ANNULUS FIBROSUS Meaning and Definition

1. The annulus fibrosus is a part of the intervertebral disc located between the vertebrae of the spinal column. It is a fibrous ring-like structure that surrounds and provides support to the nucleus pulposus, the gel-like center of the disc.

   Composed mainly of concentric layers of fibrocartilage, the annulus fibrosus is instrumental in distributing loads and absorbing shock throughout the spine. Its primary function is to maintain the shape and integrity of the intervertebral disc, ensuring stability and flexibility in the spinal column.

   The annulus fibrosus consists of collagen fibers arranged in a crisscross pattern, providing strength and resistance to various types of mechanical stress. It is thicker and more densely packed on its outer edges, known as the peripheral annulus, to enhance stability and withstand shear forces. In contrast, the central annulus, located closer to the nucleus pulposus, contains less collagen and is more elastic, allowing for movement and flexibility.

   When the annulus fibrosus becomes damaged or weakened, such as through degenerative changes or trauma, it can lead to conditions like disc herniation or bulging discs. These conditions occur when the nucleus pulposus protrudes through fissures or tears in the annulus fibrosus, potentially causing pressure on spinal nerves and subsequent pain or other neurological symptoms.

   Overall, the annulus fibrosus is a vital component of the intervertebral disc, providing strength, support, and resilience for proper spinal function.

2. One of two fibrous rings surrounding the atrioventricular orifices, circulus callosus Halleri.
