When a disk herniates, the nucleus pulposus, which is the gel-like core of the intervertebral disk, typically extrudes through the annulus fibrosus, the fibrous outer layer of the disk. This extrusion can lead to compression of nearby structures, particularly nerve roots that exit the spinal column. The herniated material may invade the space through which these nerve roots travel, potentially causing pain, numbness, or weakness in the areas controlled by those nerves. This mechanical compression is often the primary cause of the symptoms associated with herniated disks, making the understanding of this process crucial in recognizing how herniation affects neurological functions.
