The musculoskeletal system (MOS) of the human body consists of:
- skeleton (including ligaments and joints);
- and skeletal muscles.
The skeleton is the passive part of the ODS, and the muscles are the active part.
Together they form a system as muscle contraction sets the bones of the skeleton in motion.
The main functions of the musculoskeletal system are:
The skeleton performs supporting and protective functions, since the bones of the skeleton, connected by ligaments and joints, support other organs and systems, and also protect them from possible external influences.
so, the brain is located in the cranial cavity and is protected by its bones; the lungs and heart are protected by the chest – etc.
Skeletal muscles perform motor functions. The bones attached to the muscles are set in motion like levers.
Muscles also have a protective function.
the abdominal organs are protected from external influences not only by the spine and pelvic bones, but also by the muscles of the back and abdomen.
In addition, ODS participates in the metabolism in the body (mineral, protein) and performs a hematopoietic function (blood cells are formed in the red bone marrow of the spongy bones).
