• The height of the cells is more than the length or the breadth.
• The cells appear column like in shape.

SIMPLE COLUMNAR EPITHELIUM

• Made up of single layer of cells.
• The cells are elongated column-like.
• Epithelial lining containing Columnar epithelium is generally secretory or glandular.
• Examples
  • Lining of Gall bladder.
  • Lining of stomach and intestines.
  • Lining of Acini of Pancreas.
  • Stratum germinativum of Skin.

CILIATED COLUMNAR EPITHELIUM

• Bears cilia on the apical surface of the cell
• Cilia beats in a synchronised manner with adjacent cells
• Helps in movement of substances over the surface of epithelium

BRUSH BORDERED COLUMNAR EPITHELIUM

• Small cytoplasmic projections called Microvilli are present.
• Microvilli increases the surface area for secretion and absorption
