Insulin secretion is modified by other nutrients, circulating hormones and the autonomic nervous system, as well as local paracrine and autocrine signals. Autocrine signalling involves diffusible molecules that bind to receptors on the same cell from which they have been released.
One of the most important Calcium containing hormone is Insulin. Insulin is always secreted to control sugar quantity in the blood stream by adequately dissolving sugars. When insulin secretion is abnormal, diabetes results. Insulin is secreted from B (beta) cells in the islet of Langerhans in the pancreas. Ionic or plasma Calcium plays an important role in insulin secretion in these cells. If Calcium in the exterior fluid surrounding these cells is removed or if the calcium channels are blocked, insulin secretion is also blocked.
