Question 1

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

Accepted Answer

Support

Question 2

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

Accepted Answer

Increased risk of dehydration due to loss of selective permeability

Question 3

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

Accepted Answer

It consists of a basal lamina and a reticular lamina, providing support and acting as a selective filter.

Question 4

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

Accepted Answer

Simple squamous epithelium; found in lung alveoli and kidney glomeruli

Question 5

A biopsy of a patient's bladder reveals an epithelium with cuboidal basal cells and apical cells that flatten as the bladder fills. What type of epithelium is this?

Accepted Answer

Transitional epithelium

Question 6

Which of the following best explains why epithelial tissues are avascular but can still receive nutrients?

Accepted Answer

Nutrients diffuse from underlying connective tissue through the basement membrane.

Question 7

Which of the following is a key 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 8

A gland that releases its product by exocytosis without damaging the cell is classified as which type?

Accepted Answer

Merocrine

Question 9

Which connective tissue fiber type provides the greatest tensile strength?

Accepted Answer

Collagen fibers

Question 10

A patient with rheumatoid arthritis is experiencing joint pain due to immune attack on which specific connective tissue structure?

Accepted Answer

Synovial membrane

Question 11

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

Accepted Answer

They act as a molecular sieve, regulating the passage of substances through the ground substance.

Question 12

Which type of connective tissue acts as a reservoir for water and salts and is the primary site of edema during inflammation?

Accepted Answer

Areolar connective tissue

Question 13

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 14

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

Accepted Answer

They are frequently exposed to friction and hostile environments, necessitating rapid replacement of lost cells.

Question 15

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 secrete matrix; 'cyte' cells are mature, less active cells that maintain the tissue.

Question 16

A tissue sample shows a single layer of tall, closely packed cells with oval nuclei aligned at the same level, and microvilli on the apical surface. Which type of epithelium is this, and what is its primary function?

Accepted Answer

Simple columnar epithelium; absorption and secretion

Question 17

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 18

A multicellular exocrine gland that releases its product by the rupture of entire cells is classified as which type?

Accepted Answer

Holocrine

Question 19

Which of the following equations best represents the relationship between the number of cell layers ($$n) $$and the type of epithelial tissue?

Accepted Answer

$$n = 1$$ \Rightarrow 	ext{simple epithelium};\ n \u003e 1 \Rightarrow 	ext{stratified epithelium}$

Question 20

A patient presents with swelling (edema) in the subcutaneous tissue after an injury. Which connective tissue is primarily responsible for absorbing the excess fluid, and what property allows it to do so?

Accepted Answer

Areolar connective tissue; loose arrangement of fibers and abundant ground substance
