hypo's control of ant pit
1.releasing and inhibiting H's of its own

2.H's are carried to ant pit's capillary bed via portal (blood) vessels
anterior pit H's
all H's are PEPTIDES:
1.hGH
2.ACTH
3.TSH
4.FSH
5.LH
6.prolactin (- effect of hypo)
posterior pit H's
all H's are PEPTIDES:
1.oxytocin
2.ADH (vasopressin)
hypo's action on post pit
1.synthesized in neural cell bodies of HYPO
2.transported to POST PIT
3.released directly from here
