| Description | Structure |
| Dense fibrous tissue (cords) that lashes bones firmly together. | |
| Reduces shock and increases lubricated surface contact arm (in case of a poor bone fit). | |
| Small space between the articulating bones that is filled with synovial fluid and allows the bones to articulate freely. | |
| Small fluid filled sac, found between moving structures (tendon and bone) to facilitate friction-free movement. | |
| Covers and cushions the ends of articulating bones. | |
| Sleevelike extension of the periosteum of each articulating bone. Encases the joint and helps to bind the bones together. | |
| Moist and slippery, lines inner surface of the joint capsule. Secretes synovial fluid which lubricates the joint. | |
