Question type: Essay

5) Name and briefly describe the different categories of epithelial tissues based on cell shape and number of layers of cells found in the tissue.

Answer:

Difficulty: Medium

Study Objective 1: SO 4.4 Describe the properties of the different types of epithelial tissues.

Study Objective 2: SO 4.4.1 Describe the general features of epithelial tissues.

Section Reference 1: Sec 4.4 Epithelial Tissue

Solution: Based on cell shape, epithelial tissues can be divided into four categories including: 1)squamous which are thin and flat, 2)cuboidal which are similar in width and height, 3)columnar are taller than they are wide and 4)transitional which can change shape from cuboidal to squamous and back again. Epithelial tissues can also be categorized based on the number of layers of cells found in the tissue. These categories include: 1)simple which means a single layer of cells, 2)stratified which is two or more layers of cells and 3)pseudostratified which is one layer of cells that appears multi-layered due to the arrangement of the nuclei in the cells.
