About the Spine
The spinal column is one of the most vital parts of the human body, making all of our movements possible. Balance, posture, spinal cord protection, range of motion, shock absorption and much more are contingent on spinal health.
The normal adult spine is balanced over the pelvis, requiring minimal workload on the muscles to maintain an upright posture.
Loss of spinal balance can result in strain to the spinal muscles and spinal deformity. When the spine is injured and its function impaired, the consequences may be painful and even disabling.
Parts of the Spine
Humans are born with 33 separate vertebrae. By adulthood, we typically have 24 due to the fusion of the vertebrae in the sacrum.
The top seven vertebrae that form the neck are called the cervical spine. The seven vertebrae of the cervical spine are responsible for the normal function and mobility of the neck. They also protect the spinal cord, nerves and arteries that extend from the brain to the rest of the body.
The upper back, or thoracic spine, has 12 vertebrae, and the lower back, or lumbar spine, has five vertebrae. The lumbar spine bears the most weight relative to other regions of the spine, which makes it a common source of back pain.
The sacrum and coccyx, or tailbone, are made up of nine vertebrae that are fused together to form a solid, bony unit.
