Anatomy of the Spine
Structure and Purpose of the Human Spine
The human spine is an amazing and intricate structure combining strength, stability, and flexibility.
No matter what position you’re in—whether you’re sitting, standing, or even sleeping—your spine is always working hard to support your body and adapt to the physical demands placed on it. It plays a vital role in keeping you moving and feeling balanced.
Key Functions of the Human Spine
In a healthy adult, the spine is naturally balanced over the pelvis, allowing the muscles to work less to keep you standing tall. However, when that balance is off, the spinal muscles have to work harder, leading to strain and even changes in the spine’s shape as it keeps you upright.
Protects some of the body’s most essential parts, like the spinal cord, nerve roots, and internal organs.
Allows us to move freely and easily and bend, twist, and turn easily.
Provides the support we need to stand tall and stay balanced.
Carries the weight of the head, shoulders, arms, and upper body, distributing that weight to the hips and legs.
Helps reduce the strain on our muscles, making it easier to stay upright without feeling muscle fatigue or back pain.
