You're thinking of the Prime Meridian -- 0 degrees, and the International Date Line -- 180 degrees. Both are lines of longitude.
A line running north and south/ up and down is called a vertical line.
A geodesic line connecting the north and south poles.
The imaginary line that runs through Earth's North and South poles is called the axis or polar axis.
Yes, every line of longitude runs from the North Pole to the South Pole.
A meridian is an imaginary line that runs from the North Pole to the South Pole on Earth. It is used in navigation and mapping to determine longitude. On a map or globe, a meridian appears as a line that connects the geographic poles.
The virtual line that connects the south and north poles and divides the western and eastern hemisphere is called the Prime Meridian. It is located at 0 degrees longitude and passes through Greenwich, England.
Your thinking of the Prime Meridian, which terminates at the poles, and which connects to the International Date Line -- a non-straight line for political reasons, that essentially mirrors the PM, pole to pole.

I thought they were.
No. It has two ends, at the north and south poles.
Those are "meridians of longitude".
