Lamdoidal, also spelled as lambdoidal, is an adjective that relates to or describes the posterior portion of the human skull. The term "lamdoidal" is derived from the lambda-shaped suture found on the back of the skull, which connects the parietal bones with the occipital bone. This suture is named after the Greek letter "lambda" (Λ) due to its resemblance to the uppercase form of the letter.
In anatomical terms, the lamdoidal region refers to the area surrounding the lambdoidal suture. It encompasses the lower part of the occipital bone, forming the base of the skull, and the posterior portion of the parietal bones. This area plays a significant role in protecting the back of the brain and is involved in maintaining the overall structure and stability of the skull.
The lamdoidal suture, along with other sutures of the skull, helps in the process of skull growth and development. During infancy and childhood, the sutures permit the expansion of the skull to accommodate the growing brain. In adulthood, the sutures become more rigid and fuse, contributing to the overall strength and stability of the skull.
Various medical professionals, such as anatomists, neurologists, and surgeons, utilize the term "lamdoidal" when referring to the specific anatomical features, characteristics, and structures associated with the posterior aspect of the skull, including the lambdoidal suture.
