What are the 26 vertebrae names?

  • Thoracic spine: 12 vertebrae (T1–T12)
  • Lumbar spine: 5 vertebrae (L1–L5)
  • Sacrum: 5 (fused) vertebrae (S1–S5)
  • Coccyx: 4 (3–5) (fused) vertebrae (Tailbone)

What are the 5 vertebral sections?

Sections. The spine is composed of 33 bones, called vertebrae, divided into five sections: the cervical, thoracic, and lumbar spine sections, and the sacrum and coccyx bones. The cervical section of the spine is made up of the top seven vertebrae in the spine, C1 to C7, and is connected to the base of the skull.
