The cervical spine is located at the top of the spine and comprises the first seven vertebrae, labeled C1 through C7. This region is commonly referred to as the neck. It supports the head and allows for a wide range of motion, including nodding and rotation. Understanding the structure and function of the cervical spine is essential for fitness professionals because it plays a significant role in overall posture and movement mechanics.

The thoracic spine, on the other hand, is located below the cervical spine and consists of twelve vertebrae, serving as an attachment point for the ribs. The lumbar spine is situated in the lower back, consisting of five larger vertebrae that primarily support the weight of the upper body and aid in activities such as bending and lifting. The sacral region is further down and consists of fused vertebrae forming a triangular shape at the base of the spine. Each of these regions has distinct functions and anatomical features, but none of them are described as the "upper back or neck" like the cervical region is.
