Translations:Wirbelsäule/5/en

The spine of an adult is divided into four sections: Cervical spine, thoracic spine, lumbar spine and sacral spine (os sacrum). Accordingly, in humans it also has four typical curves in the sagittal plane. These curvatures dampen shocks when walking or falling on the feet or the spine.
Each section is made up of individual vertebrae:

• 7 Cervical vertebrae
• 12 Thoracic vertebrae
• 5 Lumbar vertebrae
• 5 Sacral vertebrae

The vertebral bodies support or carry the spine. Another important task is the formation of blood cells in their bone marrow. The cervical, thoracic and lumbar spine is also known as the presacral spine. The transition regions between the parts of the spine are a weak point for spinal diseases.
