GENERAL HISTOLOGY

Detailed explanation-1: -Cilia: Cilia are tiny, hair-like, motile (they can move) structures on the surface of the cell that help move entire cells or can move substances along the outer surface of the cell.

Detailed explanation-2: -As their name suggests, ciliated columnar epithelial cells are rectangular in shape and have between 200 to 300 hair-like protrusions called cilia (see Figure 1). The mitochondria are found toward the apical region of the cell while the cell nuceli are found towards the base and are often elongated.

Detailed explanation-3: -The airway epithelium cells are columnar in shape and tapers towards the lumen and each cell can have as many as 200–300 cilia on the luminal surface [2].

Detailed explanation-4: -So, the correct answer is ‘Ciliated epithelium’.

Detailed explanation-5: -Ciliated epithelium protects the interior of the bronchioles and fallopian tubes. This enables particles or mucus to travel in a wave-like fashion in a certain direction. On top of a tissue or cell are cilia, which resemble hairs.
