$$\text{Viscosity} = f(\text{Water Content}, \text{Proteoglycans})$$

Question 1

Which of the following connective tissue types is most likely to be found in tendons and ligaments, and why?

Accepted Answer

Dense regular connective tissue, because its collagen fibers are aligned parallel to the direction of force, providing high tensile strength.

Question 2

Which structural element of connective tissue is primarily responsible for resisting tension and providing strength?

Accepted Answer

Collagen fibers

Question 3

A patient suffers a cartilage injury in the knee. Why does this injury heal slowly compared to a bone fracture?

Accepted Answer

Cartilage is avascular, so nutrients and repair cells reach it slowly.

Question 4

Which connective tissue cell type is most active in secreting matrix during tissue growth and repair?

Accepted Answer

Blast cells, such as fibroblasts, chondroblasts, and osteoblasts

Question 5

Which of the following best describes the function of adipose tissue in the human body?

Accepted Answer

It stores nutrients, insulates the body, and absorbs shock.

Question 6

Which connective tissue type is most likely to be found in the walls of large arteries, and what property does it provide?

Accepted Answer

Elastic connective tissue; allows stretch and recoil to accommodate blood flow.

Question 7

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

Accepted Answer

Providing structural support for organs

Question 8

During tissue repair, which process results in the restoration of original tissue function?

Accepted Answer

Regeneration

Question 9

Which embryonic germ layer gives rise to both muscle and connective tissues?

Accepted Answer

Mesoderm

Question 10

A patient develops adhesions after abdominal surgery. What is a possible consequence of these adhesions?

Accepted Answer

Progressive organ failure due to impaired movement and function

Question 11

Which of the following equations best represents the relationship between the viscosity of ground substance and water content in connective tissue?

Accepted Answer

$$	ext{Viscosity} = f(	ext{Water Content}, 	ext{Proteoglycans})$$

Question 12

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

Accepted Answer

Skeletal muscle

Question 13

Which connective tissue fiber type allows tissues to stretch and then return to their original shape?

Accepted Answer

Elastic fibers

Question 14

Which of the following best explains why cardiac muscle and nervous tissue have poor regenerative capacity?

Accepted Answer

Their cells rarely divide after development.

Question 15

Which covering and lining membrane is composed of keratinized stratified squamous epithelium attached to a thick layer of connective tissue?

Accepted Answer

Cutaneous membrane

Question 16

Which cell type in connective tissue is responsible for initiating local inflammatory responses against foreign microorganisms?

Accepted Answer

Mast cells

Question 17

Which of the following is a correct sequence of events in tissue repair after a nonextensive skin wound?

Accepted Answer

Inflammation, organization, regeneration

Question 18

Which connective tissue type forms the stroma that supports blood cells in lymph nodes, spleen, and bone marrow?

Accepted Answer

Reticular connective tissue

Question 19

Which of the following best describes the matrix of bone tissue?

Accepted Answer

Gel-like ground substance calcified with inorganic salts and collagen fibers

Question 20

Which of the following is a function of serous membranes in the body?

Accepted Answer

They cover internal organs and secrete slippery fluid to reduce friction.
