Question

In the given diagram, which type of epithelium is indicated by the blue arrow, and what type of epithelium is represented by the surrounding tissue described as Pseudostratified Columnar Epithelium?

A) Blue arrow indicates Simple Cuboidal Epithelium; surrounding tissue is Pseudostratified Columnar Epithelium
B) Blue arrow indicates Pseudostratified Columnar Epithelium; surrounding tissue is Simple Cuboidal Epithelium
C) Blue arrow indicates Simple Columnar Epithelium; surrounding tissue is Pseudostratified Columnar Epithelium
D) Blue arrow indicates Pseudostratified Columnar Epithelium; surrounding tissue is Simple Columnar Epithelium

Answer 1

The type of epithelium indicated by the blue arrow is Pseudostratified Columnar Epithelium. The surrounding tissue is also described as Pseudostratified Columnar Epithelium. Pseudostratified columnar epithelium is found in the respiratory tract.

Step-by-step explanation:

The type of epithelium indicated by the blue arrow is Pseudostratified Columnar Epithelium. The surrounding tissue is also described as Pseudostratified Columnar Epithelium. Pseudostratified columnar epithelium is a type of epithelium that appears to be stratified but actually consists of a single layer of irregularly shaped and differently sized columnar cells. It is found in the respiratory tract, where some of these cells have cilia.
