$$\frac{\text{Waist circumference (cm)}}{\text{Hip circumference (cm)}}$$

Question 1

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

Accepted Answer

It surrounds cells and can be thick gel, fluid, or solid, providing structural support and regulating development.

Question 2

Which type of epithelial tissue is most suited for rapid diffusion and is found lining blood vessels and alveoli?

Accepted Answer

Simple squamous epithelium

Question 3

A patient presents with a burn that destroys the epidermis and dermis. Which tissue repair process is most likely to occur?

Accepted Answer

Fibrosis resulting in scar tissue formation

Question 4

Which cell type is responsible for secreting hyaluronan and protein fibers in connective tissue proper?

Accepted Answer

Fibroblast

Question 5

Which of the following is a function of dense regular connective tissue?

Accepted Answer

Forms tendons and ligaments due to tightly packed collagen fibers

Question 6

Which type of cartilage is most abundant and serves as a precursor to the fetal skeleton?

Accepted Answer

Hyaline cartilage

Question 7

A patient with chronic inflammation is found to have elevated C-reactive protein (CRP) levels. What does this indicate?

Accepted Answer

Acute phase inflammatory response

Question 8

Which of the following best describes the difference between benign and malignant tumors?

Accepted Answer

Malignant tumors invade surrounding tissues and can metastasize; benign tumors do not.

Question 9

Which of the following is true regarding the vascularity of connective tissue types?

Accepted Answer

Dense regular connective tissue has few blood vessels, resulting in slow healing.

Question 10

Which of the following cell junctions allows direct passage of ions and small molecules between adjacent epithelial cells?

Accepted Answer

Gap junctions

Question 11

Which formula correctly represents the calculation of waist-to-hip ratio, a measure relevant to adipose tissue distribution?

Accepted Answer

$$\frac{	ext{Waist circumference (cm)}}{	ext{Hip circumference (cm)}}$$

Question 12

Which connective tissue type is most abundant and functions to attach skin, fill spaces, and surround/support organs?

Accepted Answer

Areolar connective tissue

Question 13

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

Accepted Answer

Storing fat for energy

Question 14

Which cell type is responsible for bone resorption?

Accepted Answer

Osteoclast

Question 15

A patient with asthma is experiencing tissue inflammation. Which chemical mediator is most likely elevated during the acute phase?

Accepted Answer

Histamine

Question 16

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

Accepted Answer

Forms the inner framework of organs such as lymph nodes and spleen

Question 17

Which type of muscle tissue is striated, voluntary, and contains multiple nuclei per cell?

Accepted Answer

Skeletal muscle

Question 18

Which of the following is a characteristic of neurons in nervous tissue?

Accepted Answer

They conduct nerve impulses (action potentials) and require a continuous supply of oxygen.

Question 19

Which of the following best explains why cartilage heals poorly compared to other connective tissues?

Accepted Answer

Cartilage is avascular and relies on diffusion of nutrients, limiting repair capacity.

Question 20

Which of the following tissue modifications involves an increase in cell size without an increase in cell number?

Accepted Answer

Hypertrophy
