Due to a car accident, a young woman suffered an injury to her spinal cord at first lumbar vertebra. what major function could be lost due to her injury?
a) walking
b) chewing
c) breathing
d) pushing

The correct answer will be option A-walking.

Explanation:

The spinal cord is a part of the central nervous system which carries the spinal nerves.  We depend on the spinal cord as it supports the main body posture of the body like standing upright, bending and twisting.

If this spinal cord is injured the person may suffer from various severe health implications like it will affect the walking ability as the spinal cord transmits the walking signals via neurons to the muscles in the legs which make them contract and relax. This contraction and relaxation produce the alternating movement of walking.

Thus, option A-walking is the correct answer.
