    Another one of these details can be noted in insulins secretory granules, or container like buds, that store insulin within a cell. In PP cells, the size of the insulin granules are smaller and spherical and similar to those in alpha cells. This is noted in human PP cells, but different animals have been shown to have different sized granules ...

    Immunohistochemistry for pancreatic polypeptide in a mouse pancreas, 200×. Pancreatic polypeptide (PP) is a polypeptide secreted by PP cells in the endocrine pancreas.It is a hormone and it regulates pancreatic secretion activities, and also impacts liver glycogen storage and gastrointestinal secretion.

    They give rise to both the endocrine and exocrine cells. Exocrine cells constitute the acinar cells and the ductal cells. The endocrine cells constitute the beta cells which make insulin, alpha cells which secrete glucagon, delta cells which secrete somatostatin and the PP-cells which secrete pancreatic polypeptide.

    There are about 1 million islets distributed throughout the pancreas of a healthy adult human. While islets vary in size, the average diameter is about 0.2 mm. [5]:928 Each islet is separated from the surrounding pancreatic tissue by a thin, fibrous, connective tissue capsule which is continuous with the fibrous connective tissue that is interwoven throughout the rest of the pancreas.

    Pancreas contain nearly 1 to 2 million islets of Langerhans (a tissue which consists cells that secrete hormones) and acini. Acini secretes digestive enzymes. [9] Alpha cells. The alpha cells of the pancreas secrete hormones to maintain homeostatic blood sugar. Insulin is produced and excreted to lower blood sugar to normal levels.

    5-DHT or DHT is a male reproductive hormone that targets the prostate gland, bulbourethral gland, seminal vesicles, penis and scrotum and promotes growth/mitosis/cell maturation and differentiation. Testosterone is converted to 5-DHT by 5alpha-reductase, usually with in the target tissues of 5-DHT because of the need for high concentrations of ...

    One year before, still as an undergraduate, he analysed epidermal skin cells as part of an open competition organised by Berlin University. The branched skin cells resembling neuron, described in his paper entitled “On the nerves of the human skin,” remained an enigma for over a century before their immunological function and significance ...

  9. Endocrine gland - Wikipedia

    en.wikipedia.org/wiki/Endocrine_gland

    The alpha and beta cells are the endocrine cells in the pancreatic islets that release insulin and glucagon and smaller amounts of other hormones into the blood. Insulin and glucagon influence blood sugar levels. Glucagon is released when the blood glucose level is low and stimulates the liver to release glucose into the blood. Insulin ...
