The Back

Overview

The back provides the central support for the body and protects the spinal cord. This section introduces the structure and function of the vertebral column, paraspinal muscles and associated ligaments, establishing the framework for understanding posture and movement.

Key Structures

Topics include the vertebrae and intervertebral joints, the spinal cord and meninges, and the superficial and deep muscle layers. Diagrams and clinical notes highlight key anatomical relationships that underpin spinal movement and neural protection.

Clinical Relevance and Learning Focus

Mastering spinal anatomy supports diagnosis and treatment of back pain, disc herniation and spinal cord injury. The section links anatomy with biomechanics and clinical practice, helping learners interpret examination findings and imaging with precision.
