The spinal column, also known as the vertebral column or backbone, is a vital structure in the human body that provides support, protection, and flexibility. It is a complex assembly of bones, discs, nerves, and muscles. Below is a detailed description:
Structure of the Spine
The spine consists of 33 vertebrae, divided into five regions:
1. Cervical Spine (Neck Region)
• 7 vertebrae (C1–C7)
• Supports the head and allows for movement such as nodding and rotation.
• Notable vertebrae:
• C1 (Atlas): Supports the skull.
• C2 (Axis): Enables head rotation.
2. Thoracic Spine (Upper Back)
• 12 vertebrae (T1–T12)
• Attached to the ribs, forming the ribcage to protect organs like the heart and lungs.
3. Lumbar Spine (Lower Back)
• 5 vertebrae (L1–L5)
• Bears the weight of the upper body and provides flexibility and movement.
4. Sacral Spine (Pelvic Region)
• 5 fused vertebrae (S1–S5)
• Forms the back of the pelvis, providing stability and connecting the spine to the hips.
5. Coccyx (Tailbone)
• 4 fused vertebrae
• Acts as an attachment point for muscles and ligaments.
Intervertebral Discs
• Located between vertebrae, these cartilage structures act as shock absorbers and allow flexibility.
• They consist of:
• Nucleus Pulposus: The soft, gel-like core.
• Annulus Fibrosus: The tough outer layer.
Spinal Cord and Nerves
• The spinal cord runs through the spinal canal, protected by the vertebrae.
• It is part of the central nervous system, transmitting signals between the brain and the rest of the body.
Functions of the Spine
1. Support: Provides the framework for the body, supporting the head, shoulders, and torso.
2. Movement: Enables a wide range of motion, including bending, twisting, and stretching.
3. Protection: Safeguards the spinal cord and surrounding nerves.
4. Flexibility and Shock Absorption: Discs and curves in the spine absorb shocks during activities like walking and running.
Curves of the Spine
• The spine has natural curves that enhance its strength and balance:
• Cervical and Lumbar (Lordotic Curves): Inward curves.
