Final answer:
The term that refers to the neck is cervical. The vertebral regions ordered from closest to the head to the farthest are cervical, thoracic, lumbar, sacral, and coccygeal.
Step-by-step explanation:
The term that refers to the neck is cervical. The human vertebral column is divided into several regions: cervical, thoracic, lumbar, sacral, and coccygeal. The cervical region consists of seven vertebrae (C1-C7) and supports the head and neck.
Below these, are the thoracic vertebrae (T1-T12), followed by the lumbar vertebrae (L1-L5). The sacrum is comprised of five fused sacral vertebrae, and the coccyx, commonly known as the tailbone, is formed by the fusion of four coccygeal vertebrae.
To put the vertebral regions in order from the closest to the head to the farthest from the head, the correct sequence is cervical, thoracic, lumbar, sacral, and finally coccygeal.
