What are the pathological bends of the spinal column?
Scoliosis is a lateral, or sideways, deviation of the spine, or vertebral column. The condition usually includes two curves—the original abnormal curve and a later-developing compensatory curve.
What are the 4 major curves of the vertebrae?
When observed from the side the vertebral column has four major curves. The curves correspond with each group of vertebrae, and are: the cervical curve, the thoracic curve, the lumbar curve and the pelvic curve (formed by the sacrum and coccyx).
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 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.
What are the two primary curves of the spinal column?
The vertebral column is curved, with two primary curvatures (thoracic and sacrococcygeal curves) and two secondary curvatures (cervical and lumbar curves).
Is spinal curvature reversible?
As in a normal spine, the curvature, rotation of vertebrae, and associated torso imbalance are flexible and reversible, and there is no deformation of vertebral bodies (triangle).
Which condition is an abnormal curvature of the spine?
Types of sagittal imbalance include kyphosis, flatback syndrome, and chin-on-chest syndrome. Abnormal curvature of the spine seen from the back is called scoliosis.
What are the terms for the curvatures of the spine?
There are three main types of spine curvature disorders, including:
- Lordosis. Also called swayback, the spine of a person with lordosis curves significantly inward at the lower back.
- Kyphosis. Kyphosis is characterized by an abnormally rounded upper back (more than 50 degrees of curvature).
What are two functional reasons for the natural curves of the human spine?
First and foremost, proper curvature of the spine gives it flexibility and creates support. The offsetting curves of each section create a spring-like structure, enabling the spine to act as a natural shock-absorber.
