When describing a freely movable joint, which term should be used?

The musculoskeletal system is made up of bones, muscles, joints, cartilage, ligaments, and tendons. The main functions of the system are to provide support and flexibility, protect vital organs, and facilitate movement.  Here's some information about the structure and function of each component of the musculoskeletal system: Bones: Provide structure and support the body, protect vital organs, and store nutrients and minerals. Bones also help produce blood cells. Joints: Allow for motion and movement, and provide stability. Bones form joints, which act as levers that muscles pull on to... Show more

The musculoskeletal system is made up of bones, muscles, joints, cartilage, ligaments, and tendons. The main functions of the system are to provide support and flexibility, protect vital organs, and facilitate movement. 

Here's some information about the structure and function of each component of the musculoskeletal system:
Bones: Provide structure and support the body, protect vital organs, and store nutrients and minerals. Bones also help produce blood cells.
Joints: Allow for motion and movement, and provide stability. Bones form joints, which act as levers that muscles pull on to produce movement.
Muscles: The driving force behind the musculoskeletal system, enabling movement such as sitting, standing, walking, and talking. Muscles also keep the heart beating and help with breathing. Muscles must be able to react to stimuli, contract, extend, and return to their normal shape.
Tendons: Anchor muscles to bones, allowing muscle contractions to move the bones of the skeleton.
Ligaments: Connect neighboring bones to keep the skeleton intact, and provide support to joints. Ligaments are found around the knees, ankles, elbows, shoulders, and other joints.
