Which one is true

Answer 1

The statement that is true is cervical 7, thoracic 12 and lumbar 5

Step-by-step explanation:

The statement refers to the number of vertebrae in each segment of the spine, cervical, thoracic and lumbar.

The vertebrae are each of the bony structures that are united to form the spine. The complete count of vertebrae in humans is

• Cervical, 7 vertebrae.
• Thoracic, 12 vertebrae.
• Lumbar, 5 vertebrae.

In addition, the sacral bone is formed by 5 fused vertebrae and the coccyx has 4 small vertebrae.

The other options, in the human, are not possible.
