Legend

The afterward tables of analysis accept seven columns:

• Muscle, artlessly the name of the muscle
• Origin, the anchored adapter point of one end of the beef that does not move during a muscle contraction (usually a bone)
• Insertion, the adverse adapter point, which does move if the beef affairs (usually a bone)
• Artery, the capital barge that feeds claret to the muscle
• Innervation, the capital assumption that food motor ascendancy to the muscle
• Action, the arresting aftereffect of the beef contraction/relaxation (see biomechanics and human kinetics for more)
• Antagonist, a beef with the according but adverse action

Often, a beef is disconnected into added muscles; for example, the quadriceps femoris muscle is added subdivided into the rectus femoris, vastus lateralis, vastus intermedius and vastus medialis. In these cases, the name of the beef accumulation is italicized and the basic analysis are indented. An archetype appears to the right.

For added advice on abounding of the agreement acclimated aural these tables, see anatomical agreement of location, anatomical agreement of motion, medical terminology, list of animal anatomical features and outline of animal anatomy.
