Understanding Your Spine: Anatomy and Function
Learn about the complex structure of your spine and how each component works together to support movement and protect your nervous system.
Your spine is a remarkable structure that provides support, enables movement, and protects your spinal cord. Understanding spine anatomy can help you better appreciate how to maintain spine health and recognize when problems may arise.
The Three Main Regions of the Spine
Cervical Spine (Neck)
The cervical spine consists of 7 vertebrae (C1-C7) and supports the weight of your head while allowing for neck movement.
Thoracic Spine (Mid-Back)
The thoracic spine has 12 vertebrae (T1-T12) that connect to your rib cage, providing stability and protection for internal organs.
Lumbar Spine (Lower Back)
The lumbar spine contains 5 vertebrae (L1-L5) and bears most of your body weight, making it prone to injury and degeneration.
Key Spine Components
- Vertebrae: The bone segments that form the spine's structure
- Discs: Cushioning pads between vertebrae that absorb shock
- Facet Joints: Small joints that allow spine movement
- Ligaments: Tough bands that connect bones and provide stability
- Muscles: Support the spine and enable movement
