vertébral

Vertébral refers to the spine or backbone, which is a crucial component of the vertebrate skeletal system. The spine is composed of a series of vertebrae, individual bones that are stacked one on top of the other, providing structural support and protection for the spinal cord. The vertebrae are connected by intervertebral discs, which allow for flexibility and movement, and are further stabilized by ligaments and muscles.

The spine is typically divided into five regions: the cervical (neck), thoracic (chest), lumbar (lower back), sacral (pelvic), and coccygeal (tailbone). Each region has specific functions and characteristics. The cervical spine supports the head and allows for neck movement, while the thoracic spine protects the heart and lungs. The lumbar spine bears the majority of the body's weight and facilitates movement of the lower body. The sacral and coccygeal regions form the pelvic area and the tailbone, respectively.

The spine plays a vital role in maintaining posture, facilitating movement, and protecting the spinal cord, which is responsible for transmitting signals between the brain and the rest of the body. Injuries or conditions affecting the spine, such as herniated discs, spinal stenosis, or scoliosis, can lead to pain, mobility issues, and other health problems. Proper care, including exercise, ergonomics, and medical intervention when necessary, is essential for maintaining spinal health.
