Protraction is shoulders moving forward and Retraction is shoulders back

Question 22

Depression/Elevation

Answer 22

Depression is shoulders going down and Elevation is them going up

Question 23

Opposition/Reposition

Answer 23

Opposition is thumb and index touching and reposition is back to normal
