brain and cranial nerves
| Question | Answer |
|---|---|
| cerebellar peduncles | white matter tracts connecting cerebellum to brainstem |
| cerebellar peduncles (superior) | connect cerebellum with midbrain, diencephalon, and cerebrum |
| cerebellar peduncles (middle) | connect cerebellum with pons |
| cerebellar peduncles (inferior) | connect cerebellum with medulla oblongata and spinal cord |
| arbor vitae | white matter connecting cerebellar cortex and nuclei with cerebellar peduncles |
| thalamus | relays most sensations to cerebrum |
| interthalamic adhesion | connects two sides of thalamus |
| lateral geniculate nucleus | receives visual information from optic tract |
| medial geniculate nucleus | receives auditory information from inner ear |
| hypothalamus | controls many homeostatic functions |
| preoptic area | regulates body temperature |
| suprachiasmatic nucleus | coordinates day/night cycles of activity |
| mamillary bodies | control feeding reflexes |
| infundibulum | stalk connecting hypothalamus to pituitary gland |
| epithalamus | includes pineal gland (secretes melatonin) |
| limbic system | emotion and memory |
| cingulate gyrus | superior portion |
| parahippocampal gyrus | inferior portion (includes hippocampus, important in storage and retrieval of long-term memories |
| amygdaloid body | important role in linking emotions with specific memories |
| fornix | white matter tract linking hippocampus with hypothalamus |
| basal nuclei | : provide general pattern and rhythm for ongoing voluntary movements |
