Joint Movements Flashcards
Define flexion
Bending parts at a joint so that
the angle between them decreases and the parts come closer together
(bending the knee)
Define extension
Straightening parts at a joint so that the angle between them increases and the parts move farther apart
(straightening the knee)
Define hyperextension
Extension of the parts at a joint beyond the anatomical position
(bending the head back beyond the upright position)
Define dorsiflexion
Movement at the ankle that brings the foot closer to the shin
(walking on heels)
Define plantar flexion
Movement at the ankle that brings the foot farther from the shin
(walking or standing on toes).
Define abduction
Moving a part away from the midline
(lifting the upper limb horizontally to form a right angle with the side of the body)
Define adduction
Moving a part toward the midline
(returning the upper limb from the horizontal position to the side of the body)
Define rotation
Moving a part around an axis
(twisting the head from side to side)
Define circumduction
Moving a part so that its end follows a circular path
(moving the finger in a circular motion without moving the hand)
Define supination
Turning the hand so the palm is upward or facing anteriorly
Define pronation
Turning the hand so the palm is downward or facing posteriorly
Define eversion
Turning the foot so the plantar surface faces laterally
Define inversion
Turning the foot so the plantar surface faces medially.
Define protraction
Moving a part forward
(thrusting the head forward)
Define retraction
Moving a part backward
(pulling the head backward)
