- apetite-like drives and behaviors (i.e. sex, thirst, hunger)
- emotions (with limbic sys)
- integrates with endocrine system
- circadian rhythms
- body temp
- modifies respiratory reflexes
supraoptic nucleus function
secretes ANTIDIURETIC hormone (restricts water loss at kidneys)
suprachiasmatic nucleus fxn
regulates CIRCADIAN rhythms
paraventricular nucleus fxn
secretes OXYTOCIN (smooth muscle contractions in uterus and mammary glands)
tuberal area fxn
produces INHIBITORY and RELEASING hormones that control the ANTERIOR lobe of pituitary
autonomic centers fxn
- control heart rate and blood pressure via medulla
mamillary bodies fxn
control feeding reflexes (i.e. licking, swallowing etc.)
