Document Summary

In kids there is an exaggeration of the lumbar curvature: curvatures can also progress and become exaggerated with age, hunchback (kyphosis) results in the thoracic region. Lordosis - exaggeration at the lumbar region: movement of the spine away from the midline laterally - scoliosis, often occurs in the thoracic region. Primary curvatures: are present at birth: thoracic curvature. Secondary curvatures: form after birth: cervical curvature - from holding the head up straight. Lumbar curvature - from the process of walking. First 7 vertebrae: concave from a posterior view, convex - anterior view. Thoracic: 12 vertebrae, convex from a posterior view, concave - anterior view. Lumbar: 5 vertebrae, concave from a posterior view, convex - anterior view. Sacral and coccyx region: 4 fused vertebrae, convex from a posterior view, concave - anterior view. Typical vertebrae: typical vertebrae have a certain number of typical features and atypical vertebrae lack at least one of these features.
