The '''lambdoid [[suture (anatomical)|suture]]''' (or '''lambdoidal suture''') is a dense, fibrous [[connective tissue]] [[joint]] on the posterior aspect of the [[skull]] that connects the [[parietal bone|parietal]] and [[temporal bone|temporal]] bones with the [[occipital bone]].
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
