Flexion
(Extension)
Decrease in the angle between bones forming the joint
Extension
(Flexion)
Increase in the angle between bones forming the joint
Hyperextension
Movement that exaggerates extension at a joint
Dorsiflexion
(Plantar flexion)
Flexion of the foot at the ankle
Plantar flexion
(dorsiflexion)
Extension of the foot at the ankle
Abduction
(adduction)
Movement of a bone away from the midline
Adduction
(abduction)
Movement of a bone towards the midline
Rotation
Movement of a bone around its longitudinal axis
Medial rotation
Rotation of a limb so its anterior surface turns medially
Lateral rotation
Rotation of a limb so its anterior surface turns laterally
Circumduction
Movement of the distal end of a bone in a circle while proximal ends form the pivot joint
Eversion
Movement of the sole of the foot laterally
Inversion
Movement of the sole of the foot medially
Pronation
Rotation of the forearm when the palm is turned inferiorly or posteriorly
Supination
Rotation of the forearm when the palm is turned superiorly or anteriorly
Protraction
Movement of a body part anteriorly
Retraction
Movement of a body part posteriorly
Elevation
Movement of a body part superiorly
Depression

Opposition
Movement of the thumb to touch the other four fingers
Reposition
Movement of the thumb back to the anatomical position
Anterior (or ventral)
Front (the kneecap is located on the anterior side of the leg)
Posterior (or dorsal)
Back (the shoulder blades are located on the posterior side of the body)
Inferior (or caudal)
Away from the head; lower (the food is part of the inferior extremity)
Medial
Towards the midline of the body (the big toe is located at the medial side of the foot)
Lateral
Away from the midline of the body (the little toe is located at the lateral side of the foot)
Proximal
Toward or nearest the trunk of the point of origin of a part (the proximal end of the femur joins with the pelvic bone)
Distal
Away from or farthest from the trunk or the point of origin of a part (the hand is located at the distal end of the forearm)
Coronal plane (frontal plane)
A vertical plane running from side to side; divides the body or any of its parts into anterior or posterior portions
Sagittal plante (lateral plane)
A vertical plane running from front to back’ divides the body of any of its parts into right and left sides
Axial plane (transverse plane)
A horizontal plane; divides the body or any of its parts into upper and lower parts
Median plan
Saggital plane through the midline of the body; divides the body or any of its parts into right and left halves
