Cervical Spine Anatomy

The cervical spine is highly mobile compared to other regions of the spine such as 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

Thoracic spine is the central part of the spine, also called as dorsal spine, which runs from the base of the neck to the bottom of your rib cage. The thoracic spine provides 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. In some cases, an extra or sixth lumbar vertebra may be present.
