Human skull with complete metopic suture and multiple sutural bones at lambdoid suture – a case report
Introduction Frontal bone of the skull develops in two halves during the fetal life separated by the metopic suture. The suture normally disappears soon after the birth [1]. The persistent complete metopic suture extending from the nasion to bregma is called metopism [2]. Lambda represent the meeting point of the sagittal and lambdoid suture. It represents the site of posterior median fontanel ...
متن کاملMultiple Wormian bones at the lambdoid suture in an Indian skull
The ‘Wormian bones’ or ‘sutural bones’ are small bones found at the sutures of the skull. They are unnamed bones because they vary from person to person in number and shape. They are commonly found in relation to the frontal and occipital bones. It is important to know about these bones because they can mislead in the diagnosis of fracture of skull bones. We saw a series of sutural bones in the...
متن کاملThree-dimensional sonographic description of the fetal frontal bones and metopic suture.
OBJECTIVE To describe the morphology of the frontal bones and metopic suture at 9-34 weeks of gestation using three-dimensional (3D) ultrasonography. METHODS This was a cross-sectional study of the frontal bones and metopic suture in 16 fetuses at 9-34 weeks of gestation. 3D ultrasonography was used to obtain volumes of the whole fetal skull in the mid-sagittal plane. The volumes were analyze...
متن کاملUnusual presence of Wormian (sutural) bones in human skulls.
Wormian bones are a subset of the small intrasutural bones that lie between the cranial sutures formed by the bones of the skull vault. They are formed due to additional ossification centres in or near sutures. They are usually considered as normal variants and seem to be determined genetically in certain populations. They have been linked with rapid cranial expansion as they appear in great nu...
متن کاملMorphometric Analysis of Accessory Sutural Bones Association With Parietal Emissary Foramina
Background: The sutural bones and fontanelle of the skull display unique morphological characters. Sutural bones are also called supernumerary bones or ossicles or Wormian bones (WB). These are irregular and develop from the independent ossification centers present along the cranial sutures. They appear on periosteal and endosteal surfaces of the skull with variations in size, number, shape, an...
