Lecture 17 - Anatomical Terms For Movement Flashcards
Flexion
Bending of Joint
Extensions
Straightening Joint
Dorsiflexion
Decreasing angle of ankle joint
‘Dorsi’ = back
Imagine your trying to pull your toes back
Plantarflexion
Increasing angle of the angle joint
Pointing toes into floor
Elevation
Moving body part in superior direction
Depression
Moving body part in an inferior direction
Eversion
Rotating ankle so sole of the foot points away from other
Foot is EVading other foot
Inversion
Rotate ankle so sole of foot points to other foot
Abduction
Moving limb away from centre line of body
(Limb abducted away)
Adduction
Movinglimb towards centre line of body
Lateral Rotation
Rotating a limb away from the centre line
Medial Rotation
Rotating a limb towards (medial line) centre of body
Pronation
Rotating forearm so that the palm faces down if forearm is flexed
If you’re PRONE you are laying down facing floor
Palm faces floor
Supination
Rotating the forearm so that the palm is facing up if the forearm is flexed
If you are lying supinated your body is facing UP cuz you’re SUPerior
Palm faces UP
Retraction
Posterior movement (towards the back of the body) of the ARM at the SHOULDER
Protraction
Anterior movement (towards front of body) of the ARM at the SHOULDER
Lateral Flexion
Bending the spine to the side away from the centre line of body
What is Circumduction?
A combination of Flexion, extension, ABduction and ADduction
A combination of joint flexing bent, joint straightening, limbs moving away from medial line and limbs moving back towards medial line.
What type of movement does Circumduction cause?
Circular Movement
When describing hand movement, where is considered to be the midline?
Running down the middle of the middle finger
For the hand what is abduction?
When finger or thumb moves away from medial line
What is thumb ABduction?
When thumb moves away from plane of the hand (palm)
Also called palmar ABduction
Thumb ADuction
When Thumb returns back to the plane of the hand
What is thumb opposition?
When thumb can oppose/touch other digits
Reposition
Opposite of Opposition
Both Thumb and digit return
Finger Flexion differs to Thumb Flexion how?
Finger Flexion happens in Sagittal Plane
Thumb Flexion happens in the Coronal/Frontal Plane
Why does the plane of Flexion differ between the thumb and fingers
The thumb is rotated 90 degrees relative to the other fingers during development
Flexion of elbow brings forearm anteriorly
But Flexion of knee moves leg posteriorly
WHY IS THIS THE CASE?
During Fetal Development:
Upper limbs rotate OUTWARDS (Remember arms reach out)
Lower limbs rotate INWARDS
What plane does Flexion and Extension occur in?
Sagittal Plane (side on view)
What plane does ABduction and ADuction occur in?
Coronal/frontal plane
What plane does lateral and medial rotation occur in?
Transverse plane
