Q

What does cartilage allow the tissue to do?

A
  • withstand mechanical stress without permanent distortion
  • shock absorber ; sliding area for joints on articulating surface of bone (FACILITIES BONE MOVEMENT )
  • some bone forms from a previous cartilaginous pattern

Q

What is the surface of hyaline cartilage covered by?

A

Perichondrium

17
Q

What are clusters of chondrocytes referred to as?

A

Isogenous group

18
Q

Where is the surface of hyaline cartilage not covered by perichondrium ?

A

Articulate surface of joints

19
Q

How do cells o f hyaline cartilages get their nutrients ?

A

From the perichondrium

20
Q

What is the main difference between elastic and hyaline cartilage ?

A

The presence of elastic abundance fibres

21
Q

What is the most important functions of elastic cartilage ?

A

It can regain its shape after being distorted

22
Q

What surround the elastic cartilage ?

A

Perichondrium

23
Q

What is the collagen responsible in elastic cartilage ?

A

Type II collagen

24
Q

How can fibrocartilage be described ?

A

As an intermediate between dense irregular CT and hyaline cartilage

25
Q

How is fibrocartilage distinguished?

A

Arrangements if type I collagen fibres and the chondrocytes are arranged regularly

26
Q

What makes fibrocartilage different to elastic and hyaline cartilage ?

A

It does not contain perichondrium

27
Q

Why is the Lacuna smaller in fibrocartilage ?

A

The CT matrix itself is less intense (less solid)
