herniated disk
Inter-vertebral disc
Each spinal disc is made of two parts:Nuclues pulposusAnnulus fibrosusThe nucleus pulposus is the central or inner part of the disc structure that is located between each of the spinal vertebrae. It is a soft and spongy gel-like material that is about 75% water.The annulus fibrosis is outer part of the disc structure. It is made of layers of tough collagen tissue surrounds the nucleus pulposus to protect it and keep it in place.
The part between the vertebrae is called the intervertebral disk. In the center of the disk is a the spngey part called the nucleus pulposus.
the joint formed by the bodies of two adjacent vertebrae separated by an intervertebral disc is a symphysis joint. Each intervertebral disc is composed of a band of fibrocartilage (annulus fibrosus) that surrounds a gelatinous core (nucleus pulposus). the disc absorbs shocks and helps equalize pressure between the vertebrae when the body movies. Each disc is slightly flexible, so the combined movement of many of the joints in the vertebral column allows the back to bend forward or the the side or to twist. they are amphiarthrotic joints because these joints allow slight movement.
myelography
722.2 is the code for HNP when the site is unspecified. This is what's called a "herniated disk" in lay terms.
herniated disk
HNP is an acronym for herniated nucleus pulposus.
also commonly called a herniated nucleus pulposus, prolapsed disk, ruptured disk, or
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.
You have posterior longitudinal ligament on the back side of the body of the vertebrae and discs. So there is herniation of the nucleus pulposus, coming out of the tear in the annulus fibrosus.
There is no plural form of pulposus. Nucleus pulposus refers to the jelly-like substance in the middle a the spinal disc.
No desiccation indicates some kind kind of break down in the disk itself. Herniating a disc is to have it moved out of position (pinched or something like that) which can in some cases be fixed.
An intervertebral disk in which the nucleus pulposus has protruded through surrounding fibrocartilage. This occurs most frequently in the lower lumbar region.

Inter-vertebral disc
The two parts of the intervertebral disc are the nucleus pulposus and the annulus fibrosis. The nucleus pulposus is considered the central portion while the annulus fibrosis is the anterior area of the disc.
