The Backbone of Your Life: A Beginner’s Guide to Spinal Anatomy
Your spine is more than just a stack of bones—it’s your body’s communication superhighway, structural support system, and shock absorber all in one. At Limitless Chiropractic here in Wellington, we often say: when your spine works well, life flows better. And that’s not just a catchy phrase—it’s rooted in science.
Understanding basic spinal anatomy is key to knowing how your body moves, how your nervous system functions, and why taking care of your spine pays off in energy, performance, and quality of life.
The Spinal Structure: Not Just a Column, But a Complex Network
Your spine is made up of 33 vertebrae, divided into five regions:
- Cervical Spine (Neck) – 7 vertebrae: This region supports your head and allows for movement like nodding and rotation. It also houses the delicate nerves that branch to your arms and hands.
- Thoracic Spine (Upper Back) – 12 vertebrae: These vertebrae connect to your ribs and protect your heart and lungs. While they have less mobility, they’re vital for stability.
- Lumbar Spine (Lower Back) – 5 vertebrae: These bear the bulk of your body’s weight and allow for powerful movement like lifting and bending.
- Sacrum – 5 fused vertebrae: This triangular section connects the spine to the pelvis, distributing weight through the hips and legs.
- Coccyx (Tailbone) – 4 fused vertebrae: A small yet crucial anchor point for ligaments and muscles of the pelvic floor.
Each vertebra is separated by a disc—a cushiony structure that acts like a shock absorber, enabling movement while protecting the bones and nerves.
The Nervous System Connection
Running through the centre of your spine is the spinal cord, part of your central nervous system. It carries messages from your brain to your entire body—and back again. Tiny nerve roots branch off at each vertebral level and control everything from your breathing and digestion to muscle strength and coordination.
This is why at our Wellington chiropractic clinic, we don’t just treat sore backs—we help restore communication between your brain and body by improving how your spine moves and functions.
Motion Matters: Why Spinal Movement Is Key
When the joints in your spine stop moving properly—what we call joint dysfunction or a loss of proper motion—it doesn’t just feel stiff or sore. It can disrupt nerve flow, reduce mobility, cause muscle imbalances, and even affect your mood or energy levels.
One study published in NeuroImage showed that spinal adjustments could positively impact brain function by altering prefrontal cortex activity—meaning better focus, movement control, and even emotional regulation (Lelic et al., 2016).
What You Can Do
A healthy spine needs movement, strength, and alignment. Try this simple daily habit:
- On all fours, inhale as you arch your spine (cow), lifting your head and tailbone.
- Exhale as you round your spine (cat), tucking chin and pelvis.
Repeat for 60 seconds to wake up your spinal segments.
And if you’re noticing any recurring tension, limited motion, or unusual fatigue—it could be time for a professional spinal check-up.
