Avascular and aneural
Matrix of fibers (always containing type II collagen) and ground substance
What are the key characteristics of cartilage?
GAGs such as hyaluronic acid, proteoglycans, and glycoproteins
What makes up the ground substance of cartilage?
Hyaline cartilage, elastic cartilage, and fibrocartilage
What are the types of cartilage?
Forms the primary skeleton and serves as model for endochondral bone
formation
What does hyaline cartilage do in the fetus?
Hyaline cartilage
Identify the region labeled A
,Dense Regular CT
Identify the region labeled B
Developing bone
Identify the region labeled C
Growth by adding ECM/cells to the surface layer
What is appositional growth?
DRCT surrounding cartilage (not in fibrocartilage or articular cartilage or the
epiphyseal growth plate)
What is the perichondrium?
glassy
What does hyaline mean?
Recently divided chondrocytes that sit in clusters
What are isogenous groups?
,Type II collagen
What fibers are present in hyaline cartilage?
Yes, typically
Are isogenous groups visible in hyaline cartilage?
Perichondrium usually present
Chondroblasts near perichondrium if present
Chondrocytes in lacunae (medium sized)
Territorial matrix visible
Isogenic groups present/visible
What are the key histological features of hyaline cartilage?
Resists compressive forces
Provides flexible support in the respiratory system
Provides resilience with low friction on articular surface
What is the function of hyaline cartilage?
Tracheal rings, some laryngeal cartilage, nasal septal cartilage, costal cartilage
, Articular joint surface of diathrodial
Epiphyseal growth plate
Where would you find hyaline cartilage?
Small white-appearing area that surrounds chondrocytes
What are lacunae?
Isogenous group
What is a cluster of chondrocytes called?
territorial or capsular matrix
The edge of lacunae typically has a more basophilic stain - what is this called?
inter-territorial matrix
What is the lighter stained area between lacunae?
Perichondrium
