Movements of Synovial Joints

Lateral (external) rotation
if you stand with bent elbow and reach out with your right arm to grasp something on the right side of your body, your humerus does this motion
abduction of thumb
move thumb away from the plane of the hand so it points anteriorly
zero position
anatomical position
a movement that decreases a joint angle
extreme extension of a joint, beyond the zero position
lowers a body part in the frontal plane
posterior movement of a body part in the transverse plane
a movement in which a bone spins on its longitudinal axis
causing the palm to face posteriorly (downward) and radius to cross the ulna like an X
radial flexion
tilt hand toward thumb
a movement in which the toes are elevated
plantar flexion
movement of the foot so the toes point downward
a movement that tips the soles laterally, away from each other
extension of thumb
straightening the thumb
adduction of thumb
to bring thumb back to touch the base of the index finger
flexion of fingers
curling fingers
extension of fingers
straightening fingers
hyperextension of fingers
not possible
abduction of fingers
spreading fingers apart
adduction of fingers
bringing fingers together so they touch along their surface
a movement that straightens a joint and generally returns a body part to the zero position
the movement of a body part in the frontal plane away from the midline of the body
the movement in the frontal plane back toward the midline
raise arm high enough to cross slightly over the front/back of your head
a movement that raises a body part vertically in the frontal plane
a movement that turns the palm to face anteriorly (upward)
right rotation/left rotation
twisting at the waist/ turning of the head
medial excursion
movement back to the median, zero position
ulnar flexion
tilts the hand toward the little finger
to move the thumb to touch the tip of any of the other 4 fingers
the return to zero position
a foot movement that tips the soles medially, somewhat facing each other
pronation of the foot
a combination of dorsiflexion, eversion, and abduction, the toes are elevated and turned away from the other foot and the sole is tilted away from the other foot
supination of the foot
a combination of plantar flexion, inversion, and adduction, the toes are lowered and turned toward the other foot and the sole is tilted toward it
flexion of thumb
bending the joints so the tip of the thumb is directed toward the palm
hyperextension of the thumb
move thumb away from index finger
more powerful than pronation, do to turn doorknob clockwise
only capable of some joints, as when you stand w/ your ankles crossed, fingers crossed, or shoulder when you stand with your elbows straight and hands clasped below your waist
the anterior movement of a body part in the transverse plane
medial (internal) rotation
to place your palm against your chest, humerus exhibits this motion
lateral flexion
tilting the head or trunk to the right or left of the midline
lateral excursion
side to side movement of the mandible , movement to the left or right of the zero position
one end of an appendage remains fairly stationary while the other end makes a circular motion
