Any line that joins the north and south poles has the same longitude
at every point on it. It's called the 'meridian' of that longitude.
the prime meridian
Lines of longitude.
meridians
longitude
The lines that run north and south are called meridians of longitude. (The north and south poles are the ends of every meridian, so each one only goes half-way around the globe.)
Every meridian is an imaginary semi-circle between the north and south poles. There are an infinite number of them, each one is more than 12,000 miles long, and every point on the same meridian has the same longitude.
Earth's Axis
line of longitude. Or a longitudinal line.
The imaginary lines that run from north to south are called lines of longitude. The most significant one is the international date line, which divides the extreme east from the extreme west.

An imaginary line which runs round the globe, called the "equator".
Assuming the question is about the prime meridian, it is the imaginary line joining the North and South poles which passes through a specific point in the Greenwich observatory in London.

longitudinal lines run north/south; Latitudinal lines run east/west
Earth spins around its axis(or imaginary line from the north pole to the south pole) by gravity from earth itself and the surrounding planets.
