Answer:
-The posterior pituitary does not secrete its hormones but acts as an extension of the hypothalamus, storing those hormones.
-The anterior pituitary secretes its hormones (predominantly tropic hormones).
Explanation:
Peptide hormones are usually produced in the body ahead of the time when they will be required. They are usually synthesized in the inactive form and store in the secretory vesicles just under the plasma membrane. Stimulation of the signalling causes immediate release of these hormones into the surrounding medium or the blood. Thus, cellular response to a peptide hormone is always rapid compared to that of the steroid hormone.
