Musculoskeletal system

Main function The main function of the musculoskeletal system is to provide movement and support for the body, to protect internal organs, and to provide attachment sites for the muscles.

Main organs Muscles Bones Joints Ligaments Tendons Cartilage

muscles Soft tissue that has the ability to relax and contract in order to initiate movement within the body. There are three types of muscle: Cardiac muscles - Involuntary muscle that forms the heart Smooth muscles - Involuntary muscles that control many types of movement within the body (such as digestion). Skeletal muscles - Voluntary muscles attached to bones and provide the force needed to move the bones; tendons connect the skeletal muscles to bones

Bones Provide shape and support for the body, protection for many organs and structures, and attachment sites for muscles; some bones produce blood cells; some store minerals

Joints A place in the skeleton where two or more bones meet. There are many types of joints found in the body.

Ligaments Soft connective tissue that attach bones at the joints.

Tendons Tendons - soft connective tissue that attaches muscles to bones.
