"KNOWLEDGE OF VERTEBRAL COLUMN OR SPINAL CORD"

VERTEBRAL COLUMN OR SPINAL CORD;

There are thirty-three  vertebrae :
A.
 Cervical vertebrae are seven in number. Of them the first one carries the weight of the skull and helps in moving the head in different directions and to bend the neck.


B. Thoracic vertebrae are twelve in number.They help in twisting and bending the body.

C. Lumbar vertebrae are five in number.They help in turning the body in a circular way.

D. Five vertebrae are fused into one and form the Sacral bone.

E. Four vertebrae are fused into one and form the Coccygeal bone.
     Though vertebrae form into a column they are not placed one upon another. There are gaps between every two of them. These gaps are filled up with cartilage and synovial fluid and spinal cord passes within it. In case of any damages or disturbances  to the spinal cord, the flow of electricity to the connecting organs is disturbed. Spinal cord divided in two parts from lumber ;one in right and other is left side of leg upto toes. Sometime nerves are damaged due to jerks, lifting of heavy things, wearing of high heeled shoes etc. and  pain goes to leg either posteriorly or sideways called sciatic nerves pain. So it is very essential to sit erect and do flexion and extension Exercises daily.
