Anterior pituitary
25
It is also known as the neurohypophysis
Posterior pituitary
26
It is the downgrowth of the nervous tissue from the brain
Posterior pituitary
27
This hormone control the uterine contraction during delivery and milk ejection during breastfeeding
Oxytocin
28
This hormone causes water retention and controls the body water balancing mechanism
Antidiuretic hormone
29
This regulates the anterior pituitary
Hypothalamus
30
This regulates the anterior pituitary by producing releasing hormones
Hypothalamus
31
This stimulates the release of anterior pituitary gland hormones and inhibiting hormones
Releasing hormones
32
Hormones control the release of other hormone either by stimulating or inhibiting their release and the function of the hypothalamus. The releasing factor is called
Liberins
32
Hormones control the release of other hormone either by stimulating or inhibiting their release and the function of the hypothalamus. The releasing factor is called
Liberins
32
Hormones control the release of other hormones either by stimulating or inhibiting their release and the function of the hypothalamus. The releasing factors are known as
LIBERINS
32
Hormones control the release of other hormone either by stimulating or inhibiting their release and the function of the hypothalamus. The releasing factor is called
Liberins
32
Hormones control the release of other hormones either by stimulating or inhibiting their release and the function of the hypothalamus. The inhibiting factors are known as
STATINS
33
