Transcript of Classifications of Synovial Joints

SYNOVIAL JOINTS
Classification of Synovial Joints
By: Alejandra, Diana, Gabriela, & Melvin

HINGE JOINT
Permits angular movement in a single plane.
Movement: monaxial
Examples:
Elbow joint
Knee joint
Ankle joint
Interphalangeal joint

PIVOT JOINT
Are monaxial however allow rotation
Consist of rounded bone of one end fitting into a ring formed by another
Example:
Joint of first and second neck vertebrae
Joint of the wrist
Atlanto-axial joint

CONDYLAR JOINT
Also called Ellipsoid joint
An oval articular face nestles within a depression in the opposing surface.
All angular movements occur around two axes.
Movement: biaxial
Allows for flexion, extension, abduction, and adduction
Examples:
Radiocarpal joint
Metacarpophalangeal points 2-5
Metatarsophalangeal joints

SADDLE JOINT
Allows angular movement and Circumduction
Prevents rotation
Joint where one of the bones form a saddle shape and another bone rests on it
Provide more stability and flexibility more than a gliding or hinge joint
Movement: Biaxial
Example:
First carpometacarpal joint
BALL-AND-SOCKET JOINT
-The round head of one bone rests within a cup shaped depression in another
-Triaxial- joints that allow a combination of rotation and angular movement
-All angular and rotational movements, like circumduction, can be done at ball-and-socket joints
-Examples:
Shoulder joint
hip joint
GLIDING JOINTS
Also called plane joints
Has flattened or curved faces
The flat surfaces slide across each other, but in a slight amount of movement
Rotation can be theoretically possible, but the ligaments try to prevent rotation
Movement: Slight multiaxial
Ex:ample
Acromioclavicular and claviculosternal joints
Intercarpal and intertarsal joints
Vertebrocostal joints
Sacro-iliac joints
