The document discusses the major muscle groups of the human body. It identifies the localization, origin, insertion, and action of muscles in the front and back of the trunk, arms, and legs. The muscles of the front trunk include the pectorals, abdominals, and obliques. Key back muscles are the trapezius, dorsals, and lumbars. Arm muscles covered are the deltoid, biceps, and triceps.
