What is the function of the normal curves of the spine?

What is the function of the normal S curve of the spine?

The normal spine has an “S”-like curve when looking at it from the side. This allows for an even distribution of weight. The “S” curve helps a healthy spine withstand all kinds of stress.

What are the 3 normal curves of the spine?

The spine has three natural curves, a concave cervical and lumbar curve, and a gentle convex thoracic curve. These curves are maintained by two muscle groups, flexors and extensors.

What is the purpose of the alternating curves in the spine?

The direction of each curve (i.e. forward or back) alternates from curve to curve. This alternation helps you maintain body posture as well as negotiate challenges to your balance.

What shape is a healthy spine?

The normal spine has an S-shaped curve when viewed from the side. This shape allows for an even distribution of weight and flexibility of movement. The spine curves in the following ways: The cervical spine curves slightly inward, sometimes described as a backward C-shape or lordotic curve.

Why kyphotic curves are considered primary curves?

Why are kyphotic curves “primary curves”? Because they are present in the fetal position/the C shape. Why are lordotic curves “secondary curves”? Because they occur after birth; cervical lordosis begins when an infant begins to lift its head and lumbar lordosis begins when the baby stands erect and begins walking.

What are the primary and secondary spinal curves?

The vertebral column has four curvatures, the cervical, thoracic, lumbar, and sacrococcygeal curves. The thoracic and sacrococcygeal curves are primary curves retained from the original fetal curvature. The cervical and lumbar curves develop after birth and thus are secondary curves.
