Interactive map of the countries in Central America and the Caribbean. Central America is the southernmost part of North America on the Isthmus of Panama, that links the continent to South America and consists of the countries south of Mexico: Belize, Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica, and Panama.

Explanation:

Central America, southernmost region of North America, lying between Mexico and South America and comprising Panama, Costa Rica, Nicaragua, Honduras, El Salvador, Guatemala, and Belize.

The Isthmus of Panama (Spanish: Istmo de Panamá), also historically known as the Isthmus of Darien (Istmo de Darién), is the narrow strip of land that lies between the Caribbean Sea and the Pacific Ocean, linking North and South America. It contains the country of Panama and the Panama Canal.

Geography. Central America is a connecting isthmus. This isthmus arguably starts with the isthmus of Tehuantepec in Mexico (line 3 in the image below), which would mean that a small portion of Mexico is in Central America. Since that is only a tiny part of Mexico, the country is not part of Central America.
