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 and skerries in the Faroes to the fact that Sumbiarsteinur is lying to itself, while the other skerries are close together. This group of skerries are called Flesjarnar. Munkurin is the southernmost point of the Faroes at 61° 10' 30".85 N, 6° 40' 23".77 W. Flesjarnar can be seen from Sumba, Akraberg and from Eggjarnar and other high places in Suðuroy. Islets and skerries in the Faroes Besides the 18 islands of the Faroes there are also several islets and skerries. The Faroe Islands consist of 779 islands, islets and skerries. The islets are small and are geographical parts of the larger islands. Suðuroy consists
