‼️It’s World Spine Day‼️Here are some interesting facts for you about the spine. 📝(thanks @drledda)

1. When we’re born, our spines consist of 33 individual vertebrae.
2. As we age, some of these vertebrae fuse together. The five vertebrae composing our sacrum become one bone and the coccygeal vertebrae – which can vary from three to five bones – fuse together as one. Thus, the tailbone is formed.
3. You have twelve vertebrae in your thoracic area – the middle portion of the back. You have five vertebrae in your lumbar spine area – the lower back. And the cervical area, or the neck, is comprised of seven individual vertebrae.
4. An interesting fact about the first cervical vertebrae is that it is sometimes referred to as Atlas, referencing the Greek mythological Atlas who carried the world on his shoulders.
5. There are 120+ muscles are contained in the spine.
6. It includes approximately 220 individual ligaments.
7. These ligaments keep the vertebrae interconnected which keeps the spine, as well as the nerves it’s protecting within the spinal cord, stable.
8. Over 100 joints allow for the spine’s extreme flexibility and range of movement.
9. Over one fourth of the spine’s total length is created from cartilage, the sponge-like substance that separates one vertebral disc from the next.
10. Cartilage can expand and contract. Interestingly, if gravity is removed (in space travel, for example) a person can return to earth taller than when he or she left. Oppositely, gravity’s pull on our bodies over the years shrinks cartilage, making us decrease in height as we age.
11. Backbones are surprisingly strong, however, and they can sustain the weight and pressure of hundreds of kilograms.
12. The spine has an excellent memory, and as such, it’s recommended that you take care to provide it with proper support from a young age. Controlling your posture, engaging in strengthening the back muscles, as well as stretching are all beneficial to the long-term health of your spine.
