Structure of spine and vertebrae

  1. 1. Structure of Spine Lloyd Dean Skeletal System
  2. 2. Objectives By the end of the lesson you should be able to: Name the 5 curves of the spine Describe the structure and function of vertebral discus State irregularities of the spine
  3. 3. Structure of Spine What is section called? How many vertebrae are found in each? Sacrum (5) Thoracic (12) Coccyx (5 Fused) Cervical (7) Lumbar (5)
  4. 4. Structure of Invertebral Discs Fibro cartilaginous cushions Acts as shock absorbers Extension and Flexion can occur Structures: Facet Joints – Hinge like joints that link vertebrae Ligaments – Joins vertebrae and restricts hyper extension and hyper flexion Foramen – Runs down spine and houses spinal cord Nucleus Pulposus – Gel that is inside disc
  5. 5. Irregular Curvatures of Spine Kyphosis, Lordosis and Scoliosis Kyphosis Ligaments become relaxed Bone disease Pain in neck and back “Hump back” appearance Video: http://www.spinehealth.com/video /kyphosis-video-what-kyphosis
  6. 6. Lordosis Exaggerated lumbar curve Muscles around hip and spine become tight Usually trunk extensors, hip flexors and abdominals These muscles should be focussed on to repair imbalances
  7. 7. Scoliosis Spine twist or corkscrew appearance Imbalance in leg size Weakened ligaments allow abnormal curvature Not always painful Weight bearing activities can assist Reduce muscular imbalances with training
  8. 8. Scoliosis Spine twist or corkscrew appearance Imbalance in leg size Weakened ligaments allow abnormal curvature Not always painful Weight bearing activities can assist Reduce muscular imbalances with training
