What is the medial border of the kidneys called?
The renal hilum (Latin: hilum renale) or renal pedicle is the hilum of the kidney, that is, its recessed central fissure where its vessels, nerves and ureter pass. The medial border of the kidney is concave in the center and convex toward either extremity; it is directed forward and a little downward.
What is the mid pole of the kidney?
The kidney is bean-shaped with a superior and an inferior pole, anterior and posterior surfaces, and lateral and medial borders. The midportion of the kidney is often called the midpole. The kidney has a fibrous capsule, which is surrounded by perirenal fat.
What is the inner part of the kidney called?
A frontal section through the kidney reveals an outer region called the renal cortex and an inner region called the renal medulla (Figure 25.1.
What are the 3 sections of the kidney called?
The kidney is made up of three different regions internally: the outer cortex, the middle medulla (with the renal pyramids) and the inner-most renal pelvis.
What is the renal papilla?
Definition of renal papilla anatomy. : the apex of a renal pyramid which projects into the cavity of a calyx (see calyx sense 2) of the kidney and through which collecting ducts discharge urine.
The medial border of the kidney contains a very important landmark called the hilum of the kidney, which is the entry and exit point for the kidney vessels and ureter.
What is the innermost layer of kidney tissue called?
The renal cortex produces erythropotein. The kidneys are made up by three external layers, which include the renal fascia (the outermost layer), the perirenal fat capsule, and lastly, the innermost layer, the renal capsule, which then surround the space of the renal cortex.
What is the internal structure of the kidney?
Internally, the kidney has three regions—an outer cortex, a medulla in the middle, and the renal pelvis in the region called the hilum of the kidney. The hilum is the concave part of the bean-shape where blood vessels and nerves enter and exit the kidney; it is also the point of exit for the ureters.
What is structure of kidney?
Inside the kidneys are a number of pyramid-shaped lobes. Each consists of an outer renal cortex and an inner renal medulla. Nephrons flow between these sections. These are the urine-producing structures of the kidneys.
What is papilla of medulla?
Papilla. The renal papilla is the location where the renal pyramids in the medulla empty urine into the minor calyx in the kidney. Histologically it is marked by medullary collecting ducts converging to form a papillary duct to channel the fluid.
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 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 are two organs that are medial to the kidneys?
Left kidney anterior surface The inferior portion of the superior pole contacts with the peritoneum of the stomach (medially) and spleen (laterally)
Where does the renal artery enter the kidney?
Due to the anatomical position of the abdominal aorta (slightly to the left of the midline), the right renal artery is longer, and crosses the vena cava posteriorly. The renal artery enters the kidney via the renal hilum.
Fig 2 – The external coverings of the kidney. Internally, the kidneys have an intricate and unique structure. The renal parenchyma can be divided into two main areas – the outer cortex and inner medulla. The cortex extends into the medulla, dividing it into triangular shapes – these are known as renal pyramids.
Which is the most superior vessel in the kidney?
The most superior vessel is the renal vein which exits the kidney, just under it is the renal artery that enters in, and under the artery is the exiting ureter. Alternatively, the anterior to posterior orientation follows the same pattern: renal vein, renal artery and ureter.
Which is the anterior surface of the left kidney?
The anterior surface of the left kidney, has the following anatomical relations: Just like the right kidney, the highest part of the superior pole of the left is also covered with the left suprarenal gland F The inferior portion of the superior pole contacts with the peritoneum of the stomach (medially) and spleen (laterally)
