An individual accidentally transected (cut across) the spinal cord between C1 and C2. This would result in

A. Quadriplegia

B. Spinal shock only

C. Paraplegia

D. Hemiplegia

Answer

A. Quadriplegia

Step-by-step explanation

The C1 and C2 vertebrae are the first two sections in the cervical spine that support the head. The C1 vertebra pivots on the C2 vertebra which enables the head to rotate. Damage to the spinal cord at the C1 and C2 vertebral levels is severe and entails the loss of function to the neck and everything below, which may result in partial or full paralysis, thus fatal. When an individual suffers from full or partial paralysis from the neck down the trunk, and all four limbs, it is commonly called quadriplegia. Hence option A is correct.

Spinal shock is caused by damage normally above the T6 section of the spinal cord. Hence option B is incorrect. 

Paraplegia is a result of damage at the T9 - T12 vertebrae levels. Hence option C is incorrect. 

Hemiplegia is caused by damage normally above the C6 section of the spinal cord. Hence option D is incorrect.
