What is the intervertebral disc?

What is the intervertebral disc?

The intervertebral discs provide cushioning between vertebrae and absorb pressure put on the spine. While the discs in the lower (lumbar ) region of the spine are most often affected in intervertebral disc disease, any part of the spine can have disc degeneration.

What is the intervertebral disc made of?

The intervertebral disc is made up of two components: the annulus fibrosus and thenucleus pulposus. The annulus fibrosus is the outer portion of the disc. It is composed of layers of collagen and proteins, called lamellae.

Is intervertebral discs made of fibrocartilage?

The intervertebral disc (IVD) is important in the normal functioning of the spine. It is a cushion of fibrocartilage and the principal joint between two vertebrae in the spinal column.

Is intervertebral disc a joint?

An intervertebral disc (or intervertebral fibrocartilage) lies between adjacent vertebrae in the vertebral column. Each disc forms a fibrocartilaginous joint (a symphysis), to allow slight movement of the vertebrae, to act as a ligament to hold the vertebrae together, and to function as a shock absorber for the spine.

Which intervertebral disc is largest?

The intervertebral discs are largest and thickest in the lumbar region, because these vertebrae carry the bulk of the body’s weight. The discs are thinnest in the upper thoracic region.

Which position puts the least pressure on the spine?

And while it may seem a bit counterintuitive, sitting down to “take a load off” can actually add quite a bit of pressure to our backs. When our back is in its ideal position, with us standing straight up or lying flat, we’re placing the least amount of pressure on the discs between vertebrae.

Which intervertebral disc is smallest?

The intervertebral discs are largest and thickest in the lumbar region, because these vertebrae carry the bulk of the body’s weight. The discs are thinnest in the upper thoracic region. Intervertebral discs are made up of 2 parts.

What position puts the most pressure on your spine?

Sitting is becoming more prevalent while at work, and having a sedentary desk job can result in sitting for around 8 hours a day. This position actually increases the load on your spine more than standing. Spinal pressure “sits” around 140mm pressure.

How should you sleep when you have degenerative disc disease?

Degenerative disc disease Sleeping on the stomach is typically preferred, as this position can relieve pressure on the disc space. People with degenerative disc disease may feel most comfortable using a relatively firm mattress while placing a flat pillow under the stomach and hips.

What are intervertebral discs are an example of?

Intervertebral discs are made of fibrocartilage and thereby structurally form a symphysis type of cartilaginous joint. An amphiarthrosis is a joint that has limited mobility. An example of this type of joint is the cartilaginous joint that unites the bodies of adjacent vertebrae.

Which intervertebral disc is the largest?

This is due to the difference in thickness between the front and back parts of the intervertebral discs. The lumbar vertebrae are located between the ribcage and the pelvis and are the largest of the vertebrae. The pedicles are strong, as are the laminae, and the spinous process is thick and broad.

What do intervertebral disc consists of?

An intervertebral disc consists of three main parts: Annulus fibrosis. The disc’s exterior is made up of concentric rings of collagen that twist and bend as the spine moves. Nucleus pulposus. The disc’s interior is a gel-like mixture of water and proteins that provides cushioning between vertebral bodies. Cartilaginous endplates. Between the disc and each vertebral body is an endplate made of cartilage that connects the disc to the vertebrae and acts as a gatekeeper, controlling the flow

What are the symptoms of intervertebral disc syndrome?

Symptoms of Intervertebral disc disease. The list of signs and symptoms mentioned in various sources for Intervertebral disc disease includes the 9 symptoms listed below: Back pain. Neck pain. Herniated disc. Compressed disc. Leg pain.
