Spondylosis (degeneration) of the c5-c6 vertebrae and intervertebral disc occurs at a higher rate compared to other cervical vertebrae. 3 spondylosis usually results in the formation of bone spurs (osteophytes), eventually leading to stenosis or narrowing of the intervertebral foramina or spinal canal.

Disc herniation into the intervertebral foramen (ivf) or osteophytic outgrowths from the margins of the apophyseal joints that project into the ivf may compress the neural structures, but in this cadaveric study of 160 lumbar foramens (age range, 35-91 years), the authors have found that they were much more commonly associated with compression and distortion of the large venous plexus within.
The vertebral foramen provides for passage of the spinal cord. Each spinal nerve exits through an intervertebral foramen, located between adjacent vertebrae.
The nerve roots pass out of the spinal canal through the intervertebral foramen, where they feed the body either anteriorly (motor) or posteriorly (sensory). The anterior divisions supply the front of the spine including the limbs. The posterior divisions are distributed to the muscles behind the spine.
Nerves pass through the intervertebral foramina the transverse foramen lies in the transverse process of the upper six vertebrae and provides a channel for the vertebral artery, vertebral vein, and sympathetic nerves.

In total, the intervertebral discs account for approximately 25 percent of your body height between the top of the pelvis and the base of the skull. Intervertebral discs are also flexible and can change shape to allow for movements of the vertebral column.
The ventral and dorsal roots fuse together to form a spinal nerve, which travels down the spinal canal, alongside the cord, until it reaches its exit hole - the intervertebral foramen (fig. Once the nerve passes through the intervertebral foramen, it branches; each branch has both motor and sensory fibers.
The intervertebral foramen (also called neural foramen, and often abbreviated as iv foramen or ivf), is a foramen between two spinal vertebrae. Cervical, thoracic, and lumbar vertebrae all have intervertebral foramina. The foramina, or openings, are present between every pair of vertebrae in these areas.
The pedicles and laminae on either side form the neural arch which together with the posterior surface of the body enclose the vertebral foramen. The pedicles are notched on their superior and inferior surfaces, in the articulated thoracic spine, these notches form the intervertebral foramina for the passage of the thoracic spinal nerves.
L5-s1-there are end plate entophytes and there is bilateral facet osteoarthritis. There is mild narrowing of the intervertebral foramina bilaterally and there is a mild bulging of the disc. L2-l3-there is a right far lateral disc extrusion with some extension into the inferior foramen bilaterally.

Intervertebral foramen at the level of l2 spinal canal at level of l 3 subdural space at the level of l4 subarachnoid space at the level of l4; a 60-year-old male presented with a number of unusual signs and symptoms in the facial region. Among others, it was found that the right side of his face was flushed (red).
In the mid and lower cervical regions the roots are under threat from the intervertebral discs, uncovertebral joints and zygapophyseal joints which form the boundaries of the intervertebral foramen. C1 and 2 nerve roots do not run in intervertebral foramina, therefore compression of these nerve roots is not the mechanism for upper cervical pain.

At each segment, spinal nerve roots exit the spine through holes in the back of the vertebrae called foramen.
In the lumbar spine, the transition region between the spinal canal and intervertebral foramen is described as a lateral recess, which is lined with epidural fatty tissue. The spinal canal (or vertebral canal) forms a passage opening for a number of important structures of the human body.
In between c5-c6, the c6 spinal nerve exits the spinal cord through a small bony opening on the left and right sides of the spinal canal called the intervertebral foramen. The c6 dermatome is an area of skin that receives sensations through the c6 nerve.
The intervertebral foramen is formed by the superior and inferior vertebral notches of each adjacent vertebral segment and serves as a passage opening for the spinal nerve, meningeal branch, spinal artery, and intervertebral vein.
The osseous boundaries of the intervertebral compartment are described. Measurements of the pedicles demonstrate that their configuration determines the shape of the intervertebral compartment. The pedicles originate in the upper lumbar spine (l 1 and l 2) in a vertical direction from the posterior aspects of the vertebral bodies.

There are other openings on the stacked vertebrae called the foramina (singular foramen), where the nerve roots branch out of the spinal cord. At every level of the spine, a pair of spinal nerves exits the spinal column through the foramina.
Spinal stenosis occurs when one or more bony openings (foramina) within the spine begin to narrow and reduce space for the nerves. This process can occur within the spinal canal (where the spinal cord runs down the center) and/or in the intervertebral foramina where spinal nerves exit the spinal canal.
