Definition | Term |
---|---|
functions include speech, memory, logical & emotional response, consciousness, interpretation of sensation & voluntary movement | cortex |
composed of fiber tracts carrying impulses to, from, or within the cortex | white matter |
help regulate voluntary motor activity | basal nuclei (ganglia) |
serves as relay station for sensory impulses passing upward to sensory cortex; impulses surge through thalamus; pleasant or unpleasant; transfers impulses to correct part of cortex for localization & interpretation | thalamus |
under thalamus; autonomic nervous system center; houses limbic center for emotion; regulates nearby pituitary gland; houses mammillary body for olfaction | hypothalamus |
houses pineal body; includes choroid plexus which forms cerebrospinal fluid | epithalamus |
composed mostly of tracts of nerve fibers; 4 rounded protrusions called corpora quadrigemina are reflex centers involved with vision & hearing | midbrain |
bulging center part of brain stem; composed of fiber tracts; includes nuclei involved in control of breathing | pons |
lowest part of brain stem; merges into spinal cord; important fiber tracts; important control centers | medulla oblongata |
2 hemispheres, right & left; controls balance & equilibrium; provides precise time for skeletal muscle activity & coordination of body movements | cerebellum |
paired (left & right) superior parts of the brain | cerebral hemisphere |
sits on top of the brain stem; enclosed by the cerebral hemispheres | diencephalon |
attaches to spinal cord | brain stem |
