The interspinal ligaments (interspinous ligaments), thin and membranous, connect adjoining spinous processes and extend from the root to the apex of each process.

They meet the ligamenta flava in front and the supraspinal ligament behind.

They 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.
