Question 1

Which of the following best describes the function of the extracellular matrix (ECM) in connective tissue?

Accepted Answer

It provides a barrier to diffusion of substances and helps resist stretching and compressing forces.

Question 2

A patient presents with a skin wound that is slow to heal. Which tissue type is primarily responsible for wound healing and what process is involved?

Accepted Answer

Fibrous connective tissue; fibrosis

Question 3

Which type of epithelial cell is best suited for rapid diffusion of substances due to its thin, single-layered structure?

Accepted Answer

Simple squamous epithelium

Question 4

Which of the following junctions allows small molecules to pass directly between adjacent cells, facilitating cell-to-cell communication?

Accepted Answer

Gap junctions

Question 5

A gland that releases its product by exocytosis without damaging the cell is classified as which type of gland?

Accepted Answer

Merocrine gland

Question 6

Which connective tissue fiber type is most resistant to tension and pressure, and makes up 20-25% of the protein in the body?

Accepted Answer

Collagen fibers

Question 7

Which type of muscle tissue is found in the walls of hollow organs and is responsible for involuntary movement?

Accepted Answer

Smooth muscle tissue

Question 8

A person is exposed to cold temperatures, causing their body temperature to drop below normal. Which feedback mechanism is activated and what is the result?

Accepted Answer

Negative feedback; body temperature increases back to normal

Question 9

Which of the following is true regarding the epidermis of the skin?

Accepted Answer

It is avascular and composed of keratinized stratified squamous epithelium.

Question 10

Which type of cartilage is most abundant in the body and covers the ends of bones where they form joints?

Accepted Answer

Hyaline cartilage

Question 11

Which of the following best describes the function of osteoclasts in bone tissue?

Accepted Answer

They break down bone matrix for remodeling and calcium release.

Question 12

Which membrane lines cavities surrounding freely movable joints such as the hip and shoulder, and contains synoviocytes that secrete fluid?

Accepted Answer

Synovial membrane

Question 13

Which of the following best explains why simple squamous epithelium is not resistant to mechanical stresses?

Accepted Answer

It consists of a single thin layer of cells, making it fragile and easily damaged.

Question 14

Which type of connective tissue is primarily responsible for supporting small structures and is a part of the basement membrane?

Accepted Answer

Reticular tissue

Question 15

Which of the following equations correctly represents the relationship between the rate of diffusion ($$J) $$and the surface area ($$A) of $$simple squamous epithelium, assuming all other factors are constant?

Accepted Answer

$$J \propto A$$

Question 16

A patient with a genetic defect in collagen synthesis is likely to have problems with which tissue function?

Accepted Answer

Resisting tension and pressure in connective tissues

Question 17

Which of the following best describes the role of desmosomes in epithelial tissue?

Accepted Answer

They anchor cells together, allowing extracellular fluid to pass between cells.

Question 18

Which of the following is a correct statement about endocrine glands?

Accepted Answer

They lack ducts and secrete products directly into the blood.

Question 19

Which of the following cell types is responsible for producing substances required for bone maintenance?

Accepted Answer

Osteocytes

Question 20

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

Accepted Answer

They allow tissues to stretch and return to their original shape.
