| Brain stem | made of medulla, pons, and midbrain |
| This goes through the brain stem | a route for ascending and descending tracts |
| Name the ventricles | 4 total - 2 lateral, 1 third, and 1 fourth |
| choroid plexus | a rich network of blood vessels which forms CSF |
| CSF is specifically formed from this | blood plasma |
| Function of medulla | vital functions; HR, BP, RR (less vital functions, coughing, sneezing, swallowing, vomiting) |
| Function of pons | connects medulla with other parts of brain; helps medulla with breathing |
| Functions of midbrain | visual and auditory reflexes; balance and equilibrium ("the righting reflex") |
| Functions of the cerebellum | movement; coordination, muscle tone, controlled start and stop movements, maintenance of posture and equilibrium |
| Diencephalon consists of these | hypothalamus and thalamus |
| ADH | made in hypothalamus; it tells the kidneys to reabsorb water when needed |
| oxytocin | made in hypothalamus; tells uterus to contract |
| Hypothalamus produces these to tell hormones to go to work | releasing hormones |
| Hypothalamus promotes this to regulate body temperature | sweating or shivering |
| Hypothalamus regulates food intake this way | lateral portion has the feeding center that is stimulated by hunger |
| Hypothalamus does this in response to emotional situations | stimulates visceral responses like increased heart rate, diarrhea, etc |
| circadian rhythm | combination of hormone secretion, sleep cycles, and changes in mood or mental alertness |
| Thalamus functions | concerned with sensations; sorts them out and sends them to cerebrum |
| Thalamus can do this with sensations if needed | suppress them |
| Damage to the thalamus can do this | create total loss of consciousness |
