CURVATURES OF THE VERTEBRAL COLUMN:
The Cervical vertebrae form a forward curve called a "Lordotic curve".
The Thoracic vertebrae form a curve backward called a "Kyphotic curve.
The Lumbar vertebrae form a forward curve like the cervical called the "Lordotic curve"
The Lumbar vertebrae form a forward curve like the cervical called the "Lordotic curve"
The Sacrum and Coccyx, like the thoracic vertebrae form a curve with concave anterior border.
An exaggerated thoracic curve is called "Kyphosis" or “Hunchback"
An exaggerated lumbar curve is called "Lordosis" or "Swayback".
"An appreciable lateral deviation of the normal alignment of the vertebral column is called “Scoliosis”
A combined lateral (scoliosis) and posterior (kyphosis) curvature of the spine is called "Scoliokyphosis" or "Kyphoscoliosis".
