Document Summary
This is a guide for identifying structures; function is listed only if it helps in this regard. Kidney cortex: contains distinctive glomeruli, convoluted tubules, parts of collecting ducts. Kidney medulla: below the cortex, contains limbs of henle, collecting ducts. Medullary ray: collecting ducts that extend into cortex. Calyx: terminal expansions of ureter in the kidney, minor calyces meet up with papilla. Papilla: termination of collecting duct into a minor calyx. Lobe: a medullary pyramid and the overlying cortex. Lobule: lateral borders marked by medullary rays. Arteries in order: abdominal aorta, renal artery, interlobar, arcuate, interlobular, intralobular, afferent arteriole, glomerulus, efferent arteriole, vasa recta. Capillary endothelium: highly fenestrated for high filtration rate. Afferent arteriole: at vascular pole of renal corpuscle, distinguished from efferent arteriole if attached to an intralobular artery. Efferent arteriole: at vascular pole of renal corpuscle, see afferent arteriole. Glomerular capillary: stains pale iridescent pink in pas.
