Accepted Answer

Regeneration of epithelial cells

Question 3

Which characteristic distinguishes epithelial tissue from connective tissue?

Accepted Answer

Epithelial tissue is avascular but innervated

Question 4

A sample of tissue is observed to have cells with polarity, specialized contacts, and a high rate of regeneration. What type of tissue is most likely being observed?

Accepted Answer

Epithelial tissue

Question 5

Which of the following best describes the function of simple squamous epithelium in the alveoli of the lungs?

Accepted Answer

Rapid diffusion of gases

Question 6

A gland that releases its product by exocytosis without loss of cellular material is classified as:

Accepted Answer

Merocrine

Question 7

Which equation best represents the relationship between the rate of diffusion ($$R) $$and the thickness of the epithelial layer ($$d) in $$simple squamous epithelium?

Accepted Answer

A multicellular exocrine gland with a branched duct and secretory units arranged in sacs is classified as:

Accepted Answer

Compound alveolar gland

Question 10

Which of the following is a correct pairing of cell type and function in epithelial tissue?

Accepted Answer

Goblet cell – mucus secretion

Question 11

A biopsy reveals an epithelial tissue with multiple layers of flat cells at the surface and cuboidal cells at the base. What is the most likely function of this tissue?

Accepted Answer

Protection against abrasion

Question 12

Which of the following statements about endocrine glands is TRUE?

Accepted Answer

They secrete hormones directly into the bloodstream

Question 13

Which specialized contact is most important for preventing leakage between epithelial cells in the lining of the intestines?

Accepted Answer

Tight junctions

Question 14

A patient with a genetic defect in the reticular lamina would most likely experience problems with:

Accepted Answer

Support of epithelial tissue by connective tissue

Question 15

Which of the following best explains why stratified epithelial tissues are more durable than simple epithelial tissues?

Accepted Answer

Multiple layers provide increased protection against physical and chemical stress

Question 16

Which type of epithelial tissue is most likely to be found in the kidney tubules, where absorption and secretion are important?

Accepted Answer

Simple cuboidal epithelium

Question 17

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

Accepted Answer

$$D \propto n$$

Question 18

Which of the following is a key difference between unicellular and multicellular exocrine glands?

Accepted Answer

Unicellular glands consist of a single cell, while multicellular glands have multiple cells organized into secretory units

Question 19

A tissue sample from the trachea shows cells with cilia and varying heights, all attached to the basement membrane. What type of epithelium is this?

Accepted Answer

Pseudostratified columnar epithelium

Question 20

Which of the following best describes the role of the basal surface of epithelial tissue?

Accepted Answer

It anchors the epithelium to underlying connective tissue via the basal lamina
