The muscular system is an essential part of the body that comprises over 650 muscles. These muscles play various roles in the body such as providing strength, balance, posture, movement, joint stability, and muscle metabolism. Muscles make up around 40% of the body’s weight and can be broadly categorized into three types: skeletal, cardiac, and smooth. Cardiac and smooth muscles are involuntary and controlled by the autonomic nervous system, while skeletal muscles are voluntary and controlled by the central nervous system. Each muscle in the body has skeletal muscle, nerve, vascular, and connective tissues. These muscles usually work in pairs, with one muscle responsible for extending while the other is responsible for bending. The skeletal muscles work with joints and bones to produce different body movements such as walking, running, breathing, and facial expressions. They also provide joint stability, posture, and heat production. Skeletal muscles are categorized by body group, such as head and neck muscles, trunk muscles, and arm/leg muscles. Massage therapy can provide numerous benefits for the muscular system, including stimulating the circulatory and nervous system, enhancing cell activity, and waste removal in the lymph system. It can also help to improve flexibility, increase range of motion, enhance muscle tone, assist in post-operative rehabilitation, and manage pain. Additionally, massage therapy can help to release facial constrictions and decrease fibrous adhesions from muscle tissue injuries or immobilization. It can also assist in warming up or warming down before or after muscle exercise, improving posture, balance, and movement
