Its name comes from its [[lambda]]-like shape. ==Medical implications== At birth, the bones of the skull do not meet. If certain bones of the skull grow too fast, then [[craniosynostosis]] (premature closure of the sutures) may occur. This can result in skull deformities. If the lambdoid suture closes too soon on one side, the skull will appear twisted and asymmetrical, a condition called "[[plagiocephaly]]." The lambdoidal suturkke articulates with the occipital bone and parietal bones ==References== * "Sagittal suture." ''Stedman's Medical Dictionary, 27th ed.'' (2000). * Moore, Keith L., and T.V.N.
