What is an advantage of the configuration of the spine?
Multiple displacements of small linkages = more stable than large displacements
What are the names of the types of curves found in the spine?
Which parts of the spine have which types of curves?
Cervical = lordosis
Thoracic = kyphosis
Lumbar = lordosis
Sacral = kyphosis
Look at the structure of the vertebrae in your notes and name each part.
