Renal Medulla Structure Of Human Kidney. Medullary pyramids formed by the collecting ducts inner part of the kidney. A pale outer region called renal cortex and a dark inner portion called renal medulla.
If a longitudinal section of the kidney is made by cutting with a long knife from the outer convex surface to the hilum three layers are seen. The vital structural components of a kidney are enclosed in a smooth but tough fibrous capsule called renal capsule. The renal medulla is the innermost part of the kidney the renal medulla is split up into a number of sections known as the renal pyramids blood enters into the kidney via the renal artery which then splits up to form the interlobar arteries the interlobar arteries each in turn branch into arcuate arteries which in turn branch to form interlobular arteries and these finally reach the glomeruli.
The vital structural components of a kidney are enclosed in a smooth but tough fibrous capsule called renal capsule.
Inside this capsule two distinct regions can be observed. Medulla inner region of the kidney contains 8 12 renal pyramids. The renal medulla is the innermost part of the kidney the renal medulla is split up into a number of sections known as the renal pyramids blood enters into the kidney via the renal artery which then splits up to form the interlobar arteries the interlobar arteries each in turn branch into arcuate arteries which in turn branch to form interlobular arteries and these finally reach the glomeruli. The renal medulla comprises a set of 8 18 conical structures called renal pyramids that are surrounded by the cortex.
