Document Summary

Endocrine pancreas contains islets of langerhans (important for hormonal regulation) which produces insulin, glucagon, somatostatin and pancreatic polypeptides. The pancreas is associated with cellular nutrition and the balancing of glucose levels. If this fails you suffer from diabetes mellitus. This was the first endocrine disorder noted in history. Before you could treat it with insulin, diabetes was fatal. B cells in the islets of langerhans produce insulin (45 units of insulin per day). Diabetes type ii little or insufficient production and high tissue insulin resistance. Consists of the adrenal cortex (cortisol, aldosterone, androgens, estrogens) and the adrenal medulla (adrenaline, noradrenaline, dopamine, enkephalins). Adrenal insufficiency associated with metabolic effects of the hormones of the adrenal glands. Hypo activity is linked to weakness, fatigue, nausea, weight loss, low blood pressure. Hyperactivity is linked to obesity and high blood pressure. Two distinct systems (male/female) regulated by fsh and lh from the pituitary.
