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

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

Question 1

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

Accepted Answer

Contraction

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 permeability between cells, leading to loss of selective barriers

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

Which type of epithelial tissue is specialized for rapid diffusion and filtration, and is found lining the alveoli of the lungs?

Accepted Answer

Simple squamous epithelium

Question 5

A biopsy of a patient's bladder reveals an epithelium with multiple layers of cells that change from cuboidal to squamous as the bladder fills. What type of epithelium is this?

Accepted Answer

Transitional epithelium

Question 6

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 a surface.

Question 7

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, requiring constant renewal.

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

Accepted Answer

Collagen fibers

Question 10

A patient presents with swelling (edema) in the subcutaneous tissue after an injury. Which type of connective tissue is primarily responsible for soaking up the excess fluid?

Accepted Answer

Areolar connective tissue

Question 11

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 12

Which type of connective tissue is found in tendons and ligaments, and is characterized by parallel bundles of collagen fibers?

Accepted Answer

Dense regular connective tissue

Question 13

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

Accepted Answer

Synovial membrane

Question 14

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 15

Which type of connective tissue forms the soft internal skeleton (stroma) that supports lymphoid organs such as lymph nodes and spleen?

Accepted Answer

Reticular connective tissue

Question 16

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

Accepted Answer

Holocrine

Question 17

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

Accepted Answer

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

Question 18

Which of the following best explains why epithelial tissue is avascular but still able to receive nutrients?

Accepted Answer

Nutrients diffuse from underlying connective tissue through the basement membrane.

Question 19

A tissue sample shows a single layer of tall, closely packed cells with oval nuclei, some of which have cilia. This tissue is most likely found in which location?

Accepted Answer

Lining much of the respiratory tract

Question 20

Which of the following best describes the main function of adipose connective tissue?

Accepted Answer

Energy storage, insulation, and protection of organs
