Question 1

Which of the following best describes the function of serous membranes in the human body?

Accepted Answer

They secrete watery serous fluid to reduce friction between organs within closed body cavities.

Question 2

A patient presents with inflammation of the pleura, resulting in painful breathing due to friction between the layers. Which condition does this describe, and what is the underlying cause?

Accepted Answer

Pleurisy; caused by lack of serous fluid between the pleural layers.

Question 3

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

Accepted Answer

Stratum basale

Question 4

Which of the following is NOT a function of the integumentary system?

Accepted Answer

Production of red blood cells

Question 5

A synovial membrane differs from epithelial membranes because it:

Accepted Answer

Does not contain any epithelium and secretes viscous synovial fluid

Question 6

Which pigment is produced by melanocytes and provides protection against UV radiation?

Accepted Answer

Melanin

Question 7

A burn patient is at risk for dehydration and electrolyte imbalance. Which layer of the skin, if damaged, most directly contributes to this risk?

Accepted Answer

Dermis

Question 8

Which of the following correctly matches the membrane type with its location?

Accepted Answer

Cutaneous membrane – forms the external covering of the body

Question 9

Which layer of the skin contains most of the appendages such as sweat glands and hair follicles?

Accepted Answer

Dermis

Question 10

A patient with jaundice presents with a yellowish skin tone. Which pigment is responsible for this coloration?

Accepted Answer

Bilirubin

Question 11

Which of the following equations best represents the relationship between the layers of the epidermis from deepest to most superficial?

Accepted Answer

$$Stratum\ basale \rightarrow Stratum\ spinosum \rightarrow Stratum\ granulosum \rightarrow Stratum\ lucidum \rightarrow Stratum\ corneum$$

Question 12

Which of the following is a real-life consequence of damage to the stratum basale?

Accepted Answer

Impaired regeneration of the epidermis, leading to chronic wounds

Question 13

Which membrane type is most likely to be involved in the transmission of respiratory infections?

Accepted Answer

Mucous membrane

Question 14

Which of the following best explains why the cutaneous membrane is considered a 'dry' membrane?

Accepted Answer

It is exposed to air and does not line internal body cavities.

Question 15

Which of the following is the correct function of goblet cells found in mucous membranes?

Accepted Answer

Secrete mucus for lubrication and trapping pathogens

Question 16

A patient with cyanosis has a bluish skin tone. What is the most likely physiological cause?

Accepted Answer

Decreased oxygenation of hemoglobin in blood vessels of the dermis

Question 17

Which of the following best describes the lamina propria?

Accepted Answer

A layer of loose areolar connective tissue underlying the epithelium in mucous membranes

Question 18

Which of the following is a multi-step process that occurs when the skin is exposed to UV radiation?

Accepted Answer

Melanocytes increase melanin production, which is transferred to keratinocytes to shield DNA from UV damage.

Question 19

Which of the following is the correct equation for the function of the acid mantle produced by the skin?

Accepted Answer

$$Acid\ Mantle = Sebum + Sweat$$
