Renal pyramid vs renal medulla

the majority of the renal tubule reside in the renal cortex, whereas varying amounts of the renal tubule dip into the renal medulla. The tip of each renal pyramid tapers into a slender papilla (pah-PIL-ah; papil-= "nipple"), which borders on the first urine-draining structure, a cup-shaped tube called a minor calyx (KAY-Cortex and Medulla. A longitudinal or transverse section through the kidney reveals the parenchyma, which is divided into the outer, dark red cortex and the inner, lighter-colored medulla (Figs. 11-1 and 11-2).The structures within the renal cortex are arranged in medullary rays and the cortical labyrinth (Figs. 11-2 and 11-3).These terms arose because, unlike the medulla, which is composed ...dorsal and ventral kidney diverticulum and the interlobular vessels originate from the bassinet and radially pass along the cortex. In the whole lateral renal scan, the medulla is seen as a distinct area throughout the entire kidney. Renal ridge is seen easily in the mid-sectional view along with the kidney diverticulum.Usually involves tips & central portions of pyramids Bases of pyramids typically remain hypoechoic Diffuse involvement of entire medullary pyramid uncommon May appear as layering gradient of ↑ echogenicity, brightest at tips of pyramids Posterior acoustic shadowing typically absent Bilateral > unilateral renal involvementRare developmental anomaly Leads to rapid renal failure, commonly perinatal or neonatal Congenital hepatic fibrosis in infantile and juvenile forms Enlarged kidneys with smooth external appearance Sponge-like cortex and medulla Saccular to cylindrical dilatation of collecting tubule origin (cuboidal epithelium)Filtration. Filtration is the mass movement of water and solutes from plasma to the renal tubule that occurs in the renal corpuscle. About 20% of the plasma volume passing through the glomerulus at any given time is filtered. This means that about 180 liters of fluid are filtered by the kidneys every day. Thus, the entire plasma volume (about 3 ... The human kidney contains between 8 and 18 medullary pyramids separated by the renal columns of the cortex. To account for the large surface of contact between the medullary pyramids and the renal cortex, as well as the papillae and the renal pelvis, 5 half-ellipsoids are used in the present model for each kidney.On gross kidney identify: cortex, medulla, papillae at apex of medullary minor calyces, major calyces, renal pelvis 4.
