Question

the vertebral column is composed of 33 bones before ____ ; some later fuse to form ____ separate bones.

Answer 1

The vertebral column is composed of 33 bones before fusing; some later fuse to form 26 separate bones.

The vertebral column, also known as the backbone or spine, is a long, flexible column of bones extending from the skull to the tailbone. It is made up of 33 vertebrae, separated into five sections: the cervical, thoracic, lumbar, sacral, and coccygeal. In between each vertebra is a disc of cartilage that acts as a shock absorber, allowing the bones to move independently of one another.

The vertebral column also houses the spinal cord, which is a bundle of nerves that runs from the brain to the lower back. It is responsible for transmitting signals to and from the brain and body.
