16

what are the osteokinematics of the glenohumeral joint

fex/ext, abd/add, rotation

17

describe roll and slide in shoulder flexion

roll - superior rotation about mediolateral axis
slide - inferior translation

18

describe roll and slide in abduction at the shoulder joint

roll - superior rotation about the anteroposterior axis
slide - inferior translation
