Articulations
A Classification of Joints
Articulations
Articulations
Where two bones interconnect
Immovable joints
Synarthroses, or bony
Slightly moveable joints
Amphiarthroses, or fibrous / cartilagenous
Freely moveable joints
Diarthroses, or synovial
Synarthroses (immovable joints)
Four major types
Suture = skull bones bound together by dense connective tissue
Gomphosis = teeth bound to bony sockets by periodontal ligaments
Synchondrosis = two bones bound by rigid cartilaginous bridge
Syntosis = two bones completely fused
Amphiarthroses (slightly movable joints)
Two major types
Syndesmosis = bones connected by a ligament
Symphysis = bone separated by fibrocartilage
Diarthroses (freely movable joints)
Bony surfaces enclosed within articular capsule
Bony surfaces covered by articular cartilage
Bony surfaces lubricated by synovial fluid
Structures include
Menisci
Fat pads
Accessory ligaments
Bursae
