I have tagged the claim "The lower curvature of the arch has a lower pressure than the upper curvature. This is where the ductus arteriosus is connected during the fetal stage" as dubious; per , ductus arteriosus connects to the descending aorta, not the arch. --Eleassarmy talk 05:40, 9 July 2015 (UTC)
@Eleassar I am unsure about what we should write here. From my understanding the remnant of the duct the ligamentum arteriosum connects to the arch of aorta. In addition my Gray's Anatomy 40th edition states that the ductus arteriosus connects to the arch of aorta. On the other hand you have a source which states otherwise. I will as at the talk page of WikiProject Anatomy. Depending on the answer, or by providing a cleverly-phrased middle ground, we will change a few articles. --Tom (LT) (talk) 10:14, 10 July 2015 (UTC)
During the course of dissecting a rat, we would like to include a section that compares the anatomical similarities and differences between the aortic arch of humans compared to rodents (specifically the rat). Here is a possible source that we would use to derive such information from, or follow as an example from our own dissection of the rat: Ciszek, B., Skubiszewska, D., and Ratajska, A. 2007.
