Question 1

Which of the following best explains why simple squamous epithelium is found lining the alveoli of the lungs and capillaries?

Accepted Answer

Its single layer of flat cells allows for rapid diffusion of gases and nutrients.

Question 2

A patient presents with a burn that is red, painful, and has blisters. Which degree of burn does this most likely represent, and what layers of skin are affected?

Accepted Answer

Second-degree burn; epidermis and part of the dermis are affected.

Question 3

Which of the following is a key structural feature of epithelial tissue that allows it to function as a barrier and interface between different environments?

Accepted Answer

Closely packed cells with tight junctions and desmosomes

Question 4

A biopsy of a gland reveals that its secretions are released by exocytosis without loss of cellular material. Which type of gland is this, and what is the name of this secretion method?

Accepted Answer

Exocrine gland; merocrine secretion

Question 5

Which of the following best describes the function and location of pseudostratified ciliated columnar epithelium?

Accepted Answer

Secretion and movement of mucus in the upper respiratory tract

Question 6

A tissue sample shows multiple layers of cells with the apical layer being flat and dead, containing keratin. Where is this tissue most likely found, and what is its primary function?

Accepted Answer

Epidermis of the skin; protection against abrasion and water loss

Question 7

Which of the following statements about the basement membrane is correct?

Accepted Answer

It consists of glycoproteins from epithelial cells and reticular fibers from connective tissue.

Question 8

A patient is diagnosed with malignant melanoma. Which of the following characteristics is most concerning for this type of skin cancer?

Accepted Answer

It arises from melanocytes and can rapidly invade underlying tissues.

Question 9

Which of the following best explains why transitional epithelium is found lining the urinary bladder?

Accepted Answer

Its cells can change shape to accommodate stretching as the bladder fills.

Question 10

A glandular tissue is observed to have ducts that branch repeatedly and secretory units that are both tubular and alveolar in shape. How would this gland be classified?

Accepted Answer

Compound tubuloalveolar gland

Question 11

Which of the following equations correctly represents the calculation of the percentage of body surface area burned using the 'Rule of Nines' for an adult?

Accepted Answer

$$Total\,Burn\,Area = (Head\,and\,Neck) + (Upper\,Limbs) + (Trunk) + (Lower\,Limbs) + (Perineum)$$

Question 12

Which of the following is a function of goblet cells found in pseudostratified columnar epithelium?

Accepted Answer

Production and secretion of mucin to trap particles

Question 13

A tissue sample from the kidney tubules is examined under a microscope. Which type of epithelial tissue is most likely present, and what is its main function?

Accepted Answer

Simple cuboidal epithelium; absorption and secretion

Question 14

Which of the following best describes the difference between endocrine and exocrine glands?

Accepted Answer

Endocrine glands release hormones into the blood; exocrine glands secrete products onto surfaces or into ducts.

Question 15

Which of the following is a characteristic of stratified squamous epithelium that makes it suitable for areas subject to abrasion?

Accepted Answer

It has multiple layers of cells, with the apical layer being flat and often keratinized.

Question 16

A patient with a third-degree burn does not feel pain in the affected area. What is the most likely explanation for this?

Accepted Answer

The burn has destroyed the nerve endings in the skin.

Question 17

Which of the following best explains why epithelial tissue is avascular but innervated?

Accepted Answer

Epithelial tissue receives nutrients by diffusion from underlying connective tissue and contains nerve endings for sensation.

Question 18

Which of the following scenarios best illustrates the principle of 'structure determines function' in epithelial tissues?

Accepted Answer

Stratified squamous epithelium in the skin provides protection against abrasion due to its multiple layers.

Question 19

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

Accepted Answer

Connective tissue: supports, protects, and binds other tissues

Question 20

A patient has a mole that is asymmetrical, has irregular borders, and has changed color and size. According to the ABCD method, what is the most appropriate next step?

Accepted Answer

Seek immediate medical evaluation for possible melanoma.
