Human Anatomy

The spinal cord is located in the spinal column, which is comprised of 24 movable bones known as vertebra. This design allows our spines flexibility in all directions: bending forwards, backwards, sideways and rotating to either side. The spine is not straight, but has three curves to carry the weight of the head, trunk and extremities. The middle back (thoracic) curve with 12 vertebrae is the primary curve of the spine; we develop it while in the fetal position in the womb. The neck (cervical) curve has 7 vertebrae and develops as we learn to lift our heads while crawling. The lower back (lumbar) curve has 5 vertebrae and develops as we begin to stand and walk.

The spinal curves are an evolutionary response to gravity's forces on the human body and can be compared to the arches of a bridge. Just like the bridge, these curves allow the spine to support far more weight than if it were straight.

The spinal cord transmits electrical impulses from the brain to every cell in the body by way of millions of nerves. The proper functioning of the spinal column and spinal cord is very important for good health.


Without adequate spinal flexibility and normal neurological transmission it is possible to fall into ill health and dysfunction. Because of the intimate relationship between the nervous system and vertebra, there is ample opportunity for a nerve to get pinched or irritated, creating symptoms and imbalance somewhere in the body.

It is crucial for each vertebra to be in it's proper position for normal functioning of the nervous system. A misalignment may interrupt the normal transmission of nerve impulses to any part of the body. Certain parts of the body may end up not getting enough blood and nerve supply, affecting the health of vital organs and tissue. Anatomy and physiology teach us that the normal, healthy performance of all the body's operations requires uninterrupted nerve and blood flow from the brain, spinal cord and organs.

Training & Education
  • Chiropractic institutions only accept students who have completed a pre-chiropractic program of at least two years. The required courses for the pre-chiropractic education are concentrated in the sciences, similar to a pre-medical school curriculum.
  • Many students enter chiropractic study with an undergraduate degree in the sciences. After completing the pre-chiropractic requirements, students must complete at least four years of academic study in an accredited chiropractic institution to graduate.
  • To practice, the graduate must pass extremely demanding national and state board exams.
