1-1. THE MUSCULOSKELETAL SYSTEM
a. The musculoskeletal system is composed of bones, joints, muscles, cartilage, ligaments, and tendons. The skeleton provides a structural framework for the body and, because bones are rigid, provides support and protection for vital organs and softer tissues. Skeletal muscles and bones work together to make body movement possible. Blood cell formation (called hematopoiesis) occurs in bone marrow, and bones store minerals such as calcium and phosphorus.
b. Orthopedics is the branch of medicine and surgery that is concerned with the preservation and restoration of the function of the skeletal system, its articulations (joints), and its associated structures by medical, surgical, and physical means.
c. Refer to figure 1-1 to refresh your knowledge of the names and locations of the major muscles and bones.
