Anatomy and development of the fontanelle.

چکیده
Anterior fontanelles from 19 fetuses over a range of gestational ages (from 8 weeks to full term) were obtained to study the anatomy and development in relation to the application of the principles of fontanometry. The most important feature was the development of an elastic membrane by 23 weeks' gestation; a subcutaneous layer of fat had appeared by 28 weeks' gestation.

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...

Objective(s): This study investigated the possible effects of low (3 mg/kg) and high (6 mg/kg) doses of nicotine on the skeletal development of rat fetuses by the double staining method and the protective role of melatonin (10 mg/kg) against these effects.Materials and Methods: Eighteen adult female Wistar-Albino rats were divided into six groups (n=3, each) as control, low-dose nicotine, high-...
متن کاملReal-time sonographic sector scanning of the neonatal cranium: technique and normal anatomy.
A commercially available wide field of view real-time mechanical sector scanner can be used to image the neonatal cranium. Because of the small transducer head size, the open anterior fontanelle can function as an acoustic window. By thus avoiding bone, higher frequency transducers may be used to improve image resolution. Infants may be scanned quickly without sedation in their isolettes in the...
