Example of formatting used in tables to denote muscles and muscle groups.

The following tables of muscles have six columns:

  • Muscle, simply the name of the muscle
  • Origin, the fixed attachment point of one end of the muscle that does not move during a muscle contraction (usually a bone)
  • Insertion, the opposite attachment point, which does move when the muscle contracts (usually a bone)
  • Artery, the main vessel that feeds blood to the muscle
  • Vein, the main vessel into which blood used by the muscle drains
  • Action, the visible result of the muscle contraction/relaxation (see biomechanics and human kinetics for more)
  • Antagonist, a muscle with the equal but opposite action

Often, a muscle is divided into other muscles; for example, the quadriceps femoris muscle is further subdivided into the rectus femoris, vastus lateralis, vastus intermedius and vastus medialis. In these cases, the name of the muscle group is italicized and the component muscles are indented. An example appears to the right.
