 Main regions of the brain | Cerebral hemispheres, diencephalon, brain stem structures, cerebellum |
| Largest part of the brain | Cerebral hemispheres |
| Make-up of cerebral hemispheres | Surface( cortex) is gray matter, interior is white matter with islands of gray metter (basal nuclei) |
| Cerebral hemispheres are separated by... | the longitudinal fissure |
| Functions of cerebral cortex | Speech, memory, logical and emotional response, consciousness, interpretation of sensation, voluntary muscle activity |
| Parkinson's and Huntington's are disorders of... | the basal nuclei |
| Promary motor area is in... | the frontal lobe |
| Cerebral white matter is composed of... | fiber tracts carrying impulses |
| Corpus callosum | Large fiber tract connecting the cerebral hemispheres |
| Role of basal nuclei | Regulate voluntary motor activities by modifying instructions sent to skeletal miscles |
| Location of diencephalon | On top of brain stem, enclosed by cerebral hemispheres |
| Major structures of diencephalon | 1. Thalamus 2. Hypothalamus 3. Epithalamus |
| Role of thalamus | Relay station for sensory impulses passing upward to sensory cortex |
| Role of hypothalamus | Regulates water balance, metabolism, thirst, temperature; also regulates pituitary gland |
| Ventricles | the two lower chambers of the heart |
| Structures of epithalamus | Pineal gland and choroid plexus of third ventricle |
| Choroid plexuses form... | cerebrospinal fluid |
| Brain stem location | Inferior to the hypothalamus, merges with spinal cord |
| Structures of brain stem | Midbrain, pons, medulla oblongataa |
