A
- calcium -other elements
5
Q
Joint capsule

Joint capsule layers
A
Fibrous membrane
Synovial membrane
7
Q

A
the outer layer which is thick and tough and hold the joint together
8
Q
Synovial membrane
A
the inner layer which secretes the synovial fluid
9
Q
Cartilage
A
lies on the ends of the bones to absorb shock
- its smoothness prevents friction
10
Q

A
- lubricates joints
- prevents wear of cartilage
- allows smooth movement of the joint
- transports nutrients to the cartilage
11
Q
Ligaments
A
tough fiberous bands that connect bones to bones
- especially needed for joints
12
Q
Changes to joints
A
- worn/thin cartilage
- thin synovial fluid - decreases ability of joint to slide freely
- torn.damaged ligaments - fail to supprot the joint
13
Q
Cause of Infectious Arthritis
A
- bacteria enter the body and travel through the bloodstream to the joint, or driectly to the joint by trauma
- bacterial infect the synovial fluid
14
