The intervertebral disc is a crucial component of the vertebral column, uniting adjacent vertebrae and enabling limited movement while providing structural support. Positioned between the vertebral bodies, these discs form an amphiarthrosis joint, allowing slight motion, and are composed of fibrocartilage, classifying them as a symphysis type of cartilaginous joint. This article delves into the anatomical structure of the intervertebral disc, its biomechanical role, and its clinical significance, offering a comprehensive understanding of its function in the spine.

The intervertebral disc and cartilaginous joints represent crucial components of spinal anatomy, providing both stability and flexibility to the vertebral column. Understanding their complex structure and function is essential for medical professionals in neurology, orthopedics, and spine surgery.

The spine represents a complex structure where various pathological changes can significantly impact patient quality of life. Understanding the progression from normal disc anatomy to various pathological states is crucial for healthcare providers in diagnosing and treating spinal conditions effectively.
