Articulations

loading
Ball and socket joint
allow angular movement in all directions. Such as shoulder and hip joints.
Pivot joint
allow rotation mov. around a pivot point, such as atlas around the odontoid process of the axis.
Saddle joint
occer where end of both bones are saddle-shaped, convex in one direction and concave in the other. thumb and trapezium
Condyloid joints
allow movement in two planes. Formed by rounded condyle articulating with an elliptical depression, such as btw, carpus and the radius.
Hinge joint
allow movement in only one plane. ex: elbow and knee
Gliding joint
occur btw. small bones w flat of slightly convex surfaces,such as the carpal and tarsal bones.
Diarthrotic joints
gliding,hings,cibdykoid,saddle,pivot, ball and socket.
Diarthrotic joint characteristic
synovial fluid that lubricates joint.
Diarthrotic
freely movable. joints bound by a fibrous articular capsule formed of ligaments.
Syndesmoses
lack firbocartliage, but the bones are held together by fibrous connective tissue forming interosseous ligaments.
Symphyses
The joint is wrapped in a fibrous capsule formed of ligaments
Symphyses
have cushioning pad of fibrocartliage between the bones. adjacent to the cartilagenous pads, the articular surfaces of the bones are cover with articular cartliages that reduce friction.
Amphiarthrotic Joints
Symphyses,syndesmoses
Amphiarthrotic
slightly movable bound by fibrous tissue or cartliage.
Synchondroses
have cartliage as the bonding tissue. ex: epiphysis to diaphysis through the epiphyseal cartliages.
Sutures
irregular joints btw. the immovable bones of the skull. Bonded by fibrous connective tissue that is continuous with the periosteum on the outer surface of the bones w duramater on the inner surface of the bones.
synathrotic
immovable. Bones tightly bonded by fibrous connective tissue or cartilage.
synarthrotic joints,
sutures,synchondrose.
