Epithelial Tissue Anatomy Questions and Answers
- 1.
What type of tissue is characterized by a single layer of flat, scale-like cells with oval or spherical nuclei, optimized for functions such as diffusion, osmosis, and filtration?
- A.
Simple squamous
- B.
Simple cuboidal
- C.
Simple columnar
- D.
Simple stratified
Correct Answer
A. Simple squamousExplanation
The tissue described in the question is simple squamous. This tissue is characterized by a single layer of flat, scale-like cells with oval/spherical (squished) nuclei. It is thin in structure, which allows for efficient diffusion, osmosis, and filtration. Simple squamous tissue is found in areas where these processes are important, such as the lining of blood vessels, air sacs in the lungs, and the kidneys.Rate this question:

What type of tissue, characterized by a single layer of rectangular cells with oval nuclei typically located close to the basal surface, lacking cilia but often containing goblet cells, primarily functions in secretion and absorption?
- A.
Simple squamous
- B.
Simple cuboidal
- C.
Simple columnar ciliated
- D.
Simple columnar non-ciliated
Correct Answer
D. Simple columnar non-ciliatedExplanation
The given description of the tissue indicates that it is a single layer of rectangular cells with oval nuclei close to the basal surface, no cilia, and usually contains goblet cells. This matches the characteristics of simple columnar non-ciliated epithelial tissue. This type of tissue is involved in secretion and absorption.Rate this question:

What type of tissue, characterized by a single layer of rectangular cells with oval nuclei usually situated close to the basal surface, possessing cilia on the apical surface, primarily functions in secretion while the cilia aid in moving materials along the cell's surface?
- A.
Simple squamous
- B.
Simple cuboidal
- C.
Simple columnar ciliated
- D.
Simple columnar non-ciliated
Correct Answer
C. Simple columnar ciliatedExplanation
The tissue described in the question has a single layer of rectangular cells with oval nuclei close to the basal surface. It also has cilia, which are hair-like structures on the apical surface. These characteristics match with the description of simple columnar ciliated epithelium. This type of tissue is involved in secretion and the movement of material along the surface of the cell.Rate this question:

- 4.
What type of tissue featuring a single layer of cells that gives the appearance of being stratified, with oval-shaped nuclei located at varying depths and possessing cilia, primarily functions in secretion and facilitates the movement of materials across the surface of the cells?
- A.
Simple columnar
- B.
Pseudostratified columnar
- C.
Stratified columnar
Correct Answer
B. Pseudostratified columnarExplanation
The correct answer is pseudostratified columnar. This type of epithelial tissue appears stratified due to the varying depths of its oval-shaped nuclei. It also has cilia and is involved in the secretion and movement of materials across the surface of cells. Simple columnar and stratified columnar do not have these characteristics, making pseudostratified columnar the correct answer.Rate this question:

- 5.
What type of tissue, characterized by multiple layers of cells where apical surface cells are flattened and basal cells are cuboidal to columnar, with apical cells containing keratin and lacking a nucleus, primarily functions in providing protection?
- A.
Stratified squamous non-keratinized
- B.
Stratified squamous keratinized
- C.
Pseudostratified columnar
- D.
Transitional
Correct Answer
B. Stratified squamous keratinizedExplanation
The tissue described in the question has multiple layers of cells, with flattened cells on the apical surface and cuboidal to columnar cells at the basal surface. The apical cells contain keratin and do not have a nucleus. This tissue is involved in protection. Based on these characteristics, the correct answer is stratified squamous keratinized.Rate this question:

- 6.
What is the primary function of epithelial tissue?
- A.
Protection
- B.
Contraction
- C.
Secretion
- D.
Transmission
Correct Answer
A. ProtectionExplanation
Epithelial tissue serves as the body's frontline defense, primarily functioning in protection against external factors. It forms tight barriers that shield underlying tissues and organs from physical abrasion, chemical damage, and invasion by pathogens. Epithelial layers line various body surfaces, including the skin, digestive tract, respiratory passages, and reproductive organs.Rate this question:

Which of the following is NOT a type of epithelial tissue?
- A.
Squamous
- B.
Cuboidal
- C.
Columnar
- D.
Connective
Correct Answer
D. ConnectiveExplanation
Epithelial tissue constitutes one of the four primary types of animal tissues, distinct from connective, muscle, and nervous tissues. While connective tissue provides structural support, binds organs together, and cushions against mechanical stress, epithelial tissue specializes in covering surfaces, lining cavities, and forming glands. Epithelial cells exhibit polarity, with distinct apical and basal surfaces, and form tightly packed sheets held together by junctional complexes.Rate this question:

Where can simple squamous epithelium be found?
- A.
Alveoli
- B.
Skin
- C.
Stomach
- D.
Bone marrow
Correct Answer
A. AlveoliExplanation
Simple squamous epithelium can be found in structures where rapid diffusion or filtration occurs. Examples include the alveoli of the lungs, where it facilitates gas exchange, and the lining of blood vessels (endothelium) and lymphatic vessels (mesothelium), where it permits the exchange of nutrients and waste products.Rate this question:

What is the shape of cells in simple cuboidal epithelium?
- A.
Squamous
- B.
Cube-shaped
- C.
Columnar
- D.
Irregular
Correct Answer
B. Cube-shapedExplanation
Simple cuboidal epithelium is characterized by cube-shaped cells. This type of epithelium is commonly found in glandular tissues and in parts of the kidney tubules, where it functions in secretion and absorption. The shape of the cells allows for efficient absorption and secretion of substances.Rate this question:

Which epithelial tissue lines the urinary bladder?
- A.
Stratified
- B.
Simple
- C.
Transitional
- D.
Pseudostratified
Correct Answer
C. TransitionalExplanation
Transitional epithelium lines organs such as the urinary bladder, ureters, and parts of the urethra. It is characterized by its ability to stretch and accommodate fluctuations in volume, such as the expansion of the bladder as it fills with urine. Transitional epithelium is stratified (consisting of multiple layers of cells) and undergoes changes in cell shape depending on the degree of distension of the organ.Rate this question:
