Question 1

Which of the following statements best describes the role of cartilage in the skeletal system?

Accepted Answer

Cartilage is a semi-rigid connective tissue that provides flexibility, supports soft tissues, and serves as a precursor model for bone growth.

Question 2

Which cell type is responsible for producing the extracellular matrix in cartilage before becoming surrounded by it?

Accepted Answer

Chondroblasts

Question 3

What is the significance of lacunae in cartilage tissue?

Accepted Answer

Lacunae are small spaces within the matrix that house chondrocytes.

Question 4

Which type of cartilage is most abundant in the human body and is found in the respiratory tree, joints, and fetal skeleton?

Accepted Answer

Hyaline cartilage

Question 5

A patient presents with a torn meniscus in the knee. Which type of cartilage is most likely involved in this injury?

Accepted Answer

Fibrocartilage

Question 6

Which of the following is a function of cartilage at articulations (joints)?

Accepted Answer

It provides smooth gliding surfaces where bones appose each other.

Question 7

Which type of cartilage is found in the auricle of the ear and the epiglottis, and is characterized by highly branched elastic fibers?

Accepted Answer

Elastic cartilage

Question 8

Why is mature cartilage considered avascular, and what is a clinical implication of this property?

Accepted Answer

It lacks blood vessels, so nutrients must diffuse through the matrix, resulting in slow healing after injury.

Question 9

Which of the following best explains why cartilage is more flexible and resilient than bone?

Accepted Answer

Cartilage has a semi-rigid matrix with fewer mineral deposits and more water content.

Question 10

A forensic anthropologist is examining a skeleton to estimate age. Which cartilage-related feature would be most useful for determining if the individual was a juvenile?

Accepted Answer

Presence of unfused epiphyseal plates composed of hyaline cartilage

Question 11

Which of the following equations best represents the chemical composition of the mineral component found in bone, but NOT in cartilage?

Accepted Answer

$$Ca_5$$($$PO_4)_3OH$

Question 12

Which of the following is NOT a function of cartilage?

Accepted Answer

Storage of calcium and phosphate

Question 13

Which type of cartilage is most likely to be found in regions of the body that require both strength and the ability to absorb shock, such as the pubic symphysis?

Accepted Answer

Fibrocartilage

Question 14

Which of the following statements about chondrocytes is correct?

Accepted Answer

Chondrocytes are mature cartilage cells that reside in lacunae and maintain the cartilage matrix.

Question 15

Which type of cartilage is NOT surrounded by perichondrium?

Accepted Answer

Fibrocartilage

Question 16

Which of the following best describes the distribution of hyaline cartilage in the body?

Accepted Answer

It is found in the respiratory tree, joints of bones, and fetal skeleton.
