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
