Question 1

Which type of epithelial tissue is shown in the first image, and what is its primary function in the respiratory tract?

Accepted Answer

Pseudostratified ciliated columnar epithelium; trapping and moving particles out of the airway

Question 2

Which cell type in the respiratory epithelium is responsible for mucus production, and what is its function?

Accepted Answer

Goblet cell; traps dust and microbes

Question 3

What is the main structural difference between simple and pseudostratified columnar epithelium?

Accepted Answer

Simple columnar has one layer, pseudostratified appears multilayered but all cells touch the basement membrane

Question 4

Which structure separates the epithelial tissue from the underlying connective tissue?

Accepted Answer

Basement membrane

Question 5

In the second image, which layer contains the majority of blood vessels, nerves, and glands?

Accepted Answer

Dermis

Question 6

Which connective tissue type is most abundant in the dermis and provides strength and elasticity?

Accepted Answer

Dense irregular connective tissue

Question 7

A patient suffers a burn that destroys the epidermis and dermis but not the underlying muscle or bone. What degree of burn is this, and what is the primary clinical concern?

Accepted Answer

Third-degree; dehydration

Question 8

Which of the following best describes the function of cilia in the respiratory epithelium?

Accepted Answer

Move mucus and trapped particles toward the pharynx

Question 9

Which layer of the skin is responsible for mitosis and regeneration of new skin cells?

Accepted Answer

Stratum basale (germinativum)

Question 10

Which of the following is a correct pairing of tissue type and its primary function?

Accepted Answer

Stratified squamous epithelium; protection against abrasion

Question 11

Which of the following best describes the role of the basement membrane in epithelial tissues?

Accepted Answer

It anchors epithelial tissue to underlying connective tissue

Question 12

Which of the following is NOT a characteristic of epithelial tissue?

Accepted Answer

Cells are widely spaced with abundant matrix

Question 13

Which type of gland secretes its product directly into the bloodstream without using ducts?

Accepted Answer

Endocrine gland

Question 14

Which connective tissue cell type is responsible for producing fibers such as collagen and elastin?

Accepted Answer

Fibroblast

Question 15

A tissue sample shows multiple layers of flat cells at the surface and is found lining the mouth. What is the most likely tissue type?

Accepted Answer

Stratified squamous epithelium

Question 16

Which of the following best describes the function of the lamina propria?

Accepted Answer

It is a loose connective tissue that supports the epithelium

Question 17

Which of the following is a correct description of the process of preparing a tissue slide for microscopy?

Accepted Answer

Fixation, sectioning, smearing, staining

Question 18

Which of the following is a function of adipose tissue?

Accepted Answer

Storage of energy and insulation

Question 19

Which of the following best describes the difference between keratinized and nonkeratinized stratified squamous epithelium?

Accepted Answer

Keratinized contains a layer of dead cells filled with keratin, nonkeratinized does not

Question 20

Which of the following is the correct order of the layers of the skin from superficial to deep?

Accepted Answer

Epidermis, dermis, hypodermis
