Isthmus


The word isthmus comes from Latin roots, specifically from the word “isthmus”, which in turn derives from the ancient Greek “ἰσθμός”. Commonly this term is used in geography, where it is understood or called isthmus to the strip, strip or narrow piece of land, which unites two larger extensions of land, which generally said extensions are surrounded by water, except the sector where the isthmus is located, which can unite islands, continents, a peninsula with the mainland, or an island with the mainland.

The best known isthmuses are the Isthmus of Panama that joins the Atlantic Ocean with the Pacific Ocean, and which is the central knot in the geography of the American countries, and has had notable importance in the history of the American continent.
