Accepted Answer

Pseudostratified columnar epithelium

Question 3

Which intercellular junction is primarily responsible for preventing the passage of water and solutes between adjacent epithelial cells?

Accepted Answer

Tight junction

Question 4

A patient suffers a tendon injury. Which type of connective tissue is primarily affected?

Accepted Answer

Dense regular connective tissue

Question 5

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

Accepted Answer

Cartilage is avascular, while bone has a rich blood supply

Question 6

Which glandular secretion method involves the entire cell rupturing to release its product?

Accepted Answer

Holocrine

Question 7

A biopsy reveals a 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 8

Which connective tissue fiber type is most responsible for providing tensile strength in tendons?

Accepted Answer

Collagen fibers

Question 9

Which of the following equations best represents the relationship between tissue regeneration rate ($$R$$), blood supply ($$B$$), and cell division rate ($$D$$)? Assume regeneration rate is directly proportional to both blood supply and cell division rate.

Accepted Answer

$$R = B 	imes D$$

Question 10

Which of the following best describes the sequence of events in tissue repair after an injury?

Accepted Answer

Inflammation, granulation tissue formation, regeneration

Question 11

A patient with liver damage is found to have excessive scar tissue formation. Which process is primarily responsible for this outcome?

Accepted Answer

Fibrosis

Question 12

Accepted Answer

Fibroblasts

Question 13

Which membrane type lines body cavities that do NOT open to the exterior and reduces friction between organs?

Accepted Answer

Serous membrane

Question 14

Which of the following best describes the main function of microvilli on epithelial cells?

Accepted Answer

Increase surface area for absorption

Question 15

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

Accepted Answer

Endocrine glands secrete hormones directly into the bloodstream; exocrine glands secrete products onto body surfaces or into ducts.

Question 16

Which of the following connective tissue cells is most likely to increase in number during an allergic reaction?

Accepted Answer

Mast cells

Question 17

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

Accepted Answer

Transitional epithelium

Question 18

Which of the following best explains why areolar connective tissue is considered the 'universal packing material' in the body?

Accepted Answer

It provides a reservoir of water and salts for surrounding tissues

Question 19

Which of the following equations best represents the relationship between the total number of epithelial cells ($$N$$), the rate of cell division ($$r$$), and time ($$t$$), assuming exponential growth?

Accepted Answer

$$N = N_0$ e$$^{rt}$$

Question 20

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

Accepted Answer
