Final answer:
Intervertebral discs and the spring-like construction of the vertebral column support the spinal cord and enhance flexibility.
Step-by-step explanation:
The presence of the intervertebral discs and the spring-like construction of the vertebral column supports the spinal cord and enhances flexibility.
The intervertebral discs are made of fibrous cartilage and act as cushions to absorb shocks from movements like walking and running.
They also serve as ligaments to bind the vertebrae together.
The spring-like construction allows for some movement of the spine and helps with overall flexibility.
