Answer
Small boney units; Squashy bits in between the bones
Explanation
Vertebrae are small, interlinked, bony units typically stacked on top of each other to form the vertebral column or 'backbone'. They primarily play a role in providing support to the body, forming a protective canal for the spinal cord, and allowing varied movements. Nervous messages from the brain to the other body parts are mediated by the spinal cord, not the vertebrae themselves. The 'squashy bits' referred to in the question typically refer to the intervertebral discs located between adjacent vertebrae; these serve as shock absorbers during physical activity and provide flexibility to the spine. Therefore, two statements are accurate about vertebrae while one is not.
