A

Lacunae

25
Q

Which are the weakest type of cartilage

A

Hyaline

26
Q

Hyaline cartilage repair very fast? True or false

A

False super slow because no blood vessels or nerves

27
Q

What is the role of hyaline cartilage

A

Flexibility support resilient and shock absorbing

28
Q

Where do we find hyaline cartilage

A

Articular surface of long bones so:
Nose
Larynx trachea
Bronchi bronchioles
Central ends of ribs
Skeleton of the embryo

29

Do we have perichondrium is elastic cartilage yes or no

A

Yes

33
Q

Where do we have elastic cartilage ?

A

Eustachian tube
Ear
Vocal cartilage

34
Q

What is the function of elastic cartilage

A

Support and form elastic

35
Q

Which type of cartilage permit the maintain of shape of organs after deformation ?

A

Elastic cartilage

36
Q

What is the function of fibrocartilage

A

Provide strength

37
Q

A

Fibrocartilage

38
Q

Where do we find fibrocartilage

A

Intervertebral disc
Meniscus
Temporomandibular joint

39
Q

Did fibrocartilage had perichondrium

A

No

40
Q

Fibrocartilage don’t have lot of layers yes or no?

A

No fibrocartilage has multiple organized layers of collagen

41
Q

How can we recognize fibrocartilage ?

A

Thank to hematoxylin and eosin stain

42
Q

What is chondrogenesis

A

The process of cartilage development begin when chondroprogenitor mesenchymal cells cluster together to form a dense mass of rounded cells

43
Q

Where cartilage originates?

A

From the mesenchyme during chondrogenesis

44
Q

Repair and growth of cartilage is a fast process true or false
