Which type of epithelium is composed of multiple layers, including an apical layer containing tall, slender cells?
Mademuasel [1]

The question is incomplete as it does not have the options which are:

  • Simple squamous
  • Simple columnar
  • Pseudostratified squamous
  • Stratified squamous
  • Stratified columnar

Answer:

Stratified columnar

Explanation:

Epithelial tissue is the tissue formed by the cells which form a layer of cell and lines the lumen of the organ and also covers the organs. The epithelial tissue can be classified based on the number of layer and shape of the cell.

In the given question, the shape of the cell is slender and are tall therefore are called columnar. The cells form more than one layer or multiple layers therefore form stratified layers.

Therefore,  the epithelial tissue formed by these slender shaped multiple layers is known as the stratified columnar layer. The stratified columnar is present in the respiratory tract and the digestive tract.

Thus,  Stratified columnar is the correct answer.
