There are five musculoskeletal system functions: structure and support, movement, protection of vital organs, storage and supply of calcium and phosphate, and hematopoiesis The structure and function of the musculoskeletal system has been a focus of this section.

Bones, muscles, tendons, ligaments, collagen, and other connective tissue are the major structures of this body system. Under normal circumstances and with normal abilities, the musculoskeletal system is a fine-tuned machine, delivering on its many functions flawlessly.

musculoskeletal system — composed of bones, muscles, joints, tendons, ligaments, and cartilage that support the body, allow movement, and protect vital organs. skeletal system — the body system composed of bones and cartilage. tendon — band of fibrous collagenous tissue that provides a continuation of the muscle sheath to enable muscle attachment to the periosteum of bones. ligament — band of tissue that connects bones to one another, provides support and stability, and enhances joint movements.
