lülivaheketta

Lülivaheketas, also known as an intervertebral disc, is a crucial component of the human spine. It is a soft, cushion-like structure that sits between adjacent vertebrae, acting as a shock absorber and allowing for movement. Each disc consists of two main parts: the annulus fibrosus, a tough outer layer of cartilage, and the nucleus pulposus, a jelly-like inner core. This composition allows the disc to withstand significant pressure and maintain flexibility.

The primary function of lülivaheketas is to absorb the impact and stress placed on the spine during everyday activities such as walking, running, and lifting. They also permit movement between the vertebrae, enabling us to bend, twist, and rotate. Without these discs, the vertebrae would rub directly against each other, causing pain and limiting mobility.

Degeneration or injury to the lülivaheketas can lead to various spinal conditions. A common issue is a herniated disc, where the nucleus pulposus protrudes through a tear in the annulus fibrosus, potentially pressing on nearby nerves and causing pain, numbness, or weakness. Other problems include disc desiccation, where the disc loses water content and becomes less effective as a shock absorber, and discitis, an inflammation of the disc. Maintaining good posture and avoiding excessive strain on the spine can help preserve the health of these vital structures.
