<prompt> In a diving accident that severed the spinal cord below the sixth cervical veebra, which of the following muscle would be affected?DeltoidInfraspinatusLatissimus DorsiLevator Scapulae  <response>: If the spinal cord was severed beneath the 6th cervical veebra, all nerve roots below C6 would be affected. So, latissimus dorsi, which is innervated by the thoracodorsal nerve C6, C7, C8 would be affected.Deltoid is supplied by the axillary nerve C5, C6. Infraspinatus is supplied by the suprascapular nerve C5, C6. Levator Scapulae is supplied by the dorsal scapular nerve C5. Trapezius Is supplied by the accessory nerve CN XI.
