Synovial joints
Types of joints
| Question | Answer |
|---|---|
| gliding joint (plane) | uniaxial movement They have flattened or slightly curved surfaces, and most glide slightly in only one axis. This is the simplest synovial joint. (permit slight movement) |
| What are examples of gliding joints? (plane) | the intercarpal and intertarsal joints of the wrist and foot |
| hinge joint (ginglymus) | uniaxial movement. A hinge joint permits only flexion and extention. Motion is simular to that of a door. |
| What are examples of hinge joints? (ginglymus) | elbow, knee and ankle |
| pivot joint (trochoid) | uniaxial movement. Only allows rotation around a single axis. |
| What are examples of pivot joints? (trochoid) | articulation of the atlas and axis of the cervical spine |
| ellipsoid joint (condyloid) | biaxial movement. Permits movement in two directions at right angles to each other. Flexion and extention occur along with abduction and adduction. Circumduction, a combo of both movements, can also occur. |
| What is an example of ellipsoid joints (condyloid) | radiocarpal joint |
| saddle joints (sellar) | biaxial movement. Permits movement in two axes, simular to the ellipsoid joint. |
| What is an example of the saddle joint? (sellar) | carpometacarpal joint |
| ball and socket joint (spheroid) | multi-axial movement. Permits movement in many axes: flexion and extention, abduction and adduction, circumduction, and rotation. |
| What are examples of ball and socket joints? (spheroid) | hip and shoulder |
