Intervertebral Disc Anatomical Structure: Lateral View and Clinical Insights
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.

Axis (C2) Vertebra: Comprehensive Analysis of the Epistropheus from Superior View
The axis, or second cervical vertebra (C2), represents a unique and specialized component of the vertebral column, distinguished by its distinctive odontoid process (dens). This superior view demonstrates the complex architecture that enables rotational movements of the head while maintaining stability. The axis serves as the pivot point for head rotation and forms crucial articulations with both the atlas above and the third cervical vertebra below.
Iliac and Anterior Femoral Muscles: A Comprehensive Anatomical Guide
The iliac and anterior femoral regions contain a complex array of muscles essential for lower limb movement and stability. These muscle groups play crucial roles in hip flexion, knee extension, and maintaining upright posture. Understanding their anatomical relationships and functions is fundamental for medical professionals in diagnosing and treating various musculoskeletal conditions affecting the lower extremity.
Upper Cervical Spine: Comprehensive Analysis of Ligamentous and Osseous Relationships
The median sagittal section through the craniovertebral junction reveals the intricate relationships between osseous structures and ligamentous complexes that enable controlled head movement while maintaining stability. This critical region demonstrates sophisticated anatomical arrangements that protect vital neural structures while facilitating complex motion patterns between the skull and upper cervical vertebrae.
