Types of Joint Mvmt

A&P CH7 Skeletal System Types of Joint Movement

flexion bending parts at a joint so that the angle between them decreases and the parts come closer together (bending the lower limb at the knee)
extension straightening parts at a joint so that the angle between them increases and the parts move farther apart (straightening the lower limb at the knee)
dorsiflexion bending the foot at the ankle toward the shin (bending the foot upward)
plantar flexion bending the foot at the ankle toward the sole (bending the foot downward)
hyperextension excess extension of the parts at a joint, beyond the anatomical position (bending the head back beyond the upright position)
abduction moving a pat away from the midline (lifting the upper limb horizontally to form a right angle with the side of the body
adduction moving a part toward the midline (returning the upper limb from the horizontal position to the side of the body
rotation moving a part around an axis (twisting the head from side to side)
circumduction moving a part so that its end follows a circular path (moving the finger in a circular motion without moving the hand)
pronation turning the hand so that the palm is downward or facing posteriorly (in anatomical position)
supination turning the hand so that the palm is upward or facing anteriorly (in anatomical position)
eversion turning the foot so that the sole faces laterally
inversion turning the foot so that the sole faces medially
retraction moving a part backward (pulling the chin backward)
protraction moving a part forward (thrusting the chin forward)
elevation raising a part (shrugging the shoulders)
