Definition
The spine, also known as the backbone or vertebral column, is the central support structure of the body in vertebrates. It's a column of bones (vertebrae) that runs from the skull to the pelvis. ðĶī Think of it as the body's main support beam and protection for the spinal cord. Unlike a single bone, the spine is segmented, allowing for flexibility and movement. So, the spine is like a flexible, armored tower that holds us upright and protects our nervous system.
