Histo-Cartilage Flashcards
Chondroblasts are derived from these type of cells
Mesenchymal stem cells
Extracellular matrix is composed of
Protein fibers and ground substance
Type of cells that secrete extracellular matrix
Chondroblasts
Where are chondroblasts found
Edge of new cartilage
Adult form of cartilage cells
Chondrocytes
Extracellular matrix is rich in these 2 substances
Glycosaminoglycans and proteoglycans
The ability of extracellular matrix to withstand mechanical forces is due to this
Water
This surrounds most cartilage
Perichondrium
What type of tissue is found in perichondrium
Dense connective tissue
Where is perichondrium found
Muscles, nerves, fibroblasts
What type of cartilage is found in perichondrium
Type I
What is the role of perichondrium
Growth and maintenance of cartilage
T/F Cartilage is vascular
False. It is avascular
The growth of cartilage by addition to an existing surface
Apposistional growth
Apposistional growth generates new________.
Chondroblasts
Growth of cartilage by internal expansion
Interstitial growth
Interstitial growth involves the proliferation of________.
Chondrocytes
The formation of isogenous groups is found in this type of cartilage growth
Interstitial
Hyaline cartilage has this type of collagen
Type II
Where is hyaline cartilage found that does not have perichondrium
Articular surfaces
What do chondrocytes sit in
Lacunae
A group of chondrocytes sitting in individual lacunae is called this
Isogenous groups
The apperance of isogenous groups tell you the cell is going through this
Mitosis
This is found around isogenous groups. It is identifiable by its more basophilic apperance
Territorial matrix
