Question
A man was in an accident during which his spinal cord was severed between C6 and C7. Which of the following would NOT be a consequence of this injury?Multiple ChoiceLoss of sensation in the trunk below the shoulders, the lower limbs, and portions of the armsLoss of use of the phrenic nerves and paralysis of the diaphragmLoss of movement in the lower limbsLoss of the use of the intercostals nerves, and breathing would be affected because the intercostals muscles would be paralyzedLoss of touch sensation on the lower lumbar region.
Solution
The consequence that would NOT occur due to a spinal cord injury between C6 and C7 is the "Loss of use of the phrenic nerves and paralysis of the diaphragm".
The phrenic nerves originate from the C3, C4, and C5 spinal nerves, not C6 and C7. Therefore, an injury at the C6-C7 level would not affect the function of the phrenic nerves or cause paralysis of the diaphragm. The other options listed could potentially occur due to the injury, as they involve areas of the body that are innervated by spinal nerves at or below the level of the injury.
