Joint Motions and Movements Quiz

Normal Joint Motions

• Flexion (flex): bending a joint
• Extension: straightening a joint
• Abduction (abd): movement away from the midline
• Adduction (add): movement towards the midline
• External Rotation (ER): outward rotation (lateral rotation)
• Internal Rotation (IR): inward rotation (medial rotation)

Special Kinds of Flexion and Extension

• Hyperextension: movement beyond the anatomical position, often used in reference to the knee or elbow

Special Kinds of Abduction and Adduction

• Shoulder horizontal abduction/adduction: movement of the arm across the midline
• Wrist radial deviation (RD): movement of the wrist towards the thumb side
• Wrist ulnar deviation (UD): movement of the wrist towards the little finger side
• Foot inversion (INV): movement of the foot inwards
• Foot eversion (EV): movement of the foot outwards
• Cervical Lateral Flexion (LF or SB): sidebending of the neck
• Trunk Lateral Flexion (LF or SB): sidebending of the trunk

Special Kinds of Rotation

• Forearm or forefoot supination (sup): rotating the forearm or foot upwards
• Forearm or forefoot pronation (pro): rotating the forearm or foot downwards
• Thumb opposition: thumb movement towards the other fingers
• Thumb reposition: returning the thumb to its original position
• Trunk rotation (R ROT and L ROT): rotation of the trunk

Other Motions

• Scapular or pelvic elevation/depression: raising or lowering the scapula or pelvis
• Scapular protraction (abduction) and retraction (adduction): scapular movement forward or backward
• Circumduction: circular movement of a limb
• Shoulder scaption: movement of the arm in a position between flexion and abduction
• Anterior pelvic tilt: tilting of the pelvis forward
• Posterior pelvic tilt: tilting of the pelvis backward
• Lateral pelvic tilt: tilting of the pelvis to the side

Test your knowledge on normal joint motions including flexion, extension, abduction, and adduction. This quiz covers special kinds of movements as well, such as hyperextension and wrist deviations. Perfect for students studying anatomy and biomechanics.
