Vahelüli

Vahelüli is an Estonian word that translates to "intervertebral disc" in English. These are crucial components of the human spine, located between each vertebra. They act as shock absorbers, cushioning the bones of the spine during movement and preventing them from grinding against each other. Each vahelüli consists of two main parts: the annulus fibrosus, a tough outer ring of fibrous cartilage, and the nucleus pulposus, a soft, gel-like center. This structure allows for flexibility and movement in the spine while also providing stability.

The health of vahelüli is vital for spinal function. Over time, or due to injury or degenerative processes, these discs can be damaged. Common issues include herniation, where the inner nucleus pulposus pushes through the outer annulus fibrosus, potentially pressing on nerves and causing pain. Degeneration, often associated with aging, can cause the discs to lose their height and water content, leading to reduced cushioning and stiffness. Maintaining good posture, regular exercise, and a healthy weight can help promote the health of vahelüli and prevent issues.
