Human musculoskeletal system
Human musculoskeletal system
The Human musculoskeletal system (pronunciation: /ˌmjuːskəˈskɛlɪtəl/ system) is an organ system that gives humans the ability to move using their muscular system and skeletal system. The etymology of the term derives from the Greek words muscle (mus) and skeleton (skeletos).
Structure
The human musculoskeletal system consists of the human skeleton, muscles, tendons, ligaments, and joints. These components work together to provide the body with support, stability, and movement.
Human skeleton
The human skeleton is the body part that forms the supporting structure of an organism. It consists of both bones and cartilages.
Muscles
Muscles are soft tissues that produce force and motion. They are primarily responsible for maintaining and changing posture, locomotion, as well as movement of internal organs.
Tendons
Tendons are flexible but inelastic cords of strong fibrous collagen tissue attaching a muscle to a bone.
Ligaments
Ligaments are the fibrous connective tissue that connects bones to other bones.
Joints
Joints are the location at which bones connect. They provide the means for movement.
Function
The human 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 system for calcium and phosphorus.
