Insulin oscillation oscillations. The insulin oscillations are generated by pulsatile release of the hormone from the pancreas. Insulin originates from beta cells located in the islets of Langerhans. Since each islet contains up to 2000 beta cells and there are one million islets in the pancreas it is apparent that pulsatile secretion requires sophisticated synchronization both within and among the islets of Langerhans. Pulsatile insulin secretion from individual beta cells is driven by oscillation of the calcium concentration in the cells. In beta cells lacking contact, the periodicity of these oscillations is rather variable (2-10 min). However, within an islet of Langerhans
Islets of Mauritius this islet was named after the famous volcano on nearby Réunion. It is thought to have broken away from Île D'ambre. Also known as Île aux deux Cocos, the island, located off the southern coast of Grand Port, is named after the two abandoned coconut plantations it houses. The plantations were set up by the French, but were abandoned after crops were damaged during a lengthy storm in the 18th century. Both of these relatively large islands, lying to the east of Mauritius and considered part of Flacq, become temporarily merged at low tide. The islets are an increasingly popular
