Bowman's capsule epithelium is which type?

Bowman's capsule epithelium is which type?

• A. Simple squamous epithelium
• B. Simple cuboidal epithelium
• C. Pseudostratified columnar epithelium
• D. Transitional epithelium

Answer: (A)

Bowman's capsule parietal layer is lined by simple squamous epithelium. This outer boundary is a single, flat cell layer that creates a thin, low-friction surface, which helps minimize the distance filtrate must travel as it enters the nephron. The visceral layer, by contrast, is made up of specialized podocyte cells wrapped around glomerular capillaries and is not a typical simple squamous lining. Other epithelial types listed—simple cuboidal, pseudostratified columnar, and transitional—are thicker and found in different parts of the urinary system, not lining Bowman's capsule.
