Concepts Used:
The Musculoskeletal System
The musculoskeletal system comprises bones, cartilage, ligaments, tendons, and connective tissues. The skeleton contributes a framework for the muscles and other soft tissues. Together, they hold up our body’s weight, maintain our posture and help us move.
The parts of the musculoskeletal system are:
- Bones: Bones of all shapes and sizes support our body, protect organs and tissues, store calcium and fat, and make blood cells. A bone’s hard outside shell encircling a spongy center. Bones provide structure and form for our bodies. They work with muscles, ligaments, tendons, and other connective tissues to help you move.
- Cartilage: Cartilage cushions bones inside our joints, along our spine, and in our ribcage. Firm, rubbery cartilage secures bones from rubbing against each other. We also have cartilage in our nose, ears, pelvis, and lungs.
- Joints: Bones come together to build joints. Some of the joints have a large range of motion like the ball-and-socket shoulder joint. Other joints such as the knee allow bones to move back and forth but not rotate.
- Muscles: Each muscle is made of thousands of extending fibers. our muscles allow us to move, sit upright and stay still. Some muscles help us to run, dance and lift. We use others to write our name, fasten a button, talk and swallow.
- Ligaments: Made of tough collagen fibers, ligaments attach bones and help stabilize joints.
- Tendons: Tendons associate muscles with bones. Made of fibrous tissue and collagen, tendons are resilient but not very stretchy.
