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.
For the embryological structure, see Aortic arches. The aortic arch, arch of the aorta or the transverse aortic arch (English pronunciation: /eÉªËÉrtÉªk/) is the part of the aorta between the ascending and descending aorta. The arch travels backward, so that it ultimately runs to the left of the trachea.t this point the aortic arch continues as the descending aorta. The aortic arch has three branches. The first, and largest, branch of the arch of the aorta is the brachiocephalic trunk, which is to the right and slightly anterior to the other two branches and originates behind the manubrium of the sternum.
