Skeletal Cartilage

Question 0

Cartilage is mostly made up of what …?

Answer 0

Water

Accounts for its resilience.

Question 1

Made of some variety of cartilage tissue, which is molded to fit its body location and function.

Answer 1

Skeletal tissue

Question 2

“Around the cartilage”

Answer 2

Perichondrium

Question 3

What is the function of the Perichondrium ?

Answer 3

Acts as a girdle to resist outward expansion when cartilage is compressed.

Also contains blood vessels from which nutrients diffuse through matrix to reach cartilage cells internally.

Limits thickness

Question 4

Layer of Dense irregular connective tissue which surrounds cartilage

Answer 4

Perichondrium

Question 5

Name 3 types of cartilage in the body

Answer 5

Hyaline cartilage
Elastic cartilage
Fibrocartilage

Question 6

What are the basic components of cartilage?

Answer 6

1. ) chondrocytes
2. ) encased in lacunae within extracellular matrix containing ground substance
3. ) fibers

Question 7

Type of cartilage that looks like frosted glass when freshly exposed.

Answer 7

Hyaline cartilage

Question 8

What is the function of hyaline cartilage?

Answer 8

Provides support with flexibility and resilience.

Question 9

Which type of cartilage is the most abundant?

Answer 9

Hyaline cartilage

Question 10

What are the characteristics of hyaline cartilage?

Answer 10

Chondrocytes are spherical

Only fiber in matrix is fine collagen fiber

Question 11

List the types of hyaline cartilages

Answer 11

Articular
Costal
Respiratory
Nasal

Question 12

Where would articular cartilages be found?

Answer 12

Covering the ends of most bones at movable joints

Question 13

Where would costal cartilage be found?

Answer 13

Connecting ribs to sternum

Question 14

Where would respiratory cartilage be found?

Answer 14

Forms skeleton of the larynx and reinforces other respiratory passageways

Question 15

Where would nasal cartilage be found?

Answer 15

Supporting external nose

Question 16

Type of cartilage that resembles hyaline cartilage, but can stand up to repeated bending.

Answer 16

Elastic cartilage

Question 17

What allows elastic cartilage to be more flexible than hyaline cartilage ?

Answer 17

Elastic fibers

Question 18

Found in external ear and epiglottis.

Answer 18

Elastic cartilage.

Question 19

Type of cartilage that is highly compressible with treat tensile strength.
Consists of two rows of parallel chondrocytes alternating with thick collagen fibers.

Answer 19

Fibrocartilage

Question 20

Found in meniscus of the knee and discs between vertebrae.

Answer 20

Fibrocartilage

Question 21

Two ways cartilage grows?

Answer 21

Appositional growth

Interstitial growth

Question 22

Define apposition all growth

Answer 22

Growth from outside.

Cartilage-forming cells in Perichondrium secrete new matrix against external face of the existing cartilage tissue.

Question 23

Define interstitial growth

Answer 23

Growth from inside.

The lacunae-bound chondrocytes divide and secrete new matrix, expanding the cartilage within.

Question 24

When does cartilage growth typically end?

Answer 24

During adolescence, when the skeleton stops growing.
