As the spinal disc becomes less elastic, it can rupture. When the disc ruptures, a portion of the spinal disc pushes outside its normal boundary--this is called a herniated disc. When a herniated disc bulges out from between the vertebrae, the spinal nerves and spinal cord can become pinched. There is normally a little extra space around the spinal cord and spinal nerves, but if enough of the herniated disc is pushed out of place, then these structures may be compressed.
Herniated Nucleus Pulposus (HNP) - medical terminology for the following: Lumbar radiculopathy; Cervical radiculopathy; Herniated intervertebral disk; Prolapsed intervertebral disk; Slipped disk; Ruptured disk A herniated nucleus pulposus is a slipped disk along the spinal cord. The condition occurs when all or part of the soft center of a spinal disk is forced through a weakened part of the disk. definition comes from the Univ. of Maryland Medical Center web site.
Vertebral foramen are the spaces between adjacent vertebrae where the spinal nerves exit the spinal canal.

Intervertebral Foramina
The main difference between the vertebral foramen and the intervertebral foramen in the spinal column is that the vertebral foramen is a single opening within each vertebra that allows the spinal cord to pass through, while the intervertebral foramen are openings located between adjacent vertebrae that allow spinal nerves to exit the spinal cord and travel to the rest of the body.
That is called a herniated disc, also known as a slipped disc or ruptured disc. It can cause pain, weakness, or numbness in the back or legs due to pressure on the spinal nerves. Treatment may involve rest, physical therapy, medications, or in severe cases, surgery.
The spinal nerves exit from the vertebral column through openings between adjacent vertebrae. These openings, called intervertebral foramina, are located just in front of the facet joints. They exit from what are called intervertebral foramina (foramen means opening).
You can get herniated discs.
There is narrowing of the spinal canal in spinal stenosis. This happens due to swollen ligamentum flavum or due to protrusion of the intervertebral disc or some other reason.
A herniated disc is an injury that can occur to your spinal cord and/or the roots of your nerves. It can be extremely painful for one to experience.
