Meaning of Isthmus
What is Isthmus:
As isthmus it is called, in Geography, the strip of land that joins two continents, or a peninsula with a continent. Also, in Anatomy, the isthmus is called the narrowest part of an organ that communicates two cavities.
The word, as such, comes from Latin isthmus, and this, in turn, from the Greek, ἰσθμός (isthmos), which means ‘narrow passage’.
The best known isthmus are the Isthmus of Panama and the Isthmus of Suez due to the construction of artificial sea lanes that join two points separated by the isthmus such as the Panama Canal and the Suez Canal.
