The thoracic spinal cord contains all which nuclei?

Explanation:
This question is testing how the spinal cord is organized to control different muscle groups. The thoracic region is mainly involved with axial (trunk) muscles, so the neurons that innervate those muscles are located in the thoracic spinal cord. In other words, the nuclei related to trunk control—the axial nuclei—are found there, making axial the best match. Cranial nuclei are located in the brainstem, not the spinal cord. The limbic system is a brain structure, not a spinal nucleus. The spinal accessory nucleus is in the cervical portion of the spinal cord, not the thoracic.
