16

What reinforces and strengthen ligaments in synovial joints?

reinforcing ligaments

17

What occupies the free space within a joint capsule, providing slippery, weight-bearing, film that reduces friction between cartilages?

synovial fluid

18

What are flattened fibrous sacs lined with synovial membrane and filled with synovial fluid located where ligaments, muscles, tendons, skin, and bone rub together?

bursae

19

What 3 main factors influence joint stability?

1. shape of articular surface

2. number and position of ligaments

3. muscle tone

20

What are ligaments?

a short band of tough, flexible, fibrous connective tissue that connects two bones or cartilages or holds together a joint
