$$\text{Connective Tissue} = \text{Cells} + \text{Extracellular Matrix (Ground Substance + Fibers)}$$

Question 1

Which of the following is NOT a characteristic that distinguishes connective tissue from other primary tissue types?

Accepted Answer

Connective tissues are composed primarily of tightly packed cells with little extracellular matrix.

Question 2

A patient suffers a tendon injury. Which connective tissue property explains why this injury may take a long time to heal?

Accepted Answer

Tendons are composed of dense regular connective tissue, which is poorly vascularized.

Question 3

Which type of connective tissue fiber is most responsible for providing high tensile strength to tissues such as tendons?

Accepted Answer

Collagen fibers

Question 4

Which cell type is primarily responsible for secreting the extracellular matrix in cartilage during growth?

Accepted Answer

Chondroblasts

Question 5

A biopsy of a patient’s spleen reveals a mesh-like network supporting blood cells. Which connective tissue is most likely present?

Accepted Answer

Reticular connective tissue

Question 6

Which of the following best describes the function of brown adipose tissue?

Accepted Answer

Generates heat by burning lipid fuels without producing ATP

Question 7

Which connective tissue type is found in the walls of large arteries and allows for stretch and recoil?

Accepted Answer

Elastic connective tissue

Question 8

A patient with a spinal injury has damage to the intervertebral discs. Which type of cartilage is primarily affected?

Accepted Answer

Fibrocartilage

Question 9

Which of the following statements about bone tissue is TRUE?

Accepted Answer

Bone tissue contains more collagen than cartilage and is highly vascularized.

Question 10

Which connective tissue is considered the most atypical because it is a fluid?

Accepted Answer

Blood

Question 11

Which muscle tissue type is under voluntary control and contains multinucleate, striated cells?

Accepted Answer

Skeletal muscle

Question 12

Which of the following is a function of nervous tissue?

Accepted Answer

Transmitting electrical signals from sensory receptors to effectors

Question 13

Which membrane type lines body cavities that are open to the exterior, such as the digestive and respiratory tracts?

Accepted Answer

Mucous membrane

Question 14

During tissue repair, which process results in the replacement of destroyed tissue with the same kind of tissue, restoring original function?

Accepted Answer

Regeneration

Question 15

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

Accepted Answer

Cardiac muscle

Question 16

A patient develops a scar in the heart muscle after a heart attack. Which of the following is a likely consequence?

Accepted Answer

The scar tissue may impair the heart’s ability to contract and conduct nerve impulses.

Question 17

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

Accepted Answer

A protein-sugar mesh composed of ground substance and fibers

Question 18

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

Accepted Answer

Mast cells

Question 19

Which of the following best explains why cartilage injuries heal slowly in adults?

Accepted Answer

Cartilage is avascular and chondrocytes lose their ability to divide with age.

Question 20

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

Accepted Answer

$$	ext{Connective Tissue} = 	ext{Cells} + 	ext{Extracellular Matrix (Ground Substance + Fibers)}$$
