Renal Papilla (Anterior Part; Right) Structure/Morphology
The renal papillae are described as the apex or pointed end of each renal pyramid. Each papilla projects into a minor calix, which lies in the central space of the renal pelvis.
A distinct feature of papillae is their sieve-like appearance, which can be attributed to the presence of many small openings on their surface. Each opening represents a small tubule called the papillary duct, into which the collecting tubules within the renal pyramid converge.
