Therotation may mask the displacement outwards, due tothe paralysis of the lowest part. If the clavicular partremains, there may be no rotation, but the scapula islower than normal. The Bhoinboids (fifth cervical nerve, by a branchthat passes through the scalenus) first rotate the scapulaon the outer angle, moving the lower angle inwards,and then move the whole scapula upwards and strong elevation, they aid the trapezius, which pre-vents the rotation of the scapula. The rotatory actionaids forcible depression of the raised arm. The musclesalso fix the scapula for the action of the teres tone helps to keep the scapula against the thorax (opposing the pectoralis)and in its vertical position (opposing the serratus), and hence, in paralysis, the.
