SUTURAL BONES Meaning and
Definition
-
Sutural bones, also known as wormian bones or intra-sutural bones, are small and irregularly shaped bones found along the sutures or junctions between the cranial bones. These bones are not present in every individual but can occur sporadically, resulting in individual variations among people.
The sutural bones are marked by their unique morphology, which distinguishes them from the main cranial bones. They are typically small, flat, and angular, with a size ranging from just a few millimeters to a centimeter. Furthermore, they possess a smooth surface and are usually located at the intersection of two or more cranial sutures.
The exact formation and function of sutural bones remain somewhat unclear, but several theories have been proposed. One theory suggests that they may develop as a result of excessive ossification or incomplete fusion at the sutural junctions during embryonic development. Another hypothesis suggests that sutural bones could be the outcome of compensatory mechanisms in response to external factors like trauma, hormonal imbalances, or genetic factors.
Although sutural bones are generally considered as normal anatomical variations, they can occasionally be associated with certain medical conditions. For instance, individuals with certain genetic disorders, craniosynostosis (premature fusion of cranial sutures), or osteogenesis imperfecta (brittle bone disease) may exhibit an increased occurrence of sutural bones.
Overall, sutural bones serve as an intriguing element within the study of human anatomy, contributing to the unique characteristics and variations among individuals.

Etymology of SUTURAL BONES
The etymology of the word "sutural bones" can be broken down as follows:
1. "Sutural" is derived from the Latin word "sutura", meaning "a seam or a stitch". In anatomy, a suture refers to the line of junction between two bones, particularly in the skull. It is where the bones are joined tightly together with non-moving fibrous connective tissue.
2. "Bones" is derived from the Old English word "ban", which means "bone" or "osseous tissue". This term refers to the rigid structures that make up the skeleton of vertebrates.
Thus, "sutural bones" refers to the small bones found in the sutures of the skull, where two bones are firmly connected. These bones are commonly referred to as "wormian bones" or "intrasutural bones" as well.
