FAQ
Frequently Asked Questions
No, it is incorrect. 'Vertebrae' is the plural form. The correct singular is 'a vertebra'.
Most adults have 33 vertebrae: 7 cervical, 12 thoracic, 5 lumbar, 5 sacral (fused into the sacrum), and 4 coccygeal (fused into the coccyx).
'Vertebra' is a single bone in the spine. 'Vertebrate' is an adjective meaning 'having a spine' or a noun for an animal that has a backbone (e.g., fish, birds, mammals).
Because the spine is a structure composed of many bones, so it's more common to refer to them collectively (e.g., 'the vertebrae are aligned') or to a specific one among many (e.g., 'the C5 vertebra') than to a single, isolated spinal bone.
