Understanding Epithelial Tissue

Which of the following best describes the main function of epithelial tissue?

• Transmitting electrical impulses

• Covering body surfaces and lining cavities

• Storing fat

• Producing blood cells

What is the primary characteristic that distinguishes epithelial tissue from other tissue types?

• Presence of a matrix with fibers

• Closely packed cells with minimal extracellular material

• Ability to contract

• Presence of neurons

Which type of epithelial tissue is specialized for diffusion and filtration?

• Simple squamous epithelium

• Transitional epithelium

• Pseudostratified columnar epithelium

Where would you most likely find stratified squamous epithelium in the human body?
