The
lambdoid suture (or
lambdoidal suture) is a dense, fibrous
connective tissue joint on the posterior aspect of the
skull that connects the
parietal and
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 suture articulates with the occipital bone and parietal bones
