The medical term that means inflammation of the root of a spinal nerve is radiculitis.
Explanation
- "Radiculitis" breaks down into "radic-" meaning root (referring to the nerve root) and "-itis" meaning inflammation.
- Radiculitis causes inflammation and pain in the spinal nerve root, often resulting from conditions such as a herniated disc or other factors irritating or compressing the nerve root.
- It is closely related to radicular pain and radiculopathy, which involve nerve root irritation or disease, but the specific term for inflammation is radiculitis.
Thus, radiculitis is the correct medical term for inflammation of the root of a spinal nerve.
