Fibroblast

Question 4

A tissue sample shows cells storing large droplets of fat with nuclei pushed to the periphery. Which type of connective tissue is this?

Accepted Answer

Adipose connective tissue

Question 5

Which of the following equations best represents the composition of the extracellular matrix (ECM) in connective tissue?

Accepted Answer

$$ECM = 	ext{Protein\ fibers} + 	ext{Ground\ substance}$$

Question 6

Which connective tissue cell type is derived from monocytes and is responsible for phagocytosis?

Accepted Answer

Macrophage

Question 7

A tissue sample from the dermis of the skin shows collagen fibers arranged in multiple directions. What type of connective tissue is this?

Accepted Answer

Dense irregular connective tissue

Question 8

Which of the following best explains why areolar connective tissue is found beneath epithelial tissues?

Accepted Answer

It provides support, cushions, and allows immune defense

Question 9

If a patient has a deficiency in elastic fibers, which physiological function would be most affected?

Accepted Answer

Ability of tissues to recoil after stretching

Question 10

Which connective tissue type is most likely to be found in lymphoid organs such as the spleen and lymph nodes, providing a supportive network for immune cells?

Accepted Answer

Reticular connective tissue

Question 11

A tendon is composed primarily of which type of connective tissue, and what is the main arrangement of its fibers?

Accepted Answer

Dense regular connective tissue; parallel collagen fibers

Question 12

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

Accepted Answer

Initiating voluntary muscle contraction

Question 13

Which cell type in connective tissue is responsible for promoting inflammation and allergic responses?

Accepted Answer

Mast cell

Which embryonic tissue gives rise to all connective tissues in the body?

Accepted Answer

Mesenchyme

Question 15

A researcher is studying a tissue with the following characteristics: highly vascularized, contains fibroblasts, adipocytes, and a loose arrangement of all three fiber types. Which tissue is being described?

Accepted Answer

Areolar connective tissue

Question 16

Which of the following best explains the difference between fibroblasts and fibrocytes?

Accepted Answer

Fibroblasts are active in secreting ECM, while fibrocytes are less active

Question 17

Which of the following equations correctly represents the relationship between the main components of connective tissue?

Accepted Answer

$$	ext{Connective\ Tissue} = 	ext{Cells} + 	ext{Extracellular\ Matrix}$$

Question 18

Which connective tissue cell type is primarily responsible for storing energy in the form of triglycerides?

Accepted Answer

Adipocyte

Question 19

A tissue sample contains a network of reticular fibers and supports many lymphocytes. Which function does this tissue most likely serve?

Accepted Answer

Supporting immune cells in lymphoid organs

Question 20

Which of the following best describes the role of ground substance in connective tissue?

Accepted Answer

It fills the space between cells and fibers, providing a medium for nutrient and waste exchange
