3 Joint Classifications
1) Fixed (fibrous)
2) Slightly movable (cartilagenous)
3) Freely moveable (synovial)
Fixed Joints
no movement
Connects bone w/ tough fibre
eg. Ilium + pubis, parietal + frontal
Slightly moveable (cartilagenous)
slight movement
+2 bones connected via cartilage
eg. vertebrae, ribs/sternum, pubis symphasis
Freely moveable (synovial)
large range of motion
joint capsule
