Chapter 7: Cartilage

++
++
++

The molecular basis for the shock absorbing properties of cartilage involves which of the following?

++
++
++

a. Electrostatic interaction of proteoglycans with type IV collagen

++
++

b. Ability of glycosaminoglycans to bind anions

++
++

c. Noncovalent binding of glycosaminoglycans to protein cores

++
++

d. Sialic acid residues in the glycoproteins

++
++

e. Hydration of glycosaminoglycans

++
++
++

What distinguishes cartilage from most other connective tissues?

++
++
++

a. Its extracellular matrix is rich in collagen.

++
++

b. Its predominant cell type is a mesenchymal derivative.

++
++

c. Its predominant cell type secretes both fibers and proteoglycans.

++
++

d. It lacks blood vessels.

++
++

e. It functions in mechanical support.

++
++
++

Which feature is typical of elastic cartilage?

++
++
++

a. Primary skeletal tissue in the fetus

++
++

b. No identifiable perichondrium

++
++

c. Found in intervertebral discs

++
++

d. Most widely distributed cartilage type in the body

++
++

e. Collagen is mainly type II

++
++
++

Which area in cartilage is relatively collagen-poor and proteoglycan-rich?

++
++
++

a. Fibrocartilage

++
++

b. Territorial matrix

++
++

c. Epiphyseal plate

++
++

d. Interterritorial matrix

++
++

e. Perichondrium

++
++
++

What is the source of the mesenchymal progenitor cells activated for the repair of hyaline cartilage of accident-damaged costal cartilages?

++
++
++

a. Perichondrium

++
++

b. Adjacent loose connective tissue

++
++

c. Bone of the adjacent rib(s) and sternum

++
++

d. Chondrocytes of the injured cartilage

++
++

e. Stem cells circulating with blood

++
++
++

How does articular cartilage differ from most other hyaline cartilage?

++
++
++

a. It undergoes mainly appositional growth.

++
++

b. It contains isogenous groups of chondrocytes.

++
++

c. It lacks a perichondrium.

++
++

d. Its matrix contains aggrecan.

++
++

e. It is derived from ...
