Intervertebral Disk:
An intervertebral disk is a round, flat, gel-like structure found between the individual vertebrae in the spine. It serves as a shock absorber and cushion between the bones, allowing for flexibility and movement of the spine.
Each intervertebral disk consists of two main parts: the annulus fibrosus and the nucleus pulposus. The annulus fibrosus is the outer layer of the disk, made up of tough, fibrous cartilage. It surrounds and encases the nucleus pulposus, providing structural support and preventing it from bulging outwards. The annulus fibrosus also contains nerves, which can become irritated or damaged if the disk is injured or degenerated.
The nucleus pulposus is the inner portion of the intervertebral disk. It is a gel-like substance that is primarily composed of water and proteoglycans. This gel-like composition enables the nucleus pulposus to absorb and distribute pressure evenly across the disk, making it resistant to compression forces and providing shock absorption during everyday activities, such as walking, running, and jumping.
Overall, the intervertebral disk plays a vital role in maintaining the structural integrity and function of the spine. It helps to absorb shocks and loads, allowing for movement and protection of the spinal cord and nerves. However, these disks can be subject to wear and tear over time, leading to conditions such as herniated or degenerative discs, which may cause pain and discomfort in the back or neck.

Etymology of INTERVERTEBRAL DISK
The word "intervertebral disk" has its roots in Latin and Greek.
The term "intervertebral" comes from Latin, with "inter" meaning "between" and "vertebra" meaning "joint" or "spinal bone". So, "intervertebral" refers to something that is located between the vertebrae.
The word "disk" has Greek origins. It is derived from the Greek word "diskos", which means "disk" or "circular plate". This term was often used in ancient Greek literature to describe round, flat objects.
Therefore, the combination of "intervertebral" and "disk" forms the term "intervertebral disk", which refers to the circular, fibrocartilaginous structure located between the vertebrae in the spine.
