Bone
Orients along lines of stress. Bears weight, and help bones resist bending and twisting
What is Trabeculae?
the ability to resist breakage and permanent deformation
What is a strength?
meeting point, where two or more bones meet
What are the joints/articulations?
motion on only 2 axis
What is biaxial?
constant build-up and breakdown of the boney matrix in direct relation to the forces acting on them
What is bone remodeling?
Double layered connective tissue covering the outer surface of bone except where articular cartilage is present
What is Periosteum?
two molecules of bone driven into one another. 1330-2100 kg/cm2
What is compression?
It starts in an embryo at about 8 weeks becomes flat sheets of bone, stops at about 2 years of age.
What is Intramembranous ossification?
non-swelling(inflammatory) joint inflammation
What is osteoarthritis?
Inflammatory joint inflammation(swelling)
What is Rheumatoid arthritis?
The ability to return to the original shape after the load is removed
What is elasticity?
the deformation of an object due to stress
What is the strain?
Insufficient amounts of vitamin D in children result in bowed bones and inflamed joints.
What is rickets?
Non-Moving joints
What is Synarthrosis?
moves only on one axis
What is uniaxial?
A layer of bone that is cellular only
What is endosteum?
Two molecules of bone being pulled directly away from one another.
620-1050 kg/cm2
What is tension?
It begins with the formation of a cartilage model. Starts at about 8 weeks inutero and continues until death.
What is Endochondral ossification?
Free moving joint
What is Diarthrosis?
Joint capsule with a synovial membrane/synovial fluid, a joint cavity filled with synovial fluid, articular cartilage.
**synovial membrane makes synovial fluid.
What is a synovial joint?
1/3 of living bone is made up of this
What is collagen?
Two molecules are driven directly oast one another in opposite directions.
500 kg/cm2 ll
1000 kg/cm2 _l_
What is Shear?
Vitamin C deficiencies in both adults and children that leads to ulceration and hemorrhage in almost any area of the body because normal collagen synthesis is not occurring in connective tissues
What is Scurvy?
slightly moving joint
What is amphiarthrosis?
a motion on more than 2 axis
What is multiaxial?
