The term isthmus that we are now dealing with, we can establish that it has its etymological origin in Latin, specifically in the word “isthmus”. A word this that, in turn, comes from the Greek “isthmos”, which can be translated as “narrow passage”.
A isthmus is a portion of Earth which enables join a peninsula with a continent or link two continents.
The isthmus are strips of land that link two larger sectors of land through the sea. In this way, they become the only way to unite the two regions by land.
It is usual that, by action of the human being, the isthmus is crossed by a channel. These engineering jobs are carried out to facilitate maritime transport: by having the possibility of crossing the isthmus by boat, the route is shortened, since it is not necessary to skirt the continent or the peninsula. The channels, in this framework, create a direct passage between those seas that the isthmus is responsible for separating.
The isthmus of Panama, for example, separates the Atlantic Ocean of the Pacific Ocean. It extends for about 700 kilometers, with a width that ranges from 50 to 200 kilometres.
At isthmus of Panama the Panama Canal, a waterway inaugurated in 1914 that allows you to go from Caribbean Sea (Atlantic Ocean) to the Pacific Ocean and vice versa. This construction site, developed from a system of locks, revolutionized international trade by facilitating exchanges.
In the same way, we cannot ignore that another of the most important isthmus is Corinth, which is the strip of land that joins what is the area of mainland Greece, which responds to the name of Hellas. , with the Peloponnese peninsula. It is bathed by the Aegean Sea and the Ionian Sea and, in addition, it should be noted that it was important in Greek mythology. Specifically, it is considered to have been the subject of a dispute between Poseidon and Helios.
Since the 19th century this isthmus has been crossed by the Corinth Canal, of which we can also point out that it has a width that ranges from 16 kilometers in its widest area to 6 kilometers in its narrowest part.
Likewise, we cannot forget the existence of the Isthmus of Tehuantepec, which is located in Mexico, specifically between the states of Oaxaca and Veracruz, and which is the narrowest area that exists between the Atlantic Ocean and the Pacific Ocean. Specifically, it is approximately 200 kilometers wide and stands out, among other things, because it is a very rich area in terms of resources, with oil taking special relevance.
It should be noted that the idea of isthmus also appears in the anatomy. The brain isthmusIn this framework, it is the part of said set of organs where the cerebellum and the brain join. The isthmus of jawsmeanwhile, it is the opening between the pharynx and the mouth.
