Cartilage is what? |
a firm nonmineralized connective tissue serves as a skeletal tissue in the body |
|
|
Cartilage forms much of the temporary skeleton on the what? |
Embryo |
|
|
Connective tissue surrounding most cartilage is what? |
Perichondrium |
|
|
what is cartilage composed of? |
Cells and Matrix |
|
|
The cartilage matrix is mainly made up of what? |
fibers, mainly collegen, and intercellular substance |
|
|
There are two types of cells that lie in cartilage what are they? |
Chrondrablast Chondrocytes |
|
|
Chrondroblast are what? |
lie internal to the perichondrium and produce cartilage matrix |
|
|
Chondrocytes are what? |
Mature chrondroblast that maintain the cartiliage matrix |
|
|
After production of the cartilage matrix what happens? |
The chondrocyte becomes surrounded and enclosed by the matrix |
|
|
Whats the small space that surrounds the chrondocyte within the cartilage matrix? |
Lucuna |
|
|
There are three types of cartilage what are they? |
Hyaline, Elastic, and fribrocartilage |
|
|
What is the most common type of cartilage in the body? |
Hyaline |
|
|
Where is Hyaline found? |
Embryonic skeleton and growth centers such as the mandibular condyle |
|
|
What does all cartilage start as? |
Hyaline Cartilage |
|
|
The Elastic Cartilage is similar to what? |
Hyaline cartilage |
|
|
Elastic Cartilage has what? |
Numerous collagen and elastic fibers |
|
|
What is Fibrocartilage? |
Is never found alone merges with hyaline cartilage |
|
|
unlike the hyaline cartilage and elastic cartilage fibrocartilage is has no what? |
no perichondrium overlying it |
|
|
Cartilage can grow in two ways what are they? |
Interstitial growth appositional growth |
|
|
What is interstitial growth? |
From within the tissue by the mitosis of each chondrocyte
producing large numbers of daughter cells within a single Lunca |
|
|
What is appositional growth? |
layered growth on the outside of the tissue from an outer layer of chondroblasts within perichondrium |
|
|
What is always present on the external surface of cartilage to allow apposistional growth of cartilage after injury |
That layer of chrondroblast |
|
|
Repair and aging of Cartilage |
............... |
|
|
What are 4 specific things to remember about cartilage |
Has flexibility from its fibers Avasucular takes longer to repair Has no nerve supply |
|
|
Repair of the avascular cartilage is dependant on what? |
Connective tissue from the Perichrondrium for nutrition |
|
|
As Cartilage ages is beomes what? |
Less flexible and less cellular |
