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

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

Question 1

Which of the following statements best explains why cartilage injuries heal slowly compared to bone injuries?

Accepted Answer

Cartilage is avascular, so it receives nutrients by diffusion from the perichondrium, limiting its ability to repair.

Question 2

A patient presents with a wound that heals with scar tissue rather than restoration of the original tissue. Which process is primarily responsible for this outcome?

Accepted Answer

Fibrosis

Question 3

Which connective tissue type is most likely to be found in tendons and ligaments, and what property does it provide?

Accepted Answer

Dense regular connective tissue; provides high tensile strength in one direction

Question 4

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

Accepted Answer

Generating nerve impulses

Question 5

A biopsy of a lymph node reveals a mesh-like stroma supporting blood cells. Which connective tissue is most likely present?

Accepted Answer

Reticular connective tissue

Question 6

Which cell type in connective tissue is responsible for actively secreting the extracellular matrix during tissue growth?

Accepted Answer

Blast cells

Question 7

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

Accepted Answer

Unstructured gel-like material containing interstitial fluid, cell adhesion proteins, and proteoglycans

Question 8

Which connective tissue fiber type is most responsible for providing high tensile strength?

Accepted Answer

Collagen fibers

Question 9

A patient with a heart attack develops scar tissue in the myocardium. What is a likely consequence of this fibrosis?

Accepted Answer

Loss of volume capacity and impaired muscle contraction

Question 10

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

Accepted Answer

Mesoderm

Question 11

Which of the following tissues has virtually no functional regenerative capacity?

Accepted Answer

Cardiac muscle

Question 12

Which membrane lines body cavities that are open to the exterior and is bathed by secretions?

Accepted Answer

Mucous membrane

Question 13

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

Accepted Answer

Skeletal muscle

Question 14

Which connective tissue is most likely to be found in the walls of large arteries, allowing them to stretch and recoil?

Accepted Answer

Elastic connective tissue

Question 15

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

Accepted Answer

Inflammation sets the stage, organization restores blood supply, then regeneration and fibrosis effect permanent repair

Question 16

Which connective tissue type is most abundant and widely distributed in the body?

Accepted Answer

Connective tissue

Question 17

Which of the following best describes the role of mast cells in connective tissue?

Accepted Answer

They initiate local inflammatory responses against foreign microorganisms.

Question 18

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 19

Which of the following is a function of blood as a connective tissue?

Accepted Answer

Transporting nutrients, wastes, gases, and other substances

Question 20

A patient with adhesions after surgery experiences organs sticking to neighboring structures. What is a possible consequence of this?

Accepted Answer

Progressive failure of the organ due to impaired movement and function
