human CT & joints depend on _______ to assume final form?
|
function
|
|
|
FUnction of a joint is dependant on ?
|
structure (design)
Composition (materials |
|
|
mobility of a joint is inversely related to joint stability
|
more movement= less stability
more stability= less movement |
|
|
Wolffs Law is?
|
Every change in function of a bone is followed by certain definite changes in its internal architecture and external conformation
|
|
|
CT proper
|
varies in density & elasticity
|
|
|
Cartilage, what are three types?
|
hyaline
elastic fibrocartilage |
|
|
Bone, what are two types
|
compact (cortical)
spongy (cancellous), Hardest CT due to inorganic hydroxyapatite |
|
|
Blood
|
fluid with cellular components
|
|
|
Collagen
|
1most abundant protein in body
2.main substance of CT 3.referred to as GLUE of body 4.tremendous tensile strength 5. 25-30% of all protein found in mammals |
|
|
`Ligaments
|
bone to bone
2. few cells with much extra cellular material, mostly collagen w/ some elastic |
|
|
Tendons
|
connect muscle to bone
similar composition as ligaments |
|
|
Bursae
|
sacs of synovial membrane containing synovial fluid
-reduces friction between structures |
|
|
Fibrocartilage
|
1. white
2. tough, limited mobility in joints w/ limited motion IVDs |
|
|
Hyaline
|
1. articular
tough, very smooth, -occurs at end of bones -greatly reduces friction |
|
|
Elastic
|
1. yellow
aka-elastin 2. flexible, resilient ear, nose and skin |
