The spine is a set of 33 vertebrae and is connected to the brain (the other component of the CNS).
There are 3 main functions of the spine:
- Movement and Flexibility – Since the spine is made up of 33 vertebrae, the spine can flex in every direction. This allows humans to do simple tasks that we take for granted every day such as bending over, standing and even walking.
- Structural Support, Posture and Balance
- Protection for the Spinal Cord and Internal Organs
