The etymology of the Nephr Medical Term
The Nephr medical term is derived from the Greek word “Nephros” which means kidney. The Nephr prefix is used in relation to medical terms that describe structures or pathologies related to the kidney.
The nephr root word cannot only be used as a prefix, but also as an inter-fix. This means that it can be combined with two other morphemes; another prefix and a suffix to still describe something that is happening with or related to the kidney.
Nephr Definition: Information About the Kidney
The kidneys are two retroperitoneal structures that are ordinarily situated between the transverse processes of T12-L3 vertebrae, with the left kidney slightly above the right in position. The upper poles are typically placed more medially and posteriorly than the lower poles.
The kidneys serve significant functions, including filtration and discharge of metabolic byproducts (urea and ammonium); regulation of essential electrolytes, liquid, and acid-base equilibrium; and stimulation of red blood cell formation. They additionally contribute to the management of blood pressure through the renin-angiotensin-aldosterone system, controlling reabsorption of water and keeping up with the intravascular volume.
The kidneys are bean-shaped and weigh around 150 g in the male and around 135 g in the female. They are normally 10-12 cm long, 5-7 cm in width, and 2-3 cm in thickness.
The relationship of adjoining structures to the kidneys is significant, as depicted below:
- Superiorly, the suprarenal (adrenal) glands sit adjoining the upper pole of the both kidneys
- On the right side, the second part of the duodenum (descending part) abuts the medial part of the kidney
- On the left side, the greater cuvature of the stomach can wrap over the superomedial part of the kidney, and the tail of the pancreas might reach out to overlie the renal hilum
- The spleen is found foremost to the upper pole and is associated by the splenorenal (lienorenal) tendons
- Inferiorly to these organs, the colon normally rests anteriorly to the kidneys on the two sides
- Posteriorly, the stomach covers the upper third of every kidney, with the twelfth rib most normally crossing the upper pole
- The kidneys sit over the psoas (medially) and the quadratus lumborum muscles (laterally)
