Answer:
The correct answer is quadriplegia.
Explanation:
The paralysis of both the legs and arms has been known as quadriplegia. The main reason for quadriplegia is the injury to the spinal cord, however, other conditions like strokes and cerebral palsy can also result in similar paralysis. The degree of damage depends upon the part of the spinal cord injured and the amount of destruction done.
With the injury to the spinal cord, the brain loses the tendency to communicate with it and so the movement and sensation get impaired. Quadriplegia takes place when the region of the neck of the spinal cord gets injured like a C3 fracture. An extreme spinal cord injury may obstruct the process of breathing and hampers the movement of limbs.
An individual with complete quadriplegia loses the tendency to move any part of the body underneath the neck, even some are not able to move their neck.
The combination is the one we see is physical and the author one that we can’t see is unphysical
