Your spine is made up of a series of interconnected bones, each on top of the other, that provide numerous benefits to the body including:
- Shock absorption
The spine delivers these benefits through its spinal curves.
During fetal development in the womb, the spine has only one curve, a C-shaped curve, called a kyphotic curve. Later, as a baby begins to experience significant motor development, such as sitting, crawling and walking, muscles begin to develop. As these muscles strengthen, they allow more weight to be shifted to the baby’s spine, causing the formation of secondary curves, called lordotic curves. These curves continue to develop as the child grows.
Four types of spinal curves:
- Cervical Lordosis
- Thoracic Kyphosis
- Lumbar Lordosis
- Sacral Kyphosis
These curves are important because they allow the spine to support 10 times more weight than it could if it were straight. This also explains why it is important to follow the procedures associated with proper lifting. If you bend at the waist to pick something up, the spine straightens, putting you at far greater risk for injury than if you bend at the knees, maintaining the spinal curves, when lifting.
