Accepted Answer

Stratified squamous epithelium

Question 3

Which of the following statements about connective tissue is TRUE?

Accepted Answer

It arises from mesenchyme and contains varying degrees of vascularity.

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 injuries heal slowly in adults?

Accepted Answer

Cartilage is avascular and relies on diffusion for nutrient delivery.

Question 6

Which mode of secretion involves the entire secretory cell rupturing to release its product?

Accepted Answer

Holocrine

Question 7

A biopsy reveals tissue with cells that are spindle-shaped, have one nucleus, and lack visible striations. This tissue is most likely:

Accepted Answer

Smooth muscle

Question 8

Which of the following is a function of areolar connective tissue?

Accepted Answer

Universal packing material between other tissues

Question 9

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

Accepted Answer

Endocrine glands are ductless and release hormones into the blood; exocrine glands secrete products onto body surfaces or into cavities.

Question 10

Which of the following cell junctions is most important for preventing molecules from passing between adjacent epithelial cells?

Accepted Answer

Tight junctions
