The Five Lobes of the Cerebrum
Frontal lobe ; Parietal lobe; Occipital lobe; Temporal lobe; Insula
Connections within a hemisphere
Connections between hemispheres
Connections with other parts of the brain or spinal cord
