Anatomical terminology

The interspinal ligaments (interspinous ligaments) are thin and membranous ligaments, that connect adjoining spinous processes of the vertebra in the spine.[1][2][3] They extend from the root to the apex of each spinous process. They meet the ligamenta flava in front and blend with the supraspinal ligament behind.[2]

The ligaments are narrow and elongated in the thoracic region, broader, thicker, and quadrilateral in form in the lumbar region, and only slightly developed in the neck.[1] In the neck they are often considered part of the nuchal ligament.[2]

The function of the interspinal ligaments is to limit flexion of the spine.[2]
