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
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.
Question type: Multiple Choice
6) Which type of epithelial tissue is found lining the heart, blood vessels and lymphatic vessels?
a) Simple squamous epithelium
b) Simple cuboidal epithelium
c) Stratified squamous epithelium
d) Stratified cuboidal epithelium
e) Simple columnar epithelium
Answer: a
Difficulty: Medium
Study Objective 1: SO 4.4 Describe the properties of the different types of epithelial tissues.
Study Objective 2: SO 4.4.2 List the location, structure, and function of each different type of
epithelial tissues.
Section Reference 1: Sec 4.4 Epithelial Tissue
7) Which type of epithelial tissue forms the most superficial layer of the skin?
a) Simple squamous epithelium
b) Simple cuboidal epithelium
c) Stratified squamous epithelium
d) Stratified cuboidal epithelium
e) Simple columnar epithelium
Answer: c
Difficulty: Medium
Study Objective 1: SO 4.4 Describe the properties of the different types of epithelial tissues.
Study Objective 2: SO 4.4.2 List the location, structure, and function of each different type of
epithelial tissues.
Section Reference 1: Sec 4.4 Epithelial Tissue
8) Which type of epithelial tissue lines the ducts of sweat glands and esophageal glands?
a) Simple squamous epithelium
b) Pseudostratified columnar epithelium
c) Stratified squamous epithelium
