Question

why does spine have curved shape?
​

Answer 1

Answer:

From top to bottom, an ideal spine has an outward-inward-outward curve, thus taking the shape of an S. First and foremost, proper curvature of the spine gives it flexibility and creates support. The offsetting curves of each section create a spring-like structure, enabling the spine to act as a natural shock-absorber.
