Q

Flexion

A

-a movement that decreases the angle of a joint
— muscle pushes up, doesn’t pull
ex;squating ( starting as standing then to bending the knee)

36
Q

Extension

A
  • a movement that increases the angle of joint
  • part limbs move backward
  • Ex; starting as bending the knee to standing up

Q

Abduction

A

movement of a body part laterally away from midline

  • moves on the side
  • EX; moving the legs sideway
  • Ex using the weights, moving arms sideways
38
Q

Adduction

A

movement of a body part medially toward midline

  • move medial
  • Ex; leg work, moving the legs sideways
39

Q

Medial (Internal ) Rotation

A
  • turn anterior aspect of limb toward midline
42
Q

Lateral ( External)

A
  • turns anterior aspect of limb from midline of body
43
Q

Circumduction
