neural foramina
Pronunciation: NOOR-al for-AH-min-ah
Openings between adjacent vertebrae through which nerve roots exit the spinal canal.
Full Definition
The neural foramina (singular: foramen) are bilateral openings formed between adjacent vertebrae that allow spinal nerve roots to exit the central spinal canal and travel to the periphery. Each foramen is bounded by the pedicles above and below, the facet joints posteriorly, and the intervertebral disc anteriorly. Narrowing of these openings (foraminal stenosis) can compress nerve roots and cause radiculopathy.
Usage
Usage note: Plural form; singular is 'neural foramen'. Critical anatomical landmark in spine surgery.
