====Renal Medulla====

The renal medulla contains medullary pyramids. The part nearest the cortex is the base of the pyramid which narrows to form the inner part; the renal papilla. The medulla can be split into two parts, the outer and the inner. Different parts of the [[:Category:Nephron| nephron]] reside in these areas

The renal medulla is the inner layer of renal parenchyma.  It contains '''renal pyramids'''. The part nearest the cortex is the base of the pyramid which narrows to form the inner part; the '''renal papilla'''. The renal papilla is the apex of the lobule where urine enters the ureters. In the horse, medullary pyramids are completely fused to form a '''renal crest'''.  The medulla can be split into two parts, the outer and the inner. Different parts of the [[:Category:Nephron| nephron]] reside in these areas.
