Your lumbar disc is not a donut

Intervertebral discs are situated between each vertebra from C2-C3 to L5-S1, and together they constitute about one-fourth of the spine's total height. These discs function as shock absorbers for the forces exerted on the spine and enable spinal movement.

While movement at any individual disc is limited, the combined action of all the vertebrae and discs allows for a substantial range of motion. Each intervertebral disc consists of two parts: the annulus fibrosus and the nucleus pulposus. The annulus fibrosus, the disc's outer layer, is made up of concentric layers of collagen and proteins known as lamellae.

Intervertebral discs are incredibly strong, designed to handle significant compressive forces, which makes them effective shock absorbers for the spine. The annulus fibrosus, the tough outer layer, is made of multiple layers of collagen fibers arranged in a crisscross pattern, providing strength and resistance to torsion (twisting) and shear forces. This structure helps prevent the disc from tearing under normal movement and loads.

The nucleus pulposus, the inner gel-like core, allows the disc to distribute pressure evenly when the spine is subjected to compressive forces, such as when lifting or jumping. This combination allows the discs to withstand both high levels of stress and strain while maintaining spinal flexibility. However, despite their strength, intervertebral discs can be vulnerable to degeneration or injury over time, particularly with heavy or repetitive loads or due to aging.
