Study Notes

Introduction to the Vertebral Column

The vertebral column, also known as the spinal column, serves multiple important functions:
- Protection: Encloses and protects the spinal cord within the spinal canal.
- Support: Bears the weight of the body above the pelvis.
- Axis: Acts as the central axis of the body.
- Movement: Facilitates posture and movement.
- Attachment: Provides attachment points for muscles, tendons, and ligaments.

Composition of the Vertebral Column

Composed of 33 bones:
- 7 cervical vertebrae (neck)
- 12 thoracic vertebrae (chest)
- 5 lumbar vertebrae (lower back)
- 5 sacral vertebrae (fused)
- 4 coccygeal vertebrae (fused into the coccyx)
Spine appears S-shaped when viewed laterally.

Specific Vertebrae

C1 (Atlas):
- First vertebra, ring-shaped, supports the skull.
C2 (Axis):
- Second vertebra, allows rotational movement of the head.
C7 (Prominens):
- Seventh cervical vertebra, characterized by a large spinous process.

Curvatures of the Vertebral Column

Anterior Concavities: Present in the thoracic and sacral regions (kyphoses), developed during the fetal period.
Posterior Concavities: Found in the cervical and lumbar regions (lordoses), formed after birth.

Scoliosis and Other Conditions

Scoliosis:
- An abnormal lateral curvature of the spine, often diagnosed in childhood or early adolescence.
- More common in females than males.
The etiology of scoliosis is often unknown and may not be related to a specific underlying condition.

Learning Activities

Understanding the distinct roles of different vertebrae helps to grasp the overall functionality of the spinal column.
Identification of anterior and posterior curvatures contributes to an understanding of spinal mechanics and health.
