"In particle physics, the quark is one of the two basic constituents of matter (the other is the lepton). It is quarks that make up protons and neutrons, with there being exactly three quarks within each kind of particle.
There are six different types of quark, usually known as flavors: up, down, charm, strange, top, and bottom. (Their names were chosen arbitrarily based on the need to name something that could be easily remembered and used.)" Wikipedia
