Becker's muscular dystrophy in the arms, neck, and other areas, but not as noticeably severe as in the lower half of the body. Calf muscles initially enlarge during the ages of 5-15 (an attempt by the body to compensate for loss of muscle strength), but the enlarged muscle tissue is eventually replaced by fat and connective tissue (pseudohypertrophy) as the legs become less used (with use of wheelchair). Possible complications associated with muscular dystrophies (MD) are cardiac arrhythmias. Becker muscular dystrophy (BMD) also demonstrates the following: The disorder is inherited with an X-linked recessive inheritance pattern. The gene is located on the X
Human musculoskeletal system Human musculoskeletal system The human musculoskeletal system (also known as the locomotor system, and previously the activity system) is an organ system that gives humans the ability to move using their muscular and skeletal systems. The musculoskeletal system provides form, support, stability, and movement to the body. It is made up of the bones of the skeleton, muscles, cartilage, tendons, ligaments, joints, and other connective tissue that supports and binds tissues and organs together. The musculoskeletal system's primary functions include supporting the body, allowing motion, and protecting vital organs. The skeletal portion of the system serves as the main storage
