Comparison between Simple Columnar Epithelium and Stratified Columnar Epithelium MCQ - Practice Questions with Answers

Simple Columnar Epithelium 
Structure

• The columnar epithelium consists of elongated cells which are placed side by side like columns with slightly roader outer free surfaces.
• The nuclei of these cells are elongated and lie near the bases of the cells.  
• Some cells of this epithelium contain mucus and look like goblets. These are called goblet cells. 
• The epithelium containing goblet cells i.e. mucus-secreting cells along with the underlying connective tissue is called mucosa. These are found in the stomach and intestine. 
• Location
• Simple columnar epithelium lines the stomach, intestine, gallbladder and bile ducts.
• The columnar epithelium also forms gastric glands, intestinal glands etc. 

Function: The function of columnar epithelium is protection, secretion and absorption.

Stratified Columnar Epithelium:

• It possesses columnar cells in both superficial and basal layers. 
• It lines epiglottis and mammary gland ducts and parts of urethra.
