The health of the spinal column and the nerves that flow through
it are central to the Chiropractic philosophy. Doctors of Chiropractic
are specialists in evaluating the causative factors in the bio-mechanical
and structural derangements of the spine that affect the nervous
system, and in treating these derangements to restore and maintain
health. Optimum health, we believe, can only be achieved when this
relationship between the spinal column and the nervous system is
intact and allowed to function unimpaired.
The nervous system consists of the brain, spinal cord and nerves.
Nerve fibers relay impulses through this system to virtually every
cell, tissue and organ of the body, controlling all bodily functions
both voluntary and involuntary. The brain coordinates and controls
the body’s activities by sending impulses down the spinal
cord (slightly thicker than a pencil) and out the 31 pairs of spinal
nerve roots. These spinal nerves roots emerge from the spinal column
through small openings called the intervertebral foramen, which
are located on each side of each vertebrae. Spinal nerves roots
are collectively made up of thousands of nerve fibers less than
1/100th the diameter of a human hair. To help the brain know everything
in the body is functioning properly, a feedback loop sends information
from the tissues back to the brain in a system of checks and balances.
The spinal cord, the pathway for almost all nerve impulses transmitted
to and from the brain, is protected within 24 movable bones called
vertebrae, as well as the lowest bones in the spinal column called
the sacrum and the coccyx.
Several components make the back a strong, yet flexible structure.
First, each vertebrae has two bony projections called facets, which
form a hinge with the facets of the adjoining vertebrae. A thin,
soft intervertebral disc lies between two vertebrae. The intervertebral
discs consist of a tough outer layer of cartilage and an elastic
tissue, both surrounding a soft, gelatin-like material known as
the nucleus. This soft, pulpy filling enables the nucleus of the
disc to act as a shock absorber.
The combination of the vertebrae and the discs provide flexibility
in the spine. The spine’s support comes from the ligaments,
tendons and muscles that surround and attach directly to the spine.
The back is also supported by muscles in the abdomen, hips, buttocks
and legs.
The unique clinical concern in Chiropractic is the unobstructed
transmission of the spinal nerve impulses as they exit the spine.
Misalignment of the vertebrae can cause the exiting nerve to become
stretched, impinged, entrapped, compressed, pinched or otherwise
irritated. Since it is the purpose of the nervous system to coordinate
the functions of the entire body, any obstruction, no matter how
slight, can disrupt a delicate balance. This can predispose the
body to disease processes which might not have occurred had the
nerve transmission not been altered. Therefore, it can be said that
the unobstructed transmission of nerve impulses is of primary concern
to the Doctor of Chiropractic. |
