Human digestive system gland in the digestive system. It is both an endocrine gland and an exocrine gland. The endocrine part secretes insulin when the blood sugar becomes high; insulin moves glucose from the blood into the muscles and other tissues for use as energy. The endocrine part releases glucagon when the blood sugar is low; glucagon allows stored sugar to be broken down into glucose by the liver in order to re-balance the sugar levels. The pancreas produces and releases important digestive enzymes in the pancreatic juice that it delivers to the duodenum. The pancreas lies below and at the back of
Brockmann body inhibiting glucagon. Somatostatin released from Brockmann body inhibits cells to produce insulin and glucagon. In addition it inhibits release of growth hormone from the pituitary. It is named after a German physician Heinrich Brochmann who discovered it in 1848. Brochmann body has gained a new attention in medical research, specifically in the management of type I diabetes mellitus. This is because the tissue is easy to harvest, and its insulin can be easily extracted. In addition, the teleost fishes can regenerate their endocrine tissues after harvest, the property of which has challenging implication in human diabetes. A typical Brochmann body
