,Hypothalamus
 is a small neural structure situated at the base of the brain
above the optic chiasm and below the third ventricle.
 the hormonal products of this gland are:
 Gonadotrophic releasing hormone (GnRH) - is concerned with the
release of FSH and LH from pituitary.
 Thyrotrophic releasing hormone (TRH)- stimulate the release of TSH
 Corticotrophin releasing hormone (CRH)-stimulate the release of
ACTH
 Growth hormone releasing hormone (GHRH)- stimulate the release
of GH
 Prolactine releasing hormone (PRH)- stimulate the release of
Prolactine
 Prolactine inhibiting factor (PIF)- inhibits the release of prolactine
 Somatostatine - inhibit GH and TSH secretion

, Pituitary
 is suspended from the hypothalamus by
a stalk called infundibrum and is housed
in sela turcica of the sphenoid bone.
 It is composed of two structures:
the amterior lobe also called the adeno
hypophysis and
the posterior lobe also called neuro
hypophysis.
