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. … They also provide a shock-absorbing effect within the spine and prevent the vertebrae from grinding together.
What are the 3 functions of our intervertebral discs?
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.
Where are intervertebral discs?
Intervertebral discs are located between each vertebra from C2-C3 to L5-S1. Combined, they make up one fourth the height of the spinal column. The discs act as shock absorbers to the loads placed on the spine and allow movement of the spine.
What can cause damage to the intervertebral discs?
- Slipped disc (prolapsed disc).
- Degenerative disc disease. As we get older the spinal discs become damaged and weaker (degenerate).
- Infection of the spinal disc (discitis). The infection is usually caused by a germ (bacterium) but is sometimes caused by a viral infection.
How do intervertebral discs work?
An intervertebral disk acts as shock absorber between each of the vertebrae in the spinal column by keeping the vertebrae separated when there is impact from activity. They also serve to protect the nerves that run down the middle of the spine and intervertebral disks.
What are the two main roles of intervertebral discs?
The intervertebral discs have the following functions: They provide cushioning for the vertebrae and reduce the stress caused by impact. By keeping the vertebrae separated from each other, they act as a type of shock absorber for the spine. They help protect the nerves that run down the spine and between the vertebrae.
What happens to the intervertebral disc as we age?
The discs between the bones of the spine are made up of cartilage, fibrous tissue, and water. With age, these discs can weaken and may flatten, bulge, or break down.
Is spondylolisthesis a disease?
Spondylolisthesis is a spinal condition that affects the lower vertebrae (spinal bones). This disease causes one of the lower vertebrae to slip forward onto the bone directly beneath it. It’s a painful condition but treatable in most cases.
Is the intervertebral disc a synovial joint?
The structural classification of the intervertebral disc joint is a fused, fibrocartilaginous symphysis. However, functionally, it is considered an amphiarthrosis which permits a limited amount of movement. … The zygapophyseal joint is structurally classified as a plane synovial joint.
What is lumbosacral intervertebral disc?
The lumbar spine is composed of motion segments. Each motion segment consists of two vertebral bodies, the intervertebral disc, and two facet joints. The intervertebral disc acts as the cushion, or “shock absorber,” of the spine. The intervertebral disc is made up mostly of water.
What is intervertebral disc displacement?
Disc herniation (termed as intervertebral disc displacement) is a type of spinal disease based on IDD or not, with local pain and/or sciatica due to mechanical compression and autoimmune cascades upon the corresponding nerve roots.
Is intervertebral disc cartilage?
The intervertebral disc is a cartilaginous structure that resembles articular cartilage in its biochemistry, but morphologically it is clearly different. It shows degenerative and ageing changes earlier than does any other connective tissue in the body.
What are the symptoms of disc problem?

Do intervertebral discs have nerves?
The lumbar intervertebral discs are supplied by a variety of nerves. The posterior aspects of the discs and the posterior longitudinal ligament are innervated by the sinuvertebral nerves. … The anterior longitudinal ligament is innervated by recurrent branches of rami communicantes.
How do intervertebral discs get nutrients?
The disc is avascular, and the disc cells depend on diffusion from blood vessels at the disc’s margins to supply the nutrients essential for cellular activity and viability and to remove metabolic wastes such as lactic acid.
What prevents hyperextension of the spine?
There are two longitudinal ligaments that run vertically along the anterior and posterior aspect of the body of the vertebrae. The anterior longitudinal ligament attaches to both the vertebra and the intervertebral discs. This ligament helps to prevent hyperextensions of the spine.
What is the cauda?
Cauda is Latin for tail, and equina is Latin for horse (ie, the “horse’s tail”). The CE provides sensory innervation to the saddle area, motor innervation to the sphincters, and parasympathetic innervation to the bladder and lower bowel (ie, from the left splenic flexure to the rectum).
Is lumbar spondylosis arthritis?
Technically, spondylosis is a form of arthritis—spinal osteoarthritis (osteoarthritis is the most common type of arthritis) to be exact. We tend to think of arthritis as something you get in your hands and knees, but the spine, and all of its bones and joints, can fall victim to its grip as well.
How can I prevent degenerative disc disease from getting worse?

Is mild disc degeneration normal?
Spinal disks wear down as a normal part of aging. Especially after age 40, most people experience some disk degeneration. However, not everyone experiences pain.
Can you reverse spine degeneration?
While disc degeneration can’t be reversed, there is evidence that exercise, lifestyle changes and careful management of your back pain can contribute to better quality of life.
What is a Grade 1 spondylolisthesis?
One commonly used description grades spondylolisthesis, with grade 1 being least advanced, and grade 5 being most advanced. The spondylolisthesis is graded by measuring how much of a vertebral body has slipped forward over the body beneath it. Grade 1. 25% of vertebral body has slipped forward.
What does spondylolisthesis pain feel like?
Patients with degenerative spondylolisthesis will often develop leg and/or lower back pain when slippage of the vertebrae begins to put pressure on the spinal nerves. The most common symptoms in the legs include a feeling of diffuse weakness associated with prolonged standing or walking.
Is spondylolisthesis serious?
Spondylolisthesis is a common cause of back pain, but it is not dangerous and doesn’t need to take over your life. Many treatments are available, from medication and physical therapy to spinal surgery.
What bones are involved in the intervertebral joint?
The meeting points of the upper and lower spinal bones that comprise an intervertebral joint are the vertebral body in front and the vertebral arch in the back.
Which joints are Diarthrotic?
Diarthrosis. A freely mobile joint is classified as a diarthrosis. These types of joints include all synovial joints of the body, which provide the majority of body movements. Most diarthrotic joints are found in the appendicular skeleton and thus give the limbs a wide range of motion.
Are intervertebral joints Diarthrotic?
An example is the manubriosternal joint or the joints between the skull bones surrounding the brain. An amphiarthrosis is a slightly moveable joint, such as the pubic symphysis or an intervertebral cartilaginous joint. A diarthrosis is a freely moveable joint.

Is intervertebral disc connective tissue?
Fibrocartilage is a mixture of dense regular connective tissue and hyaline cartilage. It is found in intervertebral discs, pubic symphysis, articular discs and menisci of joints. They have a fibrous appearance of mostly collagen fibers with interspersed areas of cartilage. …
How does a herniated disc cause back pain?
Discs that become herniated usually are in an early stage of degeneration. The spinal canal has limited space, which is inadequate for the spinal nerve and the displaced herniated disc fragment. Due to this displacement, the disc presses on spinal nerves, often producing pain, which may be severe.
What type of tissue is the intervertebral disc?
2.1 Introduction. Intervertebral discs are pads of fibrocartilage which lie between the vertebrae of the spine. Age-related changes are particularly severe in intervertebral discs because they are the largest avascular structures in the human body, and have a low capacity for regeneration and repair.
Can disc problem be cured?
Yes, slipped disc can be cured. It cannot be entirely prevented but one can reduce the risk by being physically active, performing back strengthening exercises and yoga. But in case if someone already has a severe back problem, he/she can get operated and get back to their normal life in some time, tells Dr Manu Bora.
What happens when disc is gone?
When the disc breaks down in the lower spine, it can lead to can lead to lower back pain, leg pain and other symptoms such as numbness and weakness. In the neck, a problem with a disc can lead to pain and symptoms in the neck, shoulder, arm and possibly into the hand.
How do you know if its muscle or disc pain?
While pain in your mid-back may be related to a disc, it’s more likely caused by muscle strain or other issues. Your symptoms feel worse when you bend or straighten up from a bent position. Movement can increase pressure on the herniated disc and the surrounding nerves, causing symptoms to increase.
