TYPES OF SQUAMOUS EPITHELIUM

Squamous Epithelium is divided into 2 types

• • Simple Squamous Epithelium
  • Stratified Squamous Epithelium

SIMPLE SQUAMOUS EPITHELIUM

• Made up of single layer of cells.
• It is also called as Pavement epithelium or Tessellated epithelium.
• Mainly present in regions where diffusion occurs.
• The cells resemble floor – tiles. The length and breadth of the cells is more than the thickness of the cells.
• Examples
  • Alveolar Epithelium
  • Inner lining of Bowman’s capsule
  • Capillary epithelium (Endothelium)
  • Coelomic epithelium (Peritonium)
  • Pleural membrane (covering of lungs)
  • Eye-lens epithelium.

STRATIFIED SQUAMOUS EPITHELIUM

• Made up of multiple layer of cells (more than 6 cells thick)
• Cells of top layer are squamous.
• Mainly present in regions where protection is required or wear and tear is common.
• Examples
  • Lining of Buccal cavity (Cheek epithelium)
  • Skin
  • Pharynx
  • Vaginal epithelium
  • Urethra
  • Conjuctiva
