6.12 joints and types of movement Flashcards
a simple movement; the nearly flat surfaces of
bones move back-and-forth and side-to-side.
gliding
there is an increase or decrease in
the angle between bones
* Ex: flexion–extension
angular movements
where a bone moves around its own
longitudinal axis
rotation
occur only at certain joints in the body.
* Ex: elevation–depression
special movements
decreases the angle between bones of the limb at the joint
flexion
increases the angle between bones of the limb at the joint
extension
extends the joint beyond the normal range of motion
hyperextension
movement of limb
away from midline of
body
abduction
movement of limb
toward the midline of
body
adduction
movement of limb so that the distal end forms a circle
Circumduction
turning the body part around the long axis
rotation
gains results in _____ production of ____ fluid in joints
decreased, synovial
articular _____ becomes thinner with age and ligaments shorten and lose flexibility
