Description:
The spinal column is composed of 33 bones (called vertebrae) spanning from the base of the skull to the pelvis. Each vertebra has a round, solid body and a bony arch. The spinal cord runs through the hole between the arch and the body of the vertebra and is thus protected by bone on all sides. A pair of spinal nerves (one on the right and one on the left) runs out between every vertebra. Soft intervertebral disks separate the bodies of the vertebrae, and the arches are connected to one another through joints called facets. The part of the spine in the neck is called the cervical spine and consists of 7 vertebrae and 8 pairs of spinal nerves (called C1 to C8 for cervical nerves 1 through 8). The two most common problems people have with the cervical spine are disk herniation and stenosis. Normally a vertebral disk has a fibrous outer "rind" and a soft interior, somewhat like a thick-skinned orange. When a disk herniates, the soft inside material squeezes out through a break in the rind and can pinch the nerves as they exit the spinal column. This will cause pain and sometimes weakness and numbness in the neck and arm. Spinal stenosis occurs when the facet joints develop arthritis and start to grow excess bone around them (a typical response of a joint to arthritis). The extra bone narrows the space through which the spinal nerve exits the spinal column. This can lead to weakness and pain in the neck and arms.
