Analysis and explanation
According to the NCERT text, the spinal cord is a delicate structure containing nerves that supply information to the brain and coordinate reflex actions. It is protected by a hard, bumpy bony structure running down the middle of the back, known as the vertebral column or backbone.
Interesting facts
The vertebral column is made up of 33 individual bones called vertebrae in children, which fuse to form 26 bones in adults, providing both flexibility and robust protection to the spinal cord.
