Hyperglycaemia becomes clinically significant once insulin over-secretion can no longer compensate for the degree of insulin resistance. [ 2 ] [ 4 ] [ 1 ] It remains an unsolved question if impaired pancreatic beta cell function or hypersecretion of insulin represent the primary event in the pathogenesis of type 2 diabetes. [ 6 ]
Beta cells (β-cells) are specialized endocrine cells located within the pancreatic islets of Langerhans responsible for the production and release of insulin and amylin. [1] Constituting ~50–70% of cells in human islets, beta cells play a vital role in maintaining blood glucose levels. [2] Problems with beta cells can lead to disorders such ...
The pancreas is an organ of the digestive system and endocrine system of vertebrates. In humans, it is located in the abdomen behind the stomach and functions as a gland. The pancreas is a mixed or heterocrine gland, i.e., it has both an endocrine and a digestive exocrine function. [2] 99% of the pancreas is exocrine and 1% is endocrine.
Endocrinology (from endocrine + -ology) is a branch of biology and medicine dealing with the endocrine system, its diseases, and its specific secretions known as hormones.It is also concerned with the integration of developmental events proliferation, growth, and differentiation, and the psychological or behavioral activities of metabolism, growth and development, tissue function, sleep ...
Secretion of bicarbonate from liver, pancreas and duodenal Brunner's glands. Enhances effects of cholecystokinin Stops production of gastric juice 58 Somatostatin (or growth hormone–inhibiting hormone or growth hormone release–inhibiting hormone or somatotropin release–inhibiting factor or somatotropin release–inhibiting hormone)
In fact, today’s 40- and 50-something women do look and feel different from their mothers at the same age. Old ideas about this life stage are undergoing something of a rebrand.
Gastrinoma causes the over-secretion of the hormone gastrin, resulting in the over-production of acid by the acid-producing cells of the stomach (parietal cells) and a constellation of sequelae known as Zollinger-Ellison syndrome. Zollinger-Ellison syndrome may include severe gastric ulcers, abdominal pain, loss of appetite, chronic diarrhea ...
The gradual growth in sex difference throughout a person's life is a product of various hormones. Testosterone is the major active hormone in male development while estrogen is the dominant female hormone. These hormones are not, however, limited to each sex. Both males and females have both testosterone and estrogen. [109]
