In Malaysia, the reason for its other common local name, translated to "The Sultan Fish" is attributed to the claim that the fish was a favorite among royal members and that palace workers would go to markets and call for any fishermen that had the Sultan's fish.
A hormone (from the Greek participle ὁρμῶν, "setting in motion") is a class of signaling molecules in multicellular organisms that are sent to distant organs or tissues by complex biological processes to regulate physiology and behavior. [1] Hormones are required for the correct development of animals, plants and fungi. Due to the broad ...
A total of 36 genes are significantly enriched in ε-cells that aid in proteinase inhibition, processing of hormones, cell migration, and immune activity that differentiates them from α-, β-, δ- and PP-cells. [7] Additionally, the secretory vesicles of ε-cells (110±3 nm) are much smaller than those of α-cells (185±7 nm). [5]
The function of beta cells is primarily centered around the synthesis and secretion of hormones, particularly insulin and amylin.Both hormones work to keep blood glucose levels within a narrow, healthy range by different mechanisms. [4]
Alpha cells are endocrine cells, meaning they secrete a hormone, in this case glucagon. Alpha cells store this glucagon in secretory vesicles that typically have an electron dense core and a grayish outer edge. [1] It is believed that alpha cells make up approximately 20% of endocrine cells within the pancreas. [1]
A gonad, sex gland, or reproductive gland [1] is a mixed gland and sex organ that produces the gametes and sex hormones of an organism. Female reproductive cells are egg cells, and male reproductive cells are sperm. [2] The male gonad, the testicle, produces sperm in the form of spermatozoa. The female gonad, the ovary, produces egg cells.
Leydig cells release a class of hormones called androgens (19-carbon steroids). [8] They secrete testosterone, androstenedione and dehydroepiandrosterone (DHEA), when stimulated by the luteinizing hormone (LH), which is released from the anterior pituitary in response to gonadotropin releasing hormone which in turn is released by the hypothalamus.
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.
