Calyx (botany), the collective name for the sepals of a flower; Calyce, a genus of beetles; Calyx, a genus of sea sponges; Calyx of Held, a large synapse in the auditory brainstem structure; Eubela calyx, species of sea snail; Renal calyx, a chamber in the kidney that surrounds the apex of the renal pyramids
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 ...
Calyx is a term used in animal anatomy for some cuplike areas or structures. Etymology. Latin, from calyx (from Ancient Greek κάλυξ, case of a bud, husk").
Having petal s and stamen s attached to the calyx. calycophyll Leaf-like structure formed from a sepal or calyx lobe which enlarges, usually many-fold, before or after anthesis, especially when most of the other sepals or calyx lobes retain their original size. More extreme than an accrescent calyx, calycophylls are found in Rubiaceae.
The large calyx of the medlar fruit is the source of its vulgar nicknames. The term sepalum was coined by Noël Martin Joseph de Necker in 1790, and derived from Ancient Greek σκέπη (sképē) 'covering'. [5] [6] Collectively, the sepals are called the calyx (plural: calyces), [7] the outermost whorl of parts that form a flower
The renal pelvis or pelvis of the kidney is the funnel-like dilated part of the ureter in the kidney.It is formed by the convergence of the major calyces, acting as a funnel for urine flowing from the major calyces to the ureter.
The renal filtrate it carries drains into a minor calyx as urine. [6] The cells that comprise the duct itself are similar to rest of the collecting system. The duct is lined by a layer of simple columnar epithelium resting on a thin basement membrane. The epithelium is composed primarily of principal cells and α-intercalated cells. [7]
A glycocalyx, literally meaning "sugar coat" (glykys = sweet, kalyx = husk), is a network of polysaccharides that project from cellular surfaces of bacteria, which classifies it as a universal surface component of a bacterial cell, found just outside the bacterial cell wall.
