Anatomy of the spine

The spine, or backbone, is a vital structure in the human body, consisting of 33 vertebrae divided into regions: cervical (neck), thoracic (mid-back), lumbar (lower back), sacral (pelvic area), and coccygeal (tailbone). These vertebrae are separated by intervertebral discs that provide cushioning and flexibility. The spine protects the spinal cord, a crucial nerve pathway, and supports the head, allowing for movement and stability. Ligaments and muscles surround the spine, aiding in support and movement, while its natural curves enhance strength and balance. Overall, the spine plays a key role in posture and overall body function.
