Study Notes
- The skeleton serves as a supporting framework for the body, determining genetic body shape and supporting soft tissues.
- One of the functions of the skeleton is protection, with certain parts like the cranium protecting vital organs such as the brain.
- Muscles attach to the skeleton, allowing movement through origins and insertions on bones, with tendons connecting muscles to bones.
- The skeletal system is responsible for blood cell production, particularly in long bones where bone marrow produces red and white blood cells.
- The skeleton stores minerals like calcium and phosphorus, crucial for bone density, bone growth, and muscular contraction.
- Leverage refers to the ability of the skeleton to move weight and the body, primarily involving the appendicular skeleton and muscles pulling on tendons.
- Weight-bearing is a key function of the skeleton, with bones designed to bear and distribute weight, especially in weight-bearing exercises that increase bone density.
- The skeletal system helps reduce friction across joints through mechanisms like cartilage, synovial fluid, and sesamoid bones like the patella lifting tendons away from the joint.
