Question

Q4. 6) difference between the Spine and spinal cord​

Answer 1

Explanation:

The spine is made up of a column of bones called vertebrae (spinal column). The spinal cord, a long, fragile structure contained in the spinal canal which runs through the centre of the spine, is protected by the vertebrae.

Answer 2

• Spinal Cord is the tube-like structure which consists of bundles of nerve fibers. It is covered by the meninges and is surrounded by the cerebrospinal fluid.
• Backbone or the spinal column is the central axis of the skeleton in all vertebrates. In a newborn human, there are about 33 bones that make up the spinal column. By the time the newborn becomes an adult, the number of bones reduces to 24 as they fuse during normal growth and development.
