Question

Brush border is a characteristic of:

• A. Secretory cells
• B. Absorptive cells
• C. Osteocytes
• D. Nerve cells

Answer 1

Answer: (B)

Absorptive cells

• Brush borders are found on the simple cuboidal and simple columnar epithelial cells having microvilli.
  
• These types of epithelium are found in the small intestine, kidney, and large intestine.
  
• This brush border structure increases the surface area and hence helps in the absorption of nutrition in the small intestine.
  

Hence, the brush border is a characteristic of absorptive cells.
