infundibulum

Back 19

stalk of pituitary, connects hypothalamus to pituitary

Front 20

pituitary gland

Back 20

master gland of the body, secretes hormones to control most of our physiology

posterior to thalamus, secretes melatonin to control sleep/awake cycles

Front 22

copora quadrigemina

Back 22

posterior area consisting of 2 superior colliculi (visual reflex actions) and 2 inferior colliculi (auditory reflex actions)
