| In structural classification, synovial movement is? | Freely movable |
| In structural classification, fibrous movement is? | Immovable |
| In structural classification,cartilaginous movement is? | Limited or slight movement |
| The type of movement(s) in a gliding (plane) joint | Sliding & gliding |
| The type of movement(s) in a hinge (ginglymus) joint | Flexion & extension |
| The type of movement(s) in a pivot (trochoid) joint | Rotation around single axis |
