study, the types of craniosynostosis that generate a more elongated shape of the skull (dolichocephaly) and the types that generate a rounder shape (brachycephaly) have been considered, and it has been analyzed how this condition affects the anatomy of the blood vessels of the cranial cavity. “In particular, we have studied the morphology of the middle meningeal artery, the venous sinuses, and the emissary veins, through the traces that these vessels leave in the bone”, explains Emiliano Bruner. Brain pressure In the most extreme cases of craniosynostosis (very elongated skulls), the development of the meningeal artery changes its course to passively follow the spatial variations of the endocranial cavity. But the most interesting result concerns

the vessels responsible for regulating the flow of blood, which India WhatsApp Number List present many differences in people with craniosynostosis. In these individuals, a posterior drainage system, the occipito-marginal system, is frequently detected, which is rare in normal skulls. In addition, they have larger and more frequent emissary veins, which is suspected to be related to the brain pressure problems suffered by individuals with these abnormalities. “The use of cranial traces allows us to investigate these vascular features in very large samples, such as museum collections, in populations from the past, and in fossil species. Therefore, investigating these types of traits is of interest in anthropology, bioarcheology, and medicine, ”says Bruner. This study was carried out by
