The backbone is not a single bone. It is made up of ____bones.

• A. 33
• B. 34
• C. 35
• D. 36

Answer 1

The correct option is A 33

The normal average person is born with a total of 33 vertebrae in the vertebral column (backbone). By the time the person becomes an adult, some bones fuse and the number is reduced to 24. The articulating vertebrae are named according to their region of the spine. There are seven cervical vertebrae, twelve thoracic vertebrae, and five lumbar vertebrae.

Hence the correct answer is option A.
