  • Summary

  • General Structure of the Vertebra

    Each vertebra has the following parts:

    1. **Corpus vertebrae**: The main body, filled with spongy bone and red marrow, supporting weight.

    2. **Arcus vertebrae**: The vertebral arch, attached to the body, protecting the spinal cord.

    3. **Processus spinosus**: The spinous process, a bony projection from the arch, providing muscle attachment.

    4. **Processus transversi**: Lateral projections for muscle attachment.

    5. **Foramen vertebrae**: The vertebral foramen, a hole housing the spinal cord.


    ### Divisions of the Spine:

    1. **Cervical Vertebrae (C1-C7)**: Neck vertebrae allowing significant movement. The **Atlas (C1)** supports the skull, and the **Axis (C2)** enables head rotation.

    2. **Thoracic Vertebrae (T1-T12)**: Chest vertebrae, supporting the ribs.

    3. **Lumbar Vertebrae (L1-L5)**: Lower back vertebrae, larger and designed for weight-bearing.

    4. **Sacrum**: A triangular bone formed by the fusion of five sacral vertebrae, connecting the spine to the pelvis.

    5. **Coccyx**: The tailbone, formed by fused coccygeal vertebrae, has no arches but retains small projections.
