| Hinge joint | This joint allows movement in only one plane. |
| Pivot joint | Movement at this joint is limited to rotation about a central axis. |

| Synovial joint | A freely movable joint. |
| Synarthrosis | A joint in which the bones are fastened tightly together by a thin layer of fibrous connective tissue; an immovable joint. |

| Amphiarthrosis | A joint in which bones are connected by fibrocartilage or ligaments; a slightly movable joint. |
| Immovable joint | Occurs between bones that come in close contact with one another; separated by a thin layer of fibrous connective tissue or cartilage; no active movement takes place. |
| Joint | Functional junction between bones. |
| Suture | An immovable joint, such as that between adjacent flat bones of the skull. |

| Adduction | The movement of a body part toward the midline. |
| Pronation | A movement in which the palm of the hand is moved downward or backward. |
| Supination | Rotation of the forearm so that the palm faces the upward when the arm is outstretched. |
| Flexion | Bending a joint so that the angle between bones is decreased. |
| Extension | The movement by which the angle between the parts at a joint is increased. |
| Inversion | A movement in which the sole of the foot is turned inward. |
| Eversion | The movement in which the sole of the foot is turned outward. |
| Circumduction | The movement of a body part, such as a limb, so that the end follows a circular path. |
| Protraction | A forward movement of a body part. |
| Retraction | The movement of a part toward the back. |
| Elevation | Raising a body part, such as shrugging the shoulders. |
| Depression | Lowering a part of the body, such as drooping the shoulders. |
| Hyperextension | Excessive extension of the parts at a joint, beyond the anatomical position. |
| Ball and socket joint | This joint allows for a wider range of movement than any other joint. |
| Condyloid joint | This joint allows movement in different planes;rotational movement is not possible. |
| Gliding joint | This joint is found between some wrist and ankle bones, and allows sliding and twisting. |
