Definition/Description. Trapezius Myalgia is chronic pain of the upper trapezius muscle, most frequent is neck pain. It is a complex and multifactorial condition. Musculoskeletal pain is often intensifying by mental and social stress at home or work.
A hadron, in particle physics, is any subatomic (smaller than the atom) particle or antiparticle which is made of quarks. Quarks are fundamental particles which among other properties have an electrical charge and a name (e.g. 'up', 'down', 'strange'). The electrical charge of a single quark is always a fraction (e.g. 2/3).
quarks are building blocks for subatomic particles they are considered to be fundamental particles and are thus not made up of other particles quarks bind together with gluons to make composite particles called hadronsthe most common examples of a hadron are neutrons and protonsquarks are assigned names called flavors up down strange charm top and bottomuarks are building blocks for subatomic particles they are considered to be fundamental particles and are thus not made up of other particles quarks bind together with gluons to make composite particles called hadrons
