"Lines" of constant longitude are "meridians".
Lines of longitude, or meridians.
"Lines of longitude" are conceptual, not physical; there can be as many as we want. For example, there are 3600 "seconds of longitude" between each degree of longitude. That's 60 minutes of arc per degree, and 60 seconds of arc per minute.
