Question 1

Which of the following is NOT a primary function of epithelial tissue?

Accepted Answer

Contraction

Question 2

A patient has a mutation that prevents the formation of tight junctions in their epithelial cells. Which of the following is the most likely consequence?

Accepted Answer

Increased permeability between cells, allowing substances to pass freely between tissue compartments

Question 3

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

Accepted Answer

A structure composed of a basal lamina and a reticular lamina that supports and anchors the epithelium

Question 4

Why are epithelial tissues avascular, and how do they receive nutrients?

Accepted Answer

They lack blood vessels and receive nutrients by diffusion from underlying connective tissue

Question 5

Which of the following best explains why epithelial tissues have a high regenerative capacity?

Accepted Answer

They are frequently exposed to friction and environmental damage, requiring constant renewal

Question 6

A biopsy of a patient's trachea reveals a single layer of cells of varying heights, all attached to the basement membrane, with cilia on the apical surface. Which type of epithelium is this?

Accepted Answer

Pseudostratified ciliated columnar epithelium

Question 7

Which of the following is a function of goblet cells found in epithelial tissue?

Accepted Answer

Secretion of mucus to trap particles and lubricate surfaces

Question 8

Which type of epithelial tissue is best adapted for rapid diffusion and filtration, and where is it commonly found?

Accepted Answer

Simple squamous epithelium; found in lung alveoli and kidney glomeruli

Question 9

A gland that releases its product by exocytosis without losing any part of the cell is classified as which type?

Accepted Answer

Merocrine gland

Question 10

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

Accepted Answer

Endocrine glands are ductless and secrete hormones into the bloodstream, while exocrine glands secrete their products through ducts to body surfaces or cavities

Question 11

Which of the following connective tissue fibers provides the greatest tensile strength?

Accepted Answer

Collagen fibers

Question 12

A patient with edema is found to have excess fluid accumulating in a connective tissue that acts as a reservoir for water and salts. Which tissue is most likely involved?

Accepted Answer

Areolar connective tissue

Question 13

Which of the following best describes the function of proteoglycans in the ground substance of connective tissue?

Accepted Answer

They act as a molecular sieve, regulating the passage of substances between blood and cells

Question 14

Which type of connective tissue is specialized for fat storage and insulation, and where is it commonly found?

Accepted Answer

Adipose connective tissue; found under the skin and around organs

Question 15

A tendon is composed primarily of which type of connective tissue, and what is its main function?

Accepted Answer

Dense regular connective tissue; provides strong attachment between muscles and bones

Question 16

Which of the following best explains why stratified squamous epithelium is well-suited for areas subject to abrasion, such as the skin?

Accepted Answer

It consists of multiple layers of cells, with the apical layers constantly being replaced as they are worn away

Question 17

Which of the following best describes the difference between 'blast' and 'cyte' cells in connective tissue?

Accepted Answer

'Blast' cells are immature, actively dividing cells that synthesize matrix, while 'cyte' cells are mature and maintain the tissue

Question 18

A tissue sample from the urinary bladder shows cells that change shape from cuboidal to squamous as the bladder fills. What type of epithelium is this?

Accepted Answer

Transitional epithelium

Question 19

Which of the following best describes the function of reticular connective tissue?

Accepted Answer

Forms a soft internal skeleton that supports free blood cells in lymphoid organs

Question 20

A patient is diagnosed with rheumatoid arthritis, an autoimmune disease affecting connective tissue. Which structure is primarily targeted by the immune system in this condition?

Accepted Answer

Synovial membranes of joints
