Study Notes
Kidney Location and Structure
- Kidneys are located in the retroperitoneal region, posterior to the abdominal wall, and adjacent to the vertebral column.
- The right kidney is positioned higher than the left kidney.
Hilum and Renal Sinus
- Each kidney has a hilum, which extends into the renal sinus.
- The hilum transmits the renal vein, branches of the renal arteries, pelvis, and ureter.
Kidney Covering
- The kidneys are covered by four layers: fibrous capsule, peri-renal fat, renal fascia, and para-renal fat.
Kidney Internal Structure
- The kidney consists of two main regions: the cortex (dark brown) and the medulla (light brown).
- The medulla is composed of renal pyramids, each with a base and an apex, known as the renal papilla.
Renal Pelvis and Calyces
- The renal pelvis is the upper expanded end of the ureter within the sinus.
- The renal pelvis divides into three major calyces, each of which further divides into three minor calyces.
- Each minor calyx is indented by the apex of a renal pyramid, also known as the renal papilla.
This quiz covers the structure and location of the kidneys, including their position in the abdominal wall, hilum, and covering layers. It also explores the internal composition of the kidneys, including the cortex and medulla.
