posterior pituitary (PP) is also called?
|
nuerohypophysis
|
|

what is the function of the PP?
|
to store and release hormones made by the hypothalamus.
these 2 hormones are? |
oxytocin- OT
antidiuretic- ADH |

oxytocin- OT
which is produced by the hypothalamus and stored and released by the? |
Posterior pituitary gland

what hormone decreases urine production by causing the kidneys to return more water to the blood?
|
antidiuretic- ADH
which is produced by the hypothalamus and stored and released by the? |
PP
|
