Joint Types
Synarthroses- Joints the don't move
Amphiarthroses- Slightly moveable joints connected by fiberous cartilage
Dairthroses- (synovial joints)- Freely movable joints, held together by ligaments
1. Ball and socket joint- Ball shaped head of one bone fits into depression (socket) of another bone, they can move in all planes(circular movements, and rotation) ex. hip, and shoulder
2. Condyloid joint- Oval shaped condyle fits in ival shaped cavity of another bone, can move in different planes but not rotate. ex. Wrist joints between radius and carpals.
3. Gliding joints- (sternoclavicular joints) Flat or slightly curved surfaces join, move by sliding or twisting. ex. between carpal and tarsal bones
4. Hinge joints- Convex surface with concave surface, Moves in an up and down motion. ex. elbow and knee
5. Pivot Joint- Shaped projection on one bone is surrounded by a ring of another bone and ligament, Movement is only rotation. ex. joint of radius and ulna, or top of the vertebral column.
6. Saddle Joint- 2 saddle shaped bones fit together, Creates many movements except rotation. Ex. 1st carpal and 1st metacarpal bone of thumb.
