Flexion Figure 9–3a
Flexion • Angular motion • Anterior–posterior plane • Reduces angle between elements
Extension • Angular motion • Anterior–posterior plane • Increases angle between elements
Hyperextension • Angular motion • Extension past anatomical position Angular Movements (Flexion, Extension, Hyperextension) PLAY
Abduction Figure 9–3b, c
Abduction • Angular motion • Frontal plane • Moves away from longitudinal axis
Adduction • Angular motion • Frontal plane • Moves toward longitudinal axis
Circumduction • Circular motion without rotation • Angular motion Figure 9–3d
Rotation Figure 9–4
Rotation • Direction of rotation from anatomical position • Relative to longitudinal axis of body
Rotation • Left or right rotation • Medial rotation (inward rotation): • rotates toward axis • Lateral rotation (outward rotation): • rotates away from axis
Pronation and Supination • Pronation: • rotates forearm, radius over ulna • Supination: • forearm in anatomical position
Inversion and Eversion Figure 9–5a
Inversion and Eversion • Inversion: • twists sole of foot medially • Eversion: • twists sole of foot laterally
Dorsiflexion and Plantar Flexion Figure 9–5b
Dorsiflexion and Plantar Flexion • Dorsiflexion: • flexion at ankle (lifting toes) • Plantar flexion: • extension at ankle (pointing toes)
Opposition • Thumb movement toward fingers or palm (grasping) Figure 9–5c
Protraction and Retraction Figure 9–5d
Protraction and Retraction • Protraction: • moves anteriorly • in the horizontal plane (pushing forward) • Retraction: • opposite of protraction • moving posteriorly (pulling back)
Elevation and Depression Figure 9–5e
Elevation and Depression • Elevation: • moves in superior direction (up) • Depression: • moves in inferior direction (down)
Lateral Flexion • Bends vertebral column from side to side Figure 9–5f
