Answer
The two basic characteristics used in classifying joints are:
1. The manner in which the adjacent bones are joined to each other ( one another).
For examples there are bony joints ( bone joined to bone); cartilaginous joints ( bones joined by
hyaline cartilage ) and bones joined by collagen fibres or fibrocartlage.
Work Step by Step
2. How freely the bones in the joints can move.
Ball and socket joints ( shoulder joint) are the most freely movable joints..
Hinge joints ( elbow and knee) allow flexion and extension
Plane joints of the wrist ( carpals) allow only gliding movements.
Suture joints allow no movements at all.
