Question | Answer |
---|---|
bones fastened together by a thin layer of dense connetive tissue containing many collagenous fibera | Fibrous Joint |
-Bones bound by interosseous ligament -Joint Flexible and may be twisted | Syndesmosis Joint |
-Flat bones united by sutural ligament -No movement | Suture |
-Cone shaped process fastened in bony socket by periodontal ligament -No movement | Gomphosis |
Articulating bones connected by hyaline cartilage or fibrocartilage | Cartilaginous |
-Bones united by bands of hyaline cartilage -Movement ocurrs during growth process until ossification ocurrs | Synchondrosis |
-Articular surfaces seperated by thin layers of hyaline cartilage attached to band of fibrocartilage -Limited movement, as when back is bent or twisted | Symphysis |
Articulating bones surrounded by a joint capsule of ligaments and synovial membranes; ends of articulating bones covered by hyaline cartilage and seperated by synovial fluid | Synovial |
-Ball shaped head of one bone articulates with cup shaped socket of another -Movements in all planes; rotation | Ball and Socket |
-Oval shaped condyle of one bone articulates with elliptical cavity of another -Variety of movements in different planes, but no rotation | Condyloid |
-Articulating surfaces are nearly flat or slightly curved -Sliding or twisting | Gliding |
-Convex surface of one bone articulates with concave surface of another -Flexion and Extension | Hinge |
-Cylindrical surface of one bone articulates with ring of bone and fibrous tissue -Rotation | Pivot |
-Articulating surfaces have both concave and convex regions; surface of one bone fits the complementary surface of another -Variety of movements; mainly in two planes | Saddle |
