Human Spine Anatomy Diagram - Structure, Vertebrae, and Posture #3863187 (License: Personal Use)

This medical illustration depicts the human spine in sagittal view, clearly distinguishing the five vertebral regions: cervical (7 vertebrae), thoracic (12), lumbar (5), sacral (5 fused), and coccygeal (3-5 fused). The natural curves-cervical lordosis, thoracic kyphosis, lumbar lordosis, and sacral kyphosis-are shown to reflect proper posture and biomechanical function. The image is ideal for educational, clinical, or wellness contexts where spinal anatomy and alignment are discussed.

Commonly used on health education websites, orthopedic or chiropractic practice pages, anatomy textbooks, and patient-facing resources explaining back pain, posture, or spinal disorders. Matches user intent for learning basic spinal structure or understanding spinal health.
