Either a minor calyx in the kidney, a conglomeration of two or three minor calyces to form a major calyx, or the Calyx of Held, a particularly large synapse in the mammalian auditory central nervous system, named by H. Held in his 1893 article Die centrale Gehörleitung, [3] due to its flower-petal-like shape.
The renal calyces (sg. calyx) are conduits in the kidney through which urine passes. The minor calyces form a cup-shaped drain around the apex of the renal pyramids.Urine formed in the kidney passes through a renal papilla at the apex into the minor calyx; four or five minor calyces converge to form a major calyx through which urine passes into the renal pelvis (which in turn drains urine out ...
Organ trade (also known as the blood market or the red market) is the trading of human organs, tissues, or other body products, usually for transplantation. [1] [2] According to the World Health Organization (WHO), organ trade is a commercial transplantation where there is a profit, or transplantations that occur outside of national medical systems.
Discodermia dissoluta is a species of deep-water sea sponge found in the Eastern, Southern, and Southwestern Caribbean, as well as in the Greater Antilles. This sponge is of particular interest to bio and organic chemists due to its production of a potent chemical compound called (+)-discodermolide, which has potential therapeutic applications for cancer treatment.
The human brain is about 60% fat by weight, far more than any other organ. Essential fatty acids, such as omega 3s, are key to the strength and performance of the brain’s cells. Since the human ...
The glycocalyx is located on the apical surface of vascular endothelial cells which line the lumen.When vessels are stained with cationic dyes such as Alcian blue stain, transmission electron microscopy shows a small, irregularly shaped layer extending approximately 50–100 nm into the lumen of a blood vessel.
Calyx of Held microstructure. The calyx of Held is a particularly large excitatory synapse in the mammalian auditory nervous system, so named after Hans Held who first described it in his 1893 article Die centrale Gehörleitung [1] [2] because of its resemblance to the calyx of a flower. [3]
The third portion of the nervous system lies aborally, and is responsible for the flexing and movement actions of the arms, pinnules and cirri. This is centred on a mass of neural tissue near the base of the calyx, and provides a single nerve to each arm and a number of nerves to the stalk. [5]
