Joints can be classed by how they attach two bones (structure) and the way they allow two bones to move (function). How does the joint hold two bones together? Synovial: joint cavity with synovial fluid Fibrous: no cavity and collagenous adhesive Cartilaginous: no cavity and cartilagenous adhesive How do the two bones move across a joint? Diathroses: freely moving Amphiarthroses: Slightly moveable Synarthroses: Little or no movement Note: there is a lot of crossover between these “classes” of joint.
