What area of the body is affected by cervical spinal cord injuries?

• A. Only the arms
• B. Only the legs
• C. Both arms and legs
• D. Only the middle of the body

Answer: (C)

Cervical spinal cord injuries impact the area of the body governed by the cervical region of the spine, which is located in the neck. Injuries in this area can disrupt the neural pathways that control various muscle groups. Since the cervical spinal cord segments are responsible for innervating not just the arms but also the legs, any damage can lead to loss of motor function and sensation in both. In fact, the cervical spine controls the upper extremities (arms) as well as the lower extremities (legs) depending on the level of the injury. An injury occurring higher in the cervical spinal cord, such as at C1 or C2, can lead to tetraplegia or quadriplegia, which affects all four limbs, while injuries lower down, such as at C6 or C7, might still enable some arm function but still impact leg function. This is why the correct answer highlights that both arms and legs are affected by cervical spinal cord injuries.
