Spinal Structures

The spinal column is an intricate framework of interlocking bones that, when viewed from the side, form a gentle "S" shape. The spine is a sophisticated system-both fragile and sturdy-of muscles, bones, joints, ligaments, discs, a spinal cord, and nerves.

Joints, called "facet joints," and discs allow the spine to bend and twist and absorb mild shocks and bumps. The brain, spinal cord and nerves manage your body's movement by sending messages to muscles. Supporting the entire structure is an intricate system of ligaments, tendons, and discs.

The vertebrae, facet joints and discs are vertically stacked in a healthy spine. Ligaments support that alignment and discs, which are flexible, spongy pads, absorb shocks between the vertebrae and joints.

The spine has four natural curves, which help to evenly distribute the loads incurred by daily activity-from sitting, walking and running, to lifting and carrying.

There are three major parts of your spine:

  • The cervical spine, or neck
  • The thoracic spine, or upper back
  • The lumbar spine, or lower back

The sacrum, which lies at the base of your spine between the fifth lumbar and the tailbone, or coccyx, is a triangular-shaped bone made up of five fused parts. These are called "S1, S2, S3, S4 and S5." These unique parts connect to your pelvis by way of structures called sacroiliac joints.

Your neck, which is also called the upper cervical spine, is distinguished by two large vertebrae. One is called the upper bone, or atlas, and the other is called the lower bone, or axis.

These bones in your cervical spine do not need discs and protect the medulla oblongata, or lower brainstem. Inside the medulla oblongata are reflex centers that regulate such things as your heartbeat, breathing, the diameter of your blood vessels, swallowing, vomiting, coughing, sneezing, and hiccupping.

Almost half your brain's 12 cranial nerves originate in the medulla and control such things as balance and hearing, taste, swallowing, salivation, the digestive system, head and neck muscles and the tongue. One can easily see that if the upper bones of your spinal cord are out of alignment, a whole host of things can go wrong in your body, some subtle, some not-so-subtle. However, it is not uncommon for many of us to have some sort of misalignment in these structures, as we go through the daily trials and tribulations of life.

Basically, your spine is composed of four types of material. These are:

  • Vertebral bodies - These are the large bony structures you see in the spinal anatomy and essentially are the support column of your back. This amazing structure supports about half of your body's weight; your muscles do the job of the remaining half. Vertebral bodies are separated by small spaces containing discs. Most of the vertebral bodies in your spine have several joints that allow your back to bend and flex. When you bend forward, your hips provide about half of the impact, while your lower spine, or lumbar, takes on the rest.
  • Vertebral discs - The shock absorbers that are found between vertebral bodies, discs are essentially made up of two major parts: a tough outer core and a soft inner core. When you are born, these discs are mostly water. As you get older, the discs slowly lose their water content and get harder. As they dehydrate over time, your discs provide less of that soft and cushy support they provided when they were new. Because they have no blood supply and few nerve endings, discs are unable to repair themselves. Disc degeneration can be painful in later years; in some cases, the inner core of the discs leak proteins that can inflame the nerve roots.
  • Spinal cord and nerve roots - As it leaves the base of your brain, your spinal cord weaves through the neck and upper back, ending up at the bottom of your thoracic spine. Actually, your spine ends before it reaches your lower back, shooting off a series of nerve roots that are dispersed through bony canals throughout your body.
  • Muscles - The soft tissue surrounding your spine is largely composed of muscles, which support your spine as it bends and flexes. Two large muscles in your lower back, called erector spinae, help hold up the spine.

What Our Clients Say About Us

  • "My initial reason for seeking chiropractic care was because I was having some back, neck, and shoulder problems. I had seen other chiropractors and achieved no results. This was not the case at The Body Connection. The experience here is very educational in learning how the body works. I am now able to function in a lot less pain. As a result, I am now more active and look at life with more understanding on how to stay healthy."
    Maria H.
  • "I first encountered The Body Connection through Groupon when I came in for a massage. I had a conversation with Dr. Logan and as a result of being treated here, I am now able to do intense workouts, boot camp, and boxing. I have also experienced increased weight loss and now have better posture. Dr. Logan and her staff have been very supportive."
    Lora K.
  • "I have been treated by other chiropractors in the past and over the years coming to The Body Connection has been a wonderful experience. I initially came in for lower back and hip pain. As of now, my flexibility has improved and my pain has diminished. I can now walk and stand for longer periods of time. Also doing daily house work isn’t as painful. I feel better after being treated by the doctor. My energy level is increased and it also improves my state of mind."
    Laura C.
  • "After the awesome massage I enjoyed, I decided to have a consultation with Dr. Logan who encouraged me and stated she could help me. I can now hold my head up better and my chronic headache syndrome has subsided. My experience at The Body Connection has been marvelous. To say it plainly; I just feel better!"
    Maura M.
  • "Prior to meeting the staff of The Body Connection Health and Wellness Center at a Ladies Day Expo, I had no knowledge of chiropractic care. Dr. Logan educated me on how the different issues I was experiencing were connected. As a result of getting treated at this facility, my body feels better. I am now able to sit and ride in a car without feeling the lower back pain and spasms of the past."
