Vertebral column: curvatures |
- increase resilience and flexibility of spine - cervical and lumbar curvatures - concave posteriorly - thoracic and sacral curvatures - convex posteriorly - abnormal spine curvatures - scoliosis-abnormal lateral curve - kyphosis-exaggerated thoracic curvature - lordosis-accentuated lumbar curvature |
|
|
Ligaments |
- Anterior and posterior longitudinal ligaments - from neck to sacrum - ligamentum flavum - connects adjacent vertebrae |
|
|
Intervertebral discs |
- cushionlike pad composed of two parts: - nucleus pulposus (gives disc its elasticity and compressibility) - anulus fibrosus (outer collar composed of collagen and fibrocartilage) |
|
|
General structure of vertebrae |
- body or centrum (anterior weight-bearing region) - vertebral arch - vertebral foramina (together make up vertebral canal for spinal cord) - intervertebral foramina ( lateral openings between adjacent vertebrae for spinal nerves) |
|
|
General structure of vertebrae |
