Final answer:
No, a "crush" injury to the thoracic region does not have to be bilateral in nature. It can affect only one side of the thoracic region, resulting in unilateral damage.
Step-by-step explanation:
No, a "crush" injury to the thoracic region does not have to be bilateral in nature. This means that it can affect only one side of the thoracic region, resulting in unilateral damage. For example, if there is a hemisection (half-section) of the spinal cord in the thoracic region, it can cause paralysis or loss of motor control in one leg, while the other leg remains unaffected. This is known as hemiplegia.
