| CRANIAL NERVE FOR HYPOGLOSSAL: | XII:TWELVE |
| An autonomic reflex center involved in maintaining body homeostasis (cardiovascular center, respiratory centers, centers for sneezing, vomiting, hiccupping, swallowing, coughing) | Medulla oblongata |
| Contains the pneumotaxic center to maintain the normal rhythm of breathing | Pons |
| Controls visual reflexes that coordinate head and eye movements when we follow a moving object | Midbrain |
| Associated with the pineal gland, secretes melatonin to induce sleep | Epithalamus |
| The main visceral control center of the body responsible for maintaining homeostasis | Hypothalamus |
| Sorts and "edits" information from sensory areas ascending to the cerebral cortex | Thalamus |
| Receives information from the general sensory receptors in the skin and from proprioceptors in skeletal muscles | Primary somatosensory cortex |
| Integrates sensory inputs (temperature, pressure, etc.) relayed to it to produce an understanding of an object being felt | Somatosensory association cortex |
| Involved in the perception of taste stimuli | Gustatory cortex |
| Important in starting, stopping, and monitoring the intensity of movements executed by the cortex | Basal nuclei |
| Enter the cerebral hemispheres from lower brain or cord centers, and those that leave the cortex to travel to lower areas | Projection fibers |
| Neuron cell bodies | Gray matter |
| Groups of axons in the CNS | White matter |
| Shortage of ACh and structural changes in the brain | Alzheimer's disease |
| Degeneration of dopamine-producing cells in the basal nuclei | Parkinson's disease |
| Seen during deep sleep, during anesthesia; indicate brain damage in awake adults | Delta waves |
| Common in children; abnormal in awake adults | Theta waves |
| Occur when we are mentally alert, as when concentrating on some problem or visual stimulus | Beta waves |
| Indicate a brain that is "idling", a calm, relaxed state of wakefulness | Alpha waves |
