Question 1

Which of the following best describes the structure of a typical covering or lining membrane in the body?

Accepted Answer

An epithelial layer sitting on a basement membrane, underlain by connective tissue

Question 2

A patient suffers a deep cut that damages both the epidermis and dermis. Which of the following best explains why a scar may form instead of complete regeneration?

Accepted Answer

Fibrosis occurs when regeneration is incomplete, leading to scar tissue formation

Question 3

Which membrane type lines body cavities that open to the exterior, such as the digestive tract?

Accepted Answer

Mucous membrane

Question 4

During the organization stage of wound healing, which process is most critical for providing a foundation for new tissue growth?

Accepted Answer

Replacement of the clot by granulation tissue

Question 5

Which of the following statements about the cutaneous membrane (skin) is correct?

Accepted Answer

It consists of keratinized stratified squamous epithelium and underlying connective tissue

Question 6

A forensic scientist is analyzing fingerprints from a crime scene. Which statement about fingerprint formation is most accurate?

Accepted Answer

Fingerprints are formed by interactions between genetics and intrauterine environment

Question 7

Which of the following best explains why excessive sun exposure increases the risk of skin cancer?

Accepted Answer

Ultraviolet radiation from the sun damages DNA in skin cells, leading to mutations

Question 8

Which layer of the epidermis is responsible for the continuous production of new skin cells?

Accepted Answer

Stratum basale

Question 9

A patient with a severe heart attack loses a significant portion of cardiac muscle tissue. Why is full functional recovery unlikely?

Accepted Answer

Cardiac muscle tissue has limited or no regenerative capacity

Question 10

Which of the following equations best represents the relationship between the thickness of the skin ($$T$$), the number of epidermal layers ($$n$$), and the average thickness of each layer ($$t$$)?

Accepted Answer

$$T = n 	imes t$$

Question 11

Which of the following is a function of the hypodermis?

Accepted Answer

Stores fat and anchors the skin to underlying structures

Question 12

A wound is healing poorly and remains open for several weeks. Which factor is most likely contributing to the delayed healing?

Accepted Answer

The tissue involved has poor regenerative capacity, such as cartilage

Question 13

Which of the following best describes the difference between serous and mucous membranes?

Accepted Answer

Serous membranes line closed body cavities and secrete serous fluid; mucous membranes line cavities open to the exterior and secrete mucus

Question 14

During the inflammatory phase of wound healing, which of the following events occurs first?

Accepted Answer

Damaged cells release cytokines, attracting immune cells

Question 15

Which cell type in the epidermis is primarily responsible for producing the pigment that gives skin its color?

Accepted Answer

Melanocyte

Question 16

A patient with a burn that destroys the epidermis and part of the dermis is at increased risk for infection. Which property of the skin is most compromised?

Accepted Answer

Barrier function against pathogens

Question 17

Which of the following best explains why scar tissue may impair the function of an organ after injury?

Accepted Answer

Scar tissue lacks the original tissue's specialized structure and function

Question 18

Which of the following is true regarding the immune response to tissue injury?

Accepted Answer

The initial inflammatory response is non-specific, while immune specificity develops over time

Question 19

If the area of a wound is $$A = l 	imes w$$, where $$l is $$the length and $$w is $$the width, what is the area of a wound that is 4 cm long and 2.5 cm wide?

Accepted Answer

$$A = 10\ \mathrm{cm}^2$$

Question 20

Which of the following best describes the role of granulation tissue in wound healing?

Accepted Answer

It replaces the clot and provides a foundation for new tissue growth
