Final answer:
The spinal segments, ranked from most superior to most inferior, are cervical, thoracic, lumbar, sacral, and coccygeal, starting with the cervical region closest to the head.
Step-by-step explanation:
To rank the vertebral regions from most superior to most inferior, with the most superior on top, we need to consider their position along the vertebral column. Starting from the closest to the head:
- Cervical
- Thoracic
- Lumbar
- Sacral
- Coccygeal
The vertebral column begins with the cervical region at the top, which is nearest to the head and contains seven vertebrae (C1-C7). This is followed by the thoracic region with twelve vertebrae (T1-T12), then the lumbar region with five vertebrae (L1-L5), succeeded by the sacral region consisting of five fused sacral vertebrae, and finally the coccygeal region at the bottom with four fused coccygeal vertebrae.
