Cartilage in the spinal column primarily facilitates smooth movement and provides cushioning between vertebrae, especially within the facet joints.
Here's a more detailed breakdown:
-
Smooth Articulation: Cartilage is a slippery connective tissue. This allows the vertebrae to slide against each other smoothly at the facet joints. The facet joints are crucial for flexibility and stability, enabling twisting and turning motions. Without cartilage, bone would rub directly on bone, causing pain and restricted movement.
-
Shock Absorption: Cartilage, particularly in the intervertebral discs, acts as a shock absorber. The intervertebral discs contain a specialized type of cartilage. This cushions the vertebrae during activities such as walking, running, and jumping, preventing damage to the bones and spinal cord.
-
Reduced Friction: Cartilage minimizes friction between bony surfaces. This reduces wear and tear on the vertebrae and helps to maintain the long-term health of the spinal column.
In essence, cartilage is essential for the proper function, flexibility, and protection of the spinal column.
