Multiple Wormian bones at the lambdoid suture in an Indian skull
نویسنده
چکیده
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 lambdoid suture.

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...

Introduction Frontal bone is one of the unpaired bones of the skull. The bone develops in two halves and presents a metopic suture between the two in the fetal life; however, the suture disappears completely before or shortly after birth. Bregma is the meeting point of the sagittal and coronal sutures. It is represented by the anterior median fontanelle in the fetal life. The fontanelle obliter...
