Somatostatin is an inhibitoryendocrine hormone. Many animal tissuecells reduce their activity levels when they bind molecules ofsomatostatin by receptors. Some cells within the hypothalamus ofanimals secrete somatostatin to reduce the activity of some otherhypothalamic endocrine cells. Somatostatin is also released bycells in the pancreatic Islets of Langerhans to control activity ofinsulin and glucagon secreting cells. But the somatostatin releasedin the hypothalamus does not interfere with regulation of Isletcells and somatostatin released in the Islets does not affecthypothalamic cells.

Hypothesize and explain why endocrine release ofsomatostatin from cells in each of these two locations does notinterfere with hormone release from the endocrine cells in theother location.
