25
Q

Flexion and extension

A

Occurs in saggital plane. Flexion- anterior/forward movement
Extension- posterior/backward
(think bending back or forward)

26
Q

Abduction and Adduction

A

works within frontal plane
Abduction- moving something latertally away from the body
Adduction- bringing something back towards the body
(think shoulder joint)

Occurs in the forearm directing the position of the radius and ulna
Supination- radius and ulna are parellel (front facing palm)
Pronated- radius and ulna make X shape (backwards palm)

30
Q

Dorsiflexion and Plantar Flexion

A

Occurs at ankle joint
Dorsiflexion- tilting the foot up towards the tibia
Plantar flexion- pointing toe towards the ground

31
Q

Inversion and Enversion

A

Multiple joint movement that brings the joint towards or away from the midline of the body
Inversion- going towards the midline
Eversion- away from the midline

32
Q

Protraction and Retraction

A

Movements of the scapula or mandible
Protraction- shoulder is moved foward
Retraction- shoulder is moved back

33
Q

Depression and elavation

A

Upwards and downwards movement of the mandible and scapula
