Anatomy of the Spine
The spine also called the backbone, is made up of vertebral bones with cushioning intervertebral discs between them. The spine is designed to give us stability and smooth movement, as well as providing a corridor of protection for the delicate spinal cord.
Cervical Spine Anatomy
The cervical spine is highly mobile compared to the thoracic or lumbar spine. In contrast to other parts of the spine, the cervical spine has transverse foramina in each vertebra through which the vertebral arteries supply blood to the brain.
Thoracic Spine Anatomy
The thoracic spine is the central part of the spine, also called the dorsal spine, which runs from the base of the neck to the bottom of your rib cage. The thoracic spine provides the flexibility that holds the body upright and protects the organs of the chest.
Lumbar Spine Anatomy
The lumbar spine is composed of the lower 5 vertebrae, which have been numbered L1–L5. The lowest vertebra of the lumbar spine (L5) is connected to the top of the sacrum, which is a triangular bone present at the base of the spine fitting into the two pelvic bones.
