What are the differences between the renal cortex and the renal medulla?
It is divided into smaller sections called as renal pyramids. The difference between renal cortex and renal medulla is, the renal cortex is the outer portion of the kidney whereas renal medulla is the innermost part of the kidney.
How can you distinguish between the renal cortex and the renal medulla under the microscope?
The renal medulla, the region internal to the cortex that contains parallel tubules (nephron loops, collecting tubules and collecting ducts) and blood vessels, their shape on your slide depending on how they’re sectioned. The absence of renal corpuscles distinguishes the medulla.
Why is the renal medulla darker than the renal cortex?
Cortex and medulla The renal cortex is the outer layer of the kidney tissue. It is darker than its underlying renal medulla because it receives over 90\% of the kidney blood supply. The cortex has a grainy appearance, as it mostly contains ovoid and coiled parts of the nephrons (renal corpuscles and convoluted tubules).
Is cortex and renal cortex the same?
The renal cortex is the outer portion of the kidney between the renal capsule and the renal medulla. In the adult, it forms a continuous smooth outer zone with a number of projections (cortical columns) that extend down between the pyramids….

How can you rapidly distinguish the renal cortex from the renal medulla on a slide?
How can one easily discern the renal cortex from the renal medulla on a microscope slide? Glomeruli are only present in the renal cortex.
What is the function of the medulla in the kidney?
The main function of the medulla is to regulate concentration of the urine. The urine flows from the collecting ducts into the renal calyces and pelvis, which undergoes unidirectional peristaltic movements to allow drainage of the urine into the downstream ureter and bladder.
What is the difference between renal pelvis and renal papilla?
Note: The ureter collects the urine from the kidney to the urinary bladder….Complete answer:
| Renal Pelvis | Renal papilla |
|---|---|
| Renal pelvis is the portion formed by the union of two or three calyces. | It is the location where the renal pyramids present in the medulla empty urine into the minor calyx. |
What is in renal medulla?
The mature renal medulla, the inner part of the kidney, consists of the medullary collecting ducts, loops of Henle, vasa recta and the interstitium. The unique spatial arrangement of these components is essential for the regulation of urine concentration and other specialized kidney functions.
What is the cortex and medulla of the kidney?
The main difference between renal cortex and renal medulla is that renal cortex is the outer region of the kidney which contains blood vessels connected to the nephrons whereas renal medulla is the inner region of the kidney which contains 8-12 renal pyramids.
Is the renal columns part of the medulla or cortex?
The renal column (or Bertin column, or column of Bertin) is a medullary extension of the renal cortex in between the renal pyramids. It allows the cortex to be better anchored. Each column consists of lines of blood vessels and urinary tubes and a fibrous material.
What is located in the renal medulla How do these structures affect coloration of the medulla?
Nephrons are the functional unit of the kidneys. What is located in the renal medulla, and how do these structures affect coloration of the medulla? The tissue within the medulla is a dark red color due to the amount of blood dispersed into it via the renal artery which is further divided into interlobar arteries.
What is cortex in kidney?
The renal cortex is the outer part of the kidney. It contains the glomerulus and convoluted tubules. The renal cortex is surrounded on its outer edges by the renal capsule, a layer of fatty tissue. Together, the renal cortex and capsule house and protect the inner structures of the kidney.
What does separate the renal cortex from the medulla?
The conical renal pyramids are composed of medullary tissue with their bases abutting the cortex and their apices forming a papillae. Renal columns are cortical tissue that is interposed between the pyramids. Arcuate blood vessels separate the cortex from the medulla.
What is the difference between the medulla and the renal pyramid?
Renal pyramids. The base of each pyramid faces the outer portion of the kidney, which is called the renal cortex. The renal cortex is located between the renal medulla and the renal capsule. The renal capsule is defined as the layer that surrounds the kidneys with tough fibrous tissue. The capsule is covered in a connective fatty tissue.
What is the normal renal cortex measurement?
The normal adult kidney measures approximately 13 cm in length and 4-6 cm in width. The thickness of the renal cortex can be 12 mm. The renal pelvis measures about 4 cm in length.
Is renal insufficiency and kidney failure the same thing?
Renal insufficiency in simpler terms refers to kidney failure. In other words, renal insufficiency, and kidney failure all mean the same thing. Another name for renal insufficiency is kidney insufficiency when the kidneys are not able to perform normal day-to-day functions.
