CHAPTER 7: CARTILAGE

Question 1

a tough, durable form of supporting connective
tissue

Answer 1

Cartilage

Question 2

characterized by an extracellular matrix (ECM) with
high concentrations of GAGs and proteoglycans,
interacting with collagen and elastic fibers.

Answer 2

Cartilage

Question 3

consists of cells called chondrocytes embedded in
the ECM

Answer 3

Cartilage

Question 4

physical properties depends on electrostatic bonds
between type II collagen fibrils, hyaluronan, and the
sulfated GAGs on densely packed proteoglycans

Answer 4

Cartilage

Question 5

lack vascular supplies and chondrocytes receive
nutrients by diffusion from capillaries in surrounding
connective tissue

Answer 5

Cartilage

Question 6

o Lacks nerves

Answer 6

Cartilage

Question 9

located in matrix cavities

Answer 9

Chondrocytes

Question 10

exhibit low metabolic activit

Answer 10

Lacunae

Question 11

Young chondrocytes are called _________ which
have an elliptic shape, with the long axes parallel to
the surface

Answer 11

chondroblast

Question 12

• chondrocyte found deeper
  in cartilage and appear in groups

Answer 12

Isogenous Aggregates-

Question 13

a sheath of dense connective tissue that surrounds
cartilage in most place

Answer 13

Perichondrium

Question 14

forms an interface between the cartilage and the
tissues supported by the cartilage.

Question 15

harbors the blood supply serving the cartilage

Question 16

covers all hyaline cartilage except in articular
cartilage of joints

Question 17

essential for the growth and maintenance of
cartilage

Question 18

The outer region of the perichondrium consists
largely of _______ and fibroblasts
o inner layer adjoining the cartilage matrix also
contains ____________

Answer 18

collagen type I fibers

mesenchymal stem cells

Question 19

avascular,
o Where the dry weight of hyaline cartilage is
embedded

Question 20

generally basophilic and the thin collagen fibrils are
barely discernible.
o Composed of chondronectin a structural
multiadhesive glycoprotein which binds specifically
to GAGs, collagen, and integrins, mediating the
adherence of chondrocytes to the ECM.

Answer 20

Matrix
