Pankadevahelised

Pankadevahelised, also known as intervertebral discs, are fibrocartilaginous structures located between the vertebrae of the spine. They serve several crucial functions, including cushioning the vertebrae, absorbing shock, and facilitating movement. Each disc consists of two main components: the annulus fibrosus, a fibrous outer ring, and the nucleus pulposus, a gel-like inner core. The annulus fibrosus provides structural support and prevents the nucleus pulposus from herniating, while the nucleus pulposus acts as a shock absorber and nutrient distributor.

Intervertebral discs are essential for maintaining the flexibility and mobility of the spine. They allow for a range of motion, including flexion, extension, rotation, and lateral bending. Additionally, the discs contribute to the spine's ability to withstand compression and shear forces, which are common during physical activities and daily movements.

However, intervertebral discs can also be a source of pain and discomfort, particularly in conditions such as herniated discs, degenerative disc disease, and spinal stenosis. These conditions can result from age-related wear and tear, trauma, or other factors that compromise the integrity of the discs. Treatment options may include rest, physical therapy, medications, or, in severe cases, surgical intervention.

In summary, pankadevahelised play a vital role in the structure and function of the spine, providing support, cushioning, and mobility. Understanding their anatomy and function is crucial for diagnosing and managing spinal disorders.
