Epithelial cells divide regularly.

Question 8

Which feature of simple squamous epithelium makes it ideal for rapid diffusion?

Accepted Answer

It is very thin.

Question 9

Which type of epithelial tissue is most likely to be found lining the ducts of glands?

Accepted Answer

Simple cuboidal epithelium

Question 10

Which of the following is a primary function of goblet cells?

Accepted Answer

Lubricating and protecting the epithelium

Question 11

Which type of multicellular gland needs to be completely regenerated each time it secretes product?

Accepted Answer

Holocrine

Question 12

Which part of connective tissue takes up most of the volume?

Extracellular Matrix

Question 13

Which of the following best describes the difference between collagen fibers and reticular fibers in connective tissue?

Accepted Answer

Collagen fibers are long and straight while reticular fibers are branched.

Question 14

Which type of connective tissue is best suited to resist force from multiple directions, such as in the dermis of the skin?

Accepted Answer

Dense irregular connective tissue

Question 15

Which of the following is a likely complication of Marfan syndrome, a genetic condition affecting elastic fibers in the ECM?
