Question

which of the following articulations is not an example of a hinge joint?
ulna and humerus
atlas and axis
tibia and talus
femur and tibia
middle and distal phalanges

Explanation:

• Hinge joints allow movement in one plane (flexion - extension).
• The joint between the atlas (C1) and axis (C2) is a pivot joint, which allows rotational movement (e.g., shaking the head 'no').
• The ulna - humerus (elbow), tibia - talus (ankle in part of its movement), femur - tibia (knee), and middle - distal phalanges (interphalangeal joints of fingers/toes) are hinge - like in their primary movement patterns (flexion - extension).

Answer:

atlas and axis
