The lines that run North-South on the earth and end at the two poles are called the meridians of constant Longitude.
Lines of Longitude
longitudinal lines run north/south; Latitudinal lines run east/west
Longitude lines run from pole to pole.

The lines on a global grid that run from pole to pole are called meridians of longitude. The prime meridian, which passes through Greenwich, London, is the most well-known and has a longitude of 0 degrees. The meridian at 180 degrees, opposite the prime meridian, is called the International Date Line.
Lines of latitude run round the earth parallel to the Equator. Lines of longitude run from pole to pole, crossing the Equator at 90 degrees.
The lines that run from pole to pole are lines of longitude. The Prime Meridian (zero) runs through the Greenwich Observatory, London.
