|
|
cartilage is :
(vascular / avascular) |
avascular
|
|
|
chondrocytes differentiated from
|
CT
|
|
|
Three types of cartilage?
|
hyaline
elastic fibrous |
|
|
What are the components of hyaline cartilage?
|
type II collagen
GAGs proteoglycans MAGs |
|
|
What is the perichondrium?
|
dense firmly attached CT between hyaline cartilage (surrounds) and GC, source of new chondrocytes
|
|
|
Which type of cartilage has the following characteristics:
- homogeneous, glassy and amorphous - chondrocytes exist alone or in isogenous groups - present in synovial joints - endochondral ossification |
hyaline cartilage
|
|
|
Water accounts for _________ of cartilage weight.
a) 90% b) 30% c) 40-60% d) 60-80% |
d
|
|
|
Which statement is false?
a) an isogenous group in hyaline cartilage is usually indicative of newly divided chondrocytes b) hyaline cartilage has 3 types of matrices: capsular, territorial and inter territorial c) stain well but with varying degrees (metachromasia) d) are uniformly distributed |
d
hyaline cartilage is not uniformly distributed |
|
|
perichondrium of non-articulating surfaces contributes to
|
joint capsule formation
|
|
|
which type of cartilage covers the surface of moving joints?
|
articular
|
|
|
Free and opposing surfaces of articular cartilage lack what?
|
perichondrium
|
|
|
What gives elastic cartilage its elastic properties?
|
elastin present in matrix
|
|
|
which type of cartilage has absolutely no perichondrium?
|
fibrocartilage
|
|
|
which type of cartilage has chondrocytes alone in columns or in isogenous groups?
|
fibrocartilage
|
|
|
what is chondrogenesis?
|
cartilage development
|
|
|
what are two types of cartilage growth?
|
appositional and interstitial
|
|
|
how does appositional growth create new cartilage?
|
forms new cartilage at the surface of existing cartilage
- derived from inner portion of perichondrium |
|
|
how does interstitial growth create new cartilage>?
|
forms new cartilage within existing cartilage

|
|
new cartilage by appositional growth is derived from ____________ whereas new cartilage by interstitial growth is derived from ___________.
|
inner portion of perichondrium
chondrocytes within lacunae |
|
|
if given enough time, opposing faces of_______ cartilage in contact with bone will eventually calcify and become bone
|
hyaline
|
