7
Q
describe fibrous jts
A
- bone united by fibrous tissue
- nonsynovial
- minimal to no movement
8
Q
describe cartilaginous jts
A
- hyaline cartilage or fibrocartilage connects one bone to another
- slightly moveable
9
Q
describe synovial jts
A
- free movement between bones
- most complex and vulnerable to injury
- classified by type of movement and shape of articulating bones
10

A
- joint cavity
- articular cartilage
- synovial membrane
- synovial fluid
- fibrous capsule
11

eventual fusion of suture is called
A
synostosis
12
Q
What is a suture?
A
union of two bones by a ligament or membrane
13
Q
What is a syndesmosis?
A
- bone connected to bone by dense fibrous membrane
- very little motion
*interosseous membrane (tib/fib)
14
Q
What is a gomphosis?
A
- peg in hole
- tooth in socket
15
