Myology is the name given to the study of muscles. Muscles are considered to be the meat and flesh of the body, and it is mainly the muscles of the body which are manipulated in massage. Not only is it important for the beauty therapist to know how the muscles lie in the body so that individual muscle or muscle groups can be treated and massaged correctly, but it is essential to know the name, origin, insertion, and action of the muscles if corrective and helpful schemes of exercises are to be planned, in conjunction with massage and a good diet. Every muscle in the body serves a purpose and has a function, but only the superficial individual muscles and muscle groups will be described. These can easily be identified on the living body.
