A
- Facilitate growth
- Transmit forces
- Allow movement
2
Q
Why do younger ppl have more joints
A
- Epiphyseal plate hasn’t fused, so more cartilage
3

- Cartilaginous
- Synovial
12
Q
Features of a synovial joint x4
A
- Fibrous capsule
- Synovial membrane
- Articular cartilage
- Articular cavity/capsule
13
Q
Fibrous capsule
- structure
- function x2
A
- Collagen fibres, rich nerve supply
- Gives structure, holds bones together
14
Q
Fibrous capsule & ligaments….
A
Fibrous capsule can thicken along lines of stress –> ligaments
15
Q
Why is nerve supply important in the fibrous capsule
A
Important for proprioception
body’s awareness of its position in space
