      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.
