The more we discover about our Universe, the more we realize just how strange and wonderful it is. When Pluto was discovered 80 years ago, we never could have expected the variety of objects in the Solar System. Categorizing Pluto as a dwarf planet helps us better describe our celestial home.
A more detailed neurosonographic evaluation is done in additional coronal and sagittal planes, visualised ideally with transvaginal ultrasound through the anterior fontanelle. Place the vacuum cup on the occiput of the fetal cranium toward the anterior fontanelle. 1] The anterior fontanelle is the unossified area of the skull situated at the junction of the frontal, coronal, and sagittal sutures.
This fontanelle usually closes during the first several months of an infant's life. There is also a much larger, diamond-shaped anterior fontanelle where the two frontal and two parietal bones abut. This fontanelle remains open until the child is about two years of age. In cleidocranial dysostosis it is often late in closing or never closes. The anterior fontanelle is useful clinically.
