Question 1

Which of the following best describes the function of tight junctions in epithelial tissue?

Accepted Answer

They form a selectively permeable barrier that prevents diffusion of fluids and solutes between cells.

Question 2

A patient presents with a burn that has destroyed the epidermis and underlying connective tissue. Which tissue type is most likely to regenerate well after injury?

Accepted Answer

Epithelial tissue

Question 3

Which specialized cell in connective tissue proper is responsible for secreting ground substance and protein fibers?

Accepted Answer

Fibroblast

Question 4

Which type of cartilage is found in the external ear and epiglottis, and is characterized by its flexibility due to elastic fibers?

Accepted Answer

Elastic cartilage

Question 5

A researcher is studying the movement of nutrients into epithelial cells. Which surface is primarily involved in absorption?

Accepted Answer

Apical surface

Question 6

Which of the following is a correct statement about the vascularity of epithelial tissue?

Accepted Answer

Epithelial tissue is avascular and receives nutrients by diffusion.

Question 7

Which connective tissue type is most likely to be found in tendons and is characterized by tightly packed, parallel collagen fibers?

Accepted Answer

Dense regular connective tissue

Question 8

A patient with a genetic defect in cell adhesion molecules (CAMs) would most likely experience problems with which of the following?

Accepted Answer

Cell-to-cell attachment and tissue integrity

Question 9

Which of the following equations best represents the relationship between the components of connective tissue proper?

Accepted Answer

$$Matrix = Extracellular\ Protein\ Fibers + Ground\ Substance$$

Question 10

Which type of muscle tissue is striated, multinucleate, and under voluntary control?

Accepted Answer

Skeletal muscle tissue

Question 11

Which of the following best explains why cartilage heals poorly after injury?

Accepted Answer

Chondrocytes produce antiangiogenesis factor, making cartilage avascular.

Question 12

Which membrane lines cavities that do not open to the exterior and consists of a parietal and visceral portion separated by fluid?

Accepted Answer

Serous membrane

Question 13

A biopsy reveals tissue with cells arranged in a single layer of tall, slender rectangles. Which type of epithelium is this?

Accepted Answer

Simple columnar epithelium

Question 14

Which of the following is a function of neuroglia in nervous tissue?

Accepted Answer

Supporting and protecting neurons

Question 15

Which equation correctly represents the proportion of bone matrix components?

Accepted Answer

$$Bone\ Matrix = \frac{2}{3} Calcified\ Salts + \frac{1}{3} Collagen\ Fibers$$

Question 16

Which of the following is a cardinal sign of inflammation?

Accepted Answer

Redness

Question 17

Which type of gland releases hormones directly into the bloodstream?

Accepted Answer

Endocrine gland

Question 18

A patient with a deficiency in mast cells would most likely have impaired:

Accepted Answer

Inflammatory response

Question 19

Which of the following best describes the function of reticular fibers in connective tissue?

Accepted Answer

They form a network that supports the structure of organs and resists forces in many directions.

Question 20

Which of the following is true regarding regeneration after tissue injury?

Accepted Answer

Epithelial and smooth muscle tissues regenerate well.
