LAMBDOID SUTURE Meaning and
Definition
-
The lambdoid suture is a term used in anatomical and medical contexts to describe a specific type of cranial suture. A suture refers to the fibrous joint that connects two bones, typically found in the skull. The lambdoid suture is specifically located at the posterior (back) region of the skull, and resembles the Greek letter "lambda" (Λ) in shape. It is formed by the articulation between the occipital bone, which is located at the lower rear part of the skull, and the parietal bones, which are situated on the sides and top of the skull.
The lambdoid suture serves a crucial role in skull development during infancy and childhood. It allows for flexibility and growth of the skull, which is particularly important during brain development and as the individual grows. Although it is commonly present in infants and children, the lambdoid suture generally closes and fuses with the surrounding bones by adulthood. The closure of the suture marks the completion of cranial growth and typically occurs between the ages of 20 and 30.
Understanding the anatomy of the lambdoid suture is essential in various medical fields, including neurosurgery, radiology, and anthropology, as it helps in evaluating the development and abnormalities of the skull. Abnormalities, such as a premature fusion or closing of the lambdoid suture, can result in craniosynostosis, a condition characterized by an abnormal head shape and potential complications related to brain growth. Correct anatomical knowledge of the lambdoid suture is fundamental in diagnosing and managing such conditions.

Etymology of LAMBDOID SUTURE
The word "lambdoid suture" is derived from the Greek letter lambda (Λ), which resembles the shape of the suture when viewed from above. In Greek, the word "lambda" denotes the eleventh letter of the alphabet and is pronounced as "lambdά" (lam-tha) in modern Greek. The term "lambdoid" is therefore used to describe the shape of this specific suture, which runs along the back of the skull and separates the parietal bones from the occipital bone.
