The correct term for the Turkey comment is (no lie) Eurasia - WARNING HISTORICAL AND GEOGRAPHICAL CONTENT FOLLOWS!! During the early period of Western civilization, the areas were defines by their association with various water bodies, not land bodies - ie the Aegian, the Mediterranian, the Black, Red and Dead seas, etc. During the late eras of the BC (or BCE for modernists) regions began affixing themselves to land titles. Mostly thanks to the Alexander the Great, but also thanks to the Persian and Egyptians before him and the Romans thereafter (that is a loose generalization bacause I don't want to write a book - please bear with me)
The area that was west of Europe was known as Asia by the 1st century AD (or CE for modernists). The lands that we think of as culturally Asian, were undiscovered until Marco Polo, by which time, the "continent" train of thought was already in vogue (even though it was many years before it was fully realized). So the Rus, the Ottomans, the Goths, the Slavs and the Huns were all Eurasian, while the oriental societies became Asian. Later the term Middle-eastern came into practice, but the "damage" per se was already done.
Please not that this is a quick and dirty history/geography lessons and MANY MANY MANY things have been editied, left out and abridged for space sake. Please no trolls, if you want more information, take a history course.
Oh and BTW, Panama is on the North American continent in the Central American landmass.
