Question 1

Which of the following best describes the main function of epithelial tissue in the human body?

Accepted Answer

Covering body surfaces and lining cavities to provide protection and selective permeability

Question 2

A biopsy sample from a patient's trachea reveals tissue with cilia on its apical surface and cells arranged in a single layer, though nuclei appear at different heights. Which tissue type is most likely present?

Accepted Answer

Pseudostratified columnar epithelium

Question 3

Which of the following best explains why cartilage heals more slowly than bone after injury?

Accepted Answer

Cartilage is avascular, so it lacks a direct blood supply for nutrient delivery and waste removal.

Question 4

A patient suffers a deep cut that damages both the epidermis and dermis. Which of the following best describes the initial inflammatory response in the affected tissue?

Accepted Answer

Mast cells release histamine, increasing capillary permeability and attracting immune cells.

Question 5

Which of the following is a correct pairing of tissue type and its typical location?

Accepted Answer

Adipose tissue – subcutaneous layer beneath the skin

Question 6

Which of the following best describes the relationship between the structure and function of skeletal muscle tissue?

Accepted Answer

Skeletal muscle fibers are long, cylindrical, and multinucleated, enabling voluntary, forceful contractions.

Question 7

A histology slide shows tissue with abundant collagen fibers arranged in parallel bundles and very few blood vessels. Which tissue is most likely being observed?

Accepted Answer

Dense regular connective tissue

Question 8

Which of the following best explains why the epidermis is considered avascular?

Accepted Answer

It lacks blood vessels and receives nutrients by diffusion from the underlying dermis.

Question 9

Which of the following best describes the function of fibroblasts in connective tissue?

Accepted Answer

They produce and secrete the extracellular matrix, including collagen and elastic fibers.

Question 10

A patient with a genetic defect in the production of elastin would most likely experience which of the following symptoms?

Accepted Answer

Reduced flexibility of skin and blood vessels, leading to stiffness and hypertension

Question 11

Which of the following best describes the process of tissue repair after injury?

Accepted Answer

Inflammation, organization (formation of granulation tissue), and regeneration or fibrosis

Question 12

Which of the following is a key difference between nervous tissue and muscle tissue?

Accepted Answer

Nervous tissue transmits electrical signals, while muscle tissue contracts to produce movement.

Question 13

Which of the following best explains why stratified squamous epithelium is found in areas subject to abrasion, such as the skin and esophagus?

Accepted Answer

Its multiple layers provide protection against mechanical stress and prevent water loss.

Question 14

A tissue sample is observed to have cells with a basal surface attached to a basement membrane and an apical surface exposed to a lumen. Which of the following best describes this tissue?

Accepted Answer

Epithelial tissue

Question 15

Which of the following best describes the role of mast cells in the inflammatory process?

Accepted Answer

They release histamine and other mediators to increase blood flow and attract immune cells.

Question 16

Which of the following is a correct sequence of events in the healing of a skin wound?

Accepted Answer

Inflammation, formation of granulation tissue, regeneration of epithelium

Question 17

Which of the following best explains why the basement membrane is important in epithelial tissues?

Accepted Answer

It anchors the epithelium to underlying connective tissue and regulates cell behavior.

Question 18

A patient presents with a burn that destroys the epidermis and damages the dermis. Which of the following best describes the expected healing process?

Accepted Answer

Fibrosis will likely occur, resulting in scar tissue formation due to damage to the dermis.

Question 19

Which of the following best describes the function of collagen fibers in connective tissue?

Accepted Answer

They provide tensile strength and resist stretching.

Question 20

Which of the following best explains why simple cuboidal epithelium is well-suited for forming the walls of kidney tubules?

Accepted Answer

Its cube-shaped cells provide space for organelles involved in absorption and secretion.
