Ciliated Epithelium MCQ - Practice Questions with Answers

Simple Ciliated Epithelium:
Structure 

• The cells of ciliated epithelium bear numerous hair-like outgrowths called cilia. These arise from basal granules.
• In ciliated epithelium, mucus containing goblet cells are also found. 
• The cilia undergo rhythmic contractions and create a current to transport material. 

Ciliated epithelium is of two types :
(a). Ciliated columnar epithelium- This epithelium consists of cilia containing column-like cells. 
(b). Ciliated cuboidal epithelium- It consists of cube-like cells having cilia on their free surfaces.

Location:

• Ciliated columnar epithelium lines respiratory tract, fallopian tubes, ventricles of the brain, central canal of the spinal cord, tympanic cavity of the middle ear and auditory tube (Eustachian tube). 
• Ciliated cuboidal epithelium occurs in certain parts of nephrons of the kidney. 

Functions: 

• The major function of the cilia of epithelium is to cause ciliary movements. These movements maintain a flow of mucus or liquid constantly in one direction. 
• In oviduct, cilia help to move an egg towards the uterus
• In the respiratory tract, cilia help to push mucus towards the pharynx 
• In the nephrons, cilia keep the urine moving
• Cilia of ventricles of the brain and central canal of the spinal cord helps to maintain the circulation of cerebrospinal fluid. 
• Stratified ciliated columnar epithelium
• The outer layer consists of ciliated columnar cells while the basal layer possesses columnar cells.
• It covers larynx and upper part of the soft palate.
