Pseudostratified Epithelium -

Structure:

  • The cells are columnar and unequal in size. Cells can be longer or shorter.
  • The long cells extend up to free surface while the short cells do not reach the outer free surface. 
  • Long cells have oval nuclei while short cells have rounded nuclei. 
  • Goblet cells are also present in this epithelium. 
  • The pseudostratified epithelium is so named because despite being one cell thick, it appears to be multi-layered due to the alignment of nuclei at different levels. 

It can be of two types: 
(a). Pseudostratified columnar epithelium- It is made up of columnar cells. 
(b). Pseudostratified columnar ciliated epithelium- It is made up of columnar cells in which the longer ones possess cilia while the shorter ones do not. 

Cells of pseudostratified epithelium can possess both round or oval nuclei.Option 4 is correct.
