What does JM mean in BRITISH MEDICINE
JM is an abbreviation that stands for juxtamedullary. This medical term refers to nephrons, the primary filtering units in the kidneys. Juxtamedullary nephrons are located close to the renal medulla and perform a special role in urine production. In this article, we will look at the meaning of JM and its significance within medical science.
JM meaning in British Medicine in Medical
JM mostly used in an acronym British Medicine in Category Medical that means juxtamedullary
Shorthand: JM,
Full Form: juxtamedullary

The Significance of Juxtamedullary Nephrons
Juxtamedullary nephrons are crucial components of healthy urinary production as they allow excess nitrogen-based waste products such as urea to be removed from the body via urine formation. They can be stimulated to secrete more substances than what is normally excreted by creating a hypertonic environment with increased osmotic pressure, enabling them to filter out these abnormal amounts of material from circulation even under normal physiological conditions. Moreover, juxtamedullary nephrons play an important role in maintaining sodium balance by regulating its reabsorption back into circulation through tubules located near proximal convoluted tubules (PCTs). As such, they help regulate overall homeostasis and keep blood levels of electrolytes within safe ranges at all times.
Essential Questions and Answers on juxtamedullary in "MEDICAL»BRITMEDICAL"
What is Juxtamedullary Nephron?
Juxtamedullary nephrons are the longest and most complex type of nephrons in the human kidney. They are located deep within the cortex near the junction between the cortex and medulla, which is why they are called juxtamedullary nephrons. The key feature of juxtamedullary nephrons is their long loops of Henle that extend into the inner medulla, allowing them to reabsorb more water than other types of nephrons.
What does Juxtamedullary mean?
Juxtamedullary is a term used to describe something that's located near or adjacent to the medulla, such as certain types of nephrons found in the human kidney. It comes from two Latin words; "juxta", meaning "beside" and "medulla", meaning "marrow".
How many Juxtamedullary Nephrons are there?
There are approximately 500-1,000 juxtamedullary nephron in each normal sized human kidney. These nephron make up about 10-20% of all renal functional units or glomeruli found in the kidney.
What role do Juxtamedullary Nephrons play in urine formation?
Juxtamedullary nephrons play an important role in urine concentration by helping increase its osmolarity, or solute concentration, when needed. By extending their loops of Henle deep into the medulla, they can reabsorb more water than other types of nephron and help create a more concentrated urine.
Are Juxtamedullary Nephron unique compared to other Types?
Yes, unlike other types of renal functional units or glomeruli, juxtameudllay nephrons have long loops of Henle that extend deep into the medulla so that they can reabsorb more water when needed. This allows them to concentrate urine for more efficient excretion and contribute significantly to overall renal function.
How do Juxtameudllay Nephron Differ From Cortical Nephron?
Cortical nephrons differ from juxtameudllay nephron because they don't have long loops of Henle like juxtameudllay do; instead their glomerulus lie close to Bowman's capsule within cortex only and their main function is filtration rather than concentrating urine as seen with juxtapemdulalry ones
Final Words:
In conclusion, JM stands for juxtamedullary – a type of nephron found close to the renal medulla that helps regulate urinary production by removing metabolic waste products such as urea from circulation. These specialized cells also play an important role in controlling electrolyte balance through their regulation of sodium absorption across PCTs within each kidney. Thus, JM is critical for both kidney health and proper bodily homeostasis overall.
