10.

The type of epithelial cells which line the inner surface of Fallopian tubes, bronchioles and small bronchi are known as

  • squamous epithelium

  • columnar epithelium

  • ciliated epithelium

  • cubical epithelium


C.

ciliated epithelium

Ciliated epithelium is a region of epithelium consisting of columnar or cuboidal cells bearing hairlike appendages called cilia, that are capable of beating rapidly. Ciliated epithelium performs the functions of moving particles of fluids over the epithelial surface.

Cubical ciliated epithelium occurs in certain parts of uriniferous tubules whereas columnar ciliated epithelium occurs in fallopian tubules, nasal passages, bronchioles, small bronchi and buccopharyngeal cavity of frog. It often occurs in the vicinity of mucus secreting goblet cells. Squamous epithelium are found in !inning of alveoli in the lungs and Bowman's capsule in the kidney. Columnar epithelium are found in the lining.
