Cranial sutures work collectively to distribute strain throughout the reptile skull
The skull is composed of many bones that come together at sutures. These sutures are important sites of growth, and as growth ceases some become fused while others remain patent. Their mechanical behaviour and how they interact with changing form and loadings to ensure balanced craniofacial development is still poorly understood. Early suture fusion often leads to disfiguring syndromes, thus is...
متن کاملFlexure of cranial sutures.
Beam samples containing cranial sutures were prepared from embalmed and unembalmed cranial bone and were tested to determine their flexural stiffness and strength. With the aid of layered beam theory, the flexural stiffnesses of beams containing cranial sutures were compared to hypothetical layered cranial bone beams which did not contain sutures. The bending stiffnesses and strengths of crania...
متن کاملPremature Fusion of Skull Sutures
Graves's disease is uncommon in childhood, only 5% of the total cases falling within the agegroup 0-15 years (Saxena, Crawford, and Talbot, 1964). Excluding the transient neonatal form of thyrotoxicosis, we have been able to trace only 4 cases of hyperthyroidism beginning before 2 years. The purpose of this paper is to describe a boy with Graves's disease who presented in the second year of lif...
متن کاملCranial sutures and diploae morphology.
The aim of the study was to assess the normal cranial suture and bone diploae ultrastructural morphology. Two types of sutures from different specimens were collected. The micro-CT scanning provided a three-dimensional view of the sutures at a microscopic level thus allowing the evaluation of the development stage and a rapid analysis evaluation of bone and diploae morphology. In the meantime, ...
متن کاملThe Morphogenesis of Cranial Sutures in Zebrafish
Using morphological, histological, and TEM analyses of the cranium, we provide a detailed description of bone and suture growth in zebrafish. Based on expression patterns and localization, we identified osteoblasts at different degrees of maturation. Our data confirm that, unlike in humans, zebrafish cranial sutures maintain lifelong patency to sustain skull growth. The cranial vault develops i...
