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 |
|
|
