Definition

1. Noun:
   • Thin double membrane surrounding the glomerulus of a nephron: The "capsula glomeruli" is the anatomical structure that forms a cup-like sac enclosing the glomerulus, a network of capillaries, in the kidney. It is the initial site of blood filtration in the formation of urine.

Usage

• The term "capsula glomeruli" is a specialized anatomical term used primarily in medical, biological, and physiological contexts to describe a specific part of the nephron, the functional unit of the kidney.
• It is often discussed in relation to kidney function, filtration processes, and renal diseases.

Examples

• Noun:
  • The filtration barrier in the kidney consists of the capillary endothelium, the basement membrane, and the capsula glomeruli.
  • Damage to the capsula glomeruli can impair the kidney's ability to filter waste from the blood.

Advanced Usage

• "Bowman's capsule": This is the most common synonym for "capsula glomeruli" in English-language anatomy. The full term is often used interchangeably.
  • The filtrate from the blood collects in the space within Bowman's capsule.

Variants and Related Words

• Glomerular capsule: Another direct synonym for "capsula glomeruli".
• Bowman's capsule: The standard English term, named after Sir William Bowman, the 19th-century English surgeon and histologist who described it.
• Nephron: The functional unit of the kidney, of which the capsula glomeruli is a part.
• Glomerulus: The knot of capillaries surrounded by the capsula glomeruli.

Synonyms

• Bowman's capsule
• Glomerular capsule

Related Terms and Concepts

• Renal corpuscle: This term refers to the structure composed of both the glomerulus and the surrounding capsula glomeruli (Bowman's capsule).
• Filtration: The primary function occurring at the capsula glomeruli, where water and solutes pass from the blood into the capsule to form filtrate.
• Podocytes: Specialized cells lining the visceral layer of the capsula glomeruli that play a crucial role in filtration.
