Q: Which of the following equations correctly represents the calculation of the waist-to-hip ratio, which is used to assess adipose tissue distribution?

$$\frac{\text{waist circumference}}{\text{hip circumference}}$$

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 cell type is primarily responsible for producing protein fibers in connective tissue proper?

Accepted Answer

Fibroblast

Question 3

A patient presents with a wound that heals by forming scar tissue rather than regenerating the original tissue. Which process is primarily responsible for this type of repair?

Accepted Answer

Fibrosis

Question 4

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

Accepted Answer

Simple squamous

Question 5

Which of the following is a function of mast cells in connective tissue?

Accepted Answer

Releasing chemicals that mediate inflammation, such as histamine

Question 6

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

Accepted Answer

Hyaline cartilage

Question 7

A tissue sample shows tightly packed bundles of collagen fibers with few blood vessels and many fibroblasts. Which type of connective tissue is this?

Accepted Answer

Dense regular connective tissue

Question 8

Which of the following best explains why bone tissue is stronger but less flexible than cartilage?

Accepted Answer

Bone is calcified with calcium and phosphate salts, which resist shattering.

Question 9

Which of the following is a correct description of the function of simple cuboidal epithelial tissue?

Accepted Answer

It contains large spherical central nuclei and is found in glands, functioning in secretion and absorption.

Question 10

Which of the following equations correctly represents the calculation of the waist-to-hip ratio, which is used to assess adipose tissue distribution?

Accepted Answer

$$\frac{	ext{waist circumference}}{	ext{hip circumference}}$$

Question 11

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

Accepted Answer

They conduct nerve impulses (action potentials) and have a cell body, dendrites, and axon.

Question 12

During the inflammatory response, which chemical is primarily responsible for vasodilation and increased blood flow to the injured area?

Accepted Answer

Histamine

Question 13

Which type of membrane lines body cavities that do not open to the exterior and consists of visceral and parietal layers?

Accepted Answer

Serous membrane

Question 14

A patient with asthma is experiencing tissue modification. Which term best describes an increase in the number of cells in a tissue due to chronic inflammation?

Accepted Answer

Hyperplasia

Question 15

Which of the following is true regarding the difference between benign and malignant tumors?

Accepted Answer

Malignant tumors invade surrounding tissues and can metastasize.

Question 16

Which cell type is responsible for bone formation by producing the bone matrix?

Accepted Answer

Osteoblast

Question 17

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

Accepted Answer

Areolar connective tissue

Question 18

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

Accepted Answer

They anchor adjacent cells together, providing mechanical strength.

Question 19

Which of the following is a correct statement about the vascular supply of cartilage?

Accepted Answer

Cartilage is avascular due to secretion of anti-angiogenesis factors by chondrocytes.

Question 20

Which of the following best describes the role of gap junctions in epithelial tissue?

Accepted Answer

They allow direct communication between adjacent cells by permitting the passage of ions and small molecules.
