Question 3

Which connective tissue type is characterized by a matrix that is up to 80% water, lacks blood vessels, and contains chondrocytes in lacunae?

Accepted Answer

Cartilage

Question 4

Which of the following equations correctly represents the composition of the extracellular matrix in connective tissue?

Accepted Answer

$$Extracellular\ Matrix = Ground\ substance + Fibers$$

Question 5

A biopsy of a patient’s lymph node reveals a network of short, fine, highly branched fibers supporting white blood cells. Which fiber type is most abundant in this tissue?

Accepted Answer

Reticular fibers

Question 6

Which cell type is responsible for producing the matrix in bone connective tissue?

Accepted Answer

Osteoblasts

Question 7

A patient with a genetic defect in elastin production would most likely have issues with which connective tissue property?

Accepted Answer

Ability to stretch and recoil

Adipose tissue; adipocytes

Question 9

Which of the following best explains why cartilage heals more slowly than bone after injury?

A patient with scurvy (vitamin C deficiency) has weakened connective tissues. Which component is most directly affected?

Accepted Answer

Collagen synthesis

Question 15

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

Question 16

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

Accepted Answer

Elastic connective tissue

Question 17

Which cell type is primarily responsible for immune defense within reticular connective tissue?

Question 19

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

Accepted Answer
