Question 1

Which of the following best describes the function of the basement membrane in epithelial tissue?

Accepted Answer

It acts as a barrier between the epithelium and connective tissue, providing structural support and regulating exchange.

Question 2

A biopsy of a patient’s trachea reveals a tissue composed of a single layer of tall, rectangular cells, all attached to the basement membrane, but not all reaching the apical surface. Which type of epithelium is this?

Accepted Answer

Pseudostratified columnar epithelium

Question 3

Which of the following is a correct pairing of gland type and its method of secretion?

Accepted Answer

Apocrine gland – apical membrane pinches off with secretion

Question 4

A patient has a genetic defect affecting the production of glycosaminoglycans (GAGs) in connective tissue. Which of the following consequences is most likely?

Accepted Answer

Decreased water retention in the ground substance, leading to less cushioning and support

Question 5

Which connective tissue cell type is primarily responsible for producing the fibers and ground substance of the extracellular matrix?

Accepted Answer

Fibroblasts

Question 6

A tissue sample from the skin shows densely packed, parallel collagen fibers with little ground substance. What is the most likely type of connective tissue?

Accepted Answer

Dense regular connective tissue

Question 7

Which of the following best explains why epithelial tissue has a high regeneration capacity?

Accepted Answer

Epithelial cells are innervated and continually replaced due to frequent exposure to environmental stress.

Question 8

Which of the following is a function of areolar connective tissue?

Accepted Answer

Serves as the body’s 'packing material', supporting structures and binding tissues

Question 9

A patient presents with a tumor that is localized and does not invade surrounding tissues. What is the best term for this type of growth?

Accepted Answer

Benign neoplasia

Question 10

Which of the following best describes the role of mast cells in connective tissue?

Accepted Answer

They secrete heparin and histamine to mediate inflammation.

Question 11

Which of the following equations best represents the relationship between ground substance, protein fibers, and the extracellular matrix in connective tissue?

Accepted Answer

$$Extracellular\ matrix = Ground\ substance + Protein\ fibers$$

Question 12

A tissue sample from the urinary bladder shows cells that change shape depending on the degree of stretch. What is the most likely type of epithelium?

Accepted Answer

Transitional epithelium

Question 13

Which of the following is a correct function of reticular fibers in connective tissue?

Accepted Answer

Form a supportive framework (stroma) in lymphatic organs

Question 14

A patient with chronic inflammation has an increased number of plasma cells in their connective tissue. What is the primary function of these cells?

Accepted Answer

Produce antibodies to immobilize foreign material

Question 15

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

Accepted Answer

Endocrine glands secrete hormones directly into the blood; exocrine glands secrete substances onto epithelial surfaces via ducts.

Question 16

A patient’s tendon is injured. Which type of connective tissue is most likely affected, and what is its main structural component?

Accepted Answer

Dense regular connective tissue; collagen fibers

Question 17

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

Accepted Answer

Cartilage is avascular, so nutrients and cells required for repair are limited.

Question 18

Which of the following is a function of epithelial tissue that is NOT a function of connective tissue?

Accepted Answer

Physical protection from dehydration and abrasion

Question 19

A patient with a mutation affecting the protein elastin would most likely have problems with which of the following?

Accepted Answer

Ability of tissues to stretch and recoil

Question 20

Which of the following best describes the process of metaplasia?

Accepted Answer

A change from one mature epithelial cell type to another, often in response to environmental stress
