Cervical Herniated Disc Herniated disc, commonly known as a slipped disc, is a condition in which the central part of the intervertebral disc protrudes into the spinal canal. This typically occurs due to a tear in the tough fibrous annular ring that surrounds a soft inner core, resulting in herniation of the softer material.

- 1 The most common location for a herniated disc to occur is in the disc at the level between the fourth and fifth lumbar vertebrae in the low back. 2  If the disc herniation is large enough, the disc tissue can press on the adjacent spinal nerves that exit the spine at the level of the disc herniation.

Herniated Disk This can lead to pain, numbness, or weakness. The lower back (lumbar area) of the spine is the most common area affected by a slipped disk. The neck (cervical) disks are the second most commonly affected area. The upper-to-mid-back (thoracic) disks are rarely involved. A herniated disk is one cause of radiculopathy.

Spinal Arthritis What is a herniated disc? A herniated disc is a disc that extrudes into the spinal canal. It is also referred to as a bulging disc, ruptured disc or slipped disc. As a disc degenerates, it can herniate (the inner core extrudes) back into the spinal canal, as shown in this picture on the right. The light blue oval area is the disc, and it is bulging into the spinal canal on the lower right side of the disc. A lumbar herniated disc can cause pain to radiate all the way down the legs and into the foot. In the area of the cervical spine, the pain would radiate from the neck, down the arm and into the fingers.

- Introduction. A slipped disc – known as a prolapsed or herniated disc – occurs when one of the discs that sit between the bones of the spine (the vertebrae) is damaged and presses on the nerves.This can cause back pain and neck pain, as well as symptoms such as numbness, a tingling sensation, or weakness in other areas of the body.he damaged disc can put pressure on the whole spinal cord or on a single nerve root (where a nerve leaves the spinal cord). This means a slipped disc can cause pain both in the area of the protruding disc and in the area of the body controlled by the nerve that the disc is pressing on.

Cervical Disc Herniation - Topic Overview If they become damaged, they may bulge abnormally or break open (rupture), in what is called a herniated or slipped disc. Herniated discs can occur in any part of the spine, but they are most common in the neck (cervical) and lower back (lumbar) spine. The seven vertebrae between the head and the chest make up the cervical spine. What causes cervical disc herniation? A herniated disc usually is caused by wear and tear of the disc (also called disc degeneration).

- Herniated disk is a medical condition in which the gel like disk between the bones of the spine squeezes out of its center position. Because nerves run in the spine right next to the disk, a herniated disk can compress a nerve and cause symptoms such as low back pain, numbness and tingling. ...Read more.

Lumbar Disc Herniation: General Information? In Figure 1.75, is a T2-weighted sagittal MRI image through the lumbar spine that demonstrates a rare type of disc herniation called a sequestration. A sequestration occurs when a fragment of herniation (red arrows) breaks off from the main disc extrusion (green arrows) and is free to travel within the epidural space.

Herniated disc â herniated disc in the thoracic spine While a herniated disc usually occurs in the cervical spine (neck) or lumbar spine (lower back), it can occasionally present itself in the thoracic spine (middle back). A thoracic herniated disc often presents symptoms of pain in the back and in one of the extremities, depending on the location of the herniated disc. For example, if the herniated disc is in the upper part of the thoracic spine, you may experience pain in one of your arms or hands.

Calculus AB: Applications of the Derivative page 1 of 3. First, let's establish some definitions: f is said to be increasing on an interval I if for all x in I, whenever. f is said to be decreasing on an interval I if for all x in I, whenever. A function is monotonic on an interval I if it is only increasing or only decreasing on I. The derivative can help us determine whether a function is increasing or decreasing on an interval. This knowledge will later allow us to sketch rough graphs of functions. Let f be continuous on [a, b] and differentiable on (a, b) . If for all x on (a, b) , then f is increasing on [a, b] . If for all x on (a, b) , then f is decreasing on [a, b] . This should make intuitive sense. In the graph below, wherever the slope of the tangent is positive, the function seems to be increasing.

Disc Herniations in the Lumbar Spine: Frequently Asked Questions Disc herniation is a broad term describing specific changes in a lumbar disc. First, the disc itself needs to be addressed. A disc is the structure between the lumbar vertebral bodies (bones). The disc acts as a pad or cushion for the bone. The outer portion of the disc is made up of a tough fibro-cartilage matrix (the annulus) that is cross-linked in three different directions.

- A herniated lumbar disc is a condition in which there is protrusion of the. intervertebral disc. Herniations occur most commonly through a posterolateral defect, but midline herniations may occur. Resulting compression of the spinal nerve root causes. inflammation and pain, often along the anatomic course of the nerve.

Lumbar Herniated Disc Lumbar Herniated Disc. Lumbar discs are the cushions between the vertebrae in the back. Herniation of the disc occurs when the gelatinous inner disc material, the nucleus pulpous, ruptures, or herniates, through the outer lumbar disc wall.he immediate precipitating cause of the lumbar herniation can be varied. This can be excessive stress being placed on the disc, whether as a result of heavy lifting or other damaging motions. Pain and other symptoms can develop when the damaged disc pushes into the spinal canal or nerve roots.

Herniated Disc Located between each of the vertebra in the spinal column, discs act as shock absorbers for the spinal bones. A herniated disc (also called a bulged, slipped or ruptured) disc is a fragment of the disc nucleus that is pushed out of the annulus, into the spinal canal through a tear or rupture in the annulus.

Cervical (neck) herniated disc â overview, causes and treatment options Causes of cervical herniated discs. A herniated disc is caused by severe compression in the spine, usually due to general wear and tear or injury. Usually, a herniated disc will either occur in the cervical spine (neck) or lumbar spine (lower back) due to the natural degeneration of the spine over time. The cervical spine is responsible for supporting and stabilizing the head and neck, as well as allowing movement at the pivot point between the head and neck.

Herniated cervical disc A herniated disc is a spine condition that occurs when the gel-like center of a disc ruptures through a weak area in the tough outer wall, similar to the filling being squeezed out of a jelly doughnut.Neck or arm pain may result when the disc material touches or compresses a nearby spinal nerve. herniated disc occurs when the gel-like center of your disc ruptures out through a tear in the tough disc wall (annulus) (Fig. 1). The gel material is irritating to your spinal nerves, causing something like a chemical irritation.
