Did you know that you have twelve (12) pairs of ribs; seven of which connect your spine to your sternum (breastbone)?
The primary function of the ribcage is to house and protect the heart and lungs and associated vital structures while allowing movement for breathing (chest expansion). The ribheads (ends) are attached to the first seven thoracic vertebrae in the back (spine), and to the sternum in the front. Ribs are mostly bone, but transition to a more pliable (bendable) cartilage material as they approach the sternum. The purpose of this is to allow some degree of movement during breathing.
The diaphragm is a thin, umbrella-shaped muscle underneath the lungs that allows you to inhale and exhale. When you inhale, your diaphragm lowers, or drops downward, which creates a bellows-like effect on the lungs, causing a negative pressure that draws in air. When you exhale, you are effectively relaxing the diaphragm, letting it rise to its neutral position. All the while, the ribcage, if working properly, pivots slightly at the rib attachments to allow full lung movement.
However, ribs can get subluxated, or shift out of their normal articulation with the vertebrae and/or sternum. This can be from trauma, like a car accident or sports injury; poor posture, and repetitive movements like golf swinging. If the subluxation is bad enough, you can feel a focal, sharp pain on the affected side of the spine when taking in a deep breath. Other times, the subluxation is very subtle and doesn't hurt, but it inhibits proper rib expansion. It can be with you for years, undetected. The only thing you may notice is tiredness from not getting enough oxygen in each breath due to inhibited ribcage (thus, lung) expansion; or, your may find that you can twist your torso to one side more than the other side.
Chiropractic adjustments to the ribheads, rib angles, and sternum can help correct rib subluxations. It's just another way chiropractic can help your body function more efficiently. If you are experiencing any of the symptoms mentioned here, you may want to have your ribcage assessed for proper movement.
