The Ural Mountains that run north-to-south in Russia, are the primary landform that divides Europe from Asia.
Farther south, the Caucasus Mountains run west-to-east between the Black Sea and the Caspian Sea. Although Georgia and Armenia (south of these mountains) are often considered part of Eastern Europe, Anatolia in Turkey is considered western Asia.
The Cell Membrane forms the outside boundary that separates the cell from its environment.
In cells without a cell wall, the outside boundary that separates the cell from its environment is formed by the cell membrane or plasma membrane. This phospholipid bilayer regulates the passage of molecules in and out of the cell, allowing for selective permeability.

The relative superior endpoint of the nasopharynx is the skull base, which separates it from the base of the skull. The relative inferior endpoint is the upper surface of the soft palate, which forms the boundary between the nasopharynx and the oropharynx.

Spain is in Europe, so there is no mountain range that divides Spain from Europe. What you are referring to is the Pyrenees Mountains, which forms much of Spain's border with France. As Spain is in the southeast of Europe, it could be looked upon as a boundary between Spain and most of the rest of Europe.

The continent of Europe forms a peninsula, largely surrounded by water on three sides: the Atlantic Ocean to the west, the Mediterranean Sea to the south, and the Arctic Ocean to the north.
The Ural Mountains form the eastern boundary of Europe. These mountains separate Europe from Asia and stretch approximately 1,550 miles from north to south.
