3 Types of Cartilage
|
1 Hyalines2 Elastics3 Fibrocartilages
|
Hyaline Cartilage
|
Most abundant skeletal cartilages. Grant support w/ flexability and resiliance. Appears glassy when freshly exposed.
|
4 hyaline cartilages
|
1 articular2 costal3 respiratory4 nasal
|
Hyaline Cartilage Locations
|
1 articular- one the ends of most bones at movable joints. 2 costal- ribs and sternum. 3 respiratory- larynx (voicebox) and other respiratory -passages. 4 nasal- supports external nose.
|
Elastic Cartilage Locations
|
Ears and epiglotis
|
Perichondrium
|
Dense irregular connective tissue that surrounds the avascular cartilage
|
Appositional Growth
|
"growth from outside" cartilage forming cells in surrounding perichondrium secrete new matrix against external face of existing tissue
|
Interstitial Growth
|
"growth from inside" lacunae bound chondrocytes divide and secrete new matrix, expanding the cartilage from within
|
Two Classifications of Bone
|
Axial and appendicular
|
Axial Skeleton
|
Skull vertabral column and rib cage
|
Appendicular Skeleton
|
Limbs and the girdles (hips shoulder blade)
|
Mendibular cavity (yello marrow cavity)
|
Along center of longb bones
|
Trocanter
|
Only on femur
|
2 organic compounds of ground substance
|
Glycoprotiens protienglycans
|
Osteod seam
|
On outside of bone where osteo b lasts and clasts are
