What does the skeletal system primarily consist of?

The skeletal system is primarily composed of bones and connective tissue. Bones form the rigid structure that supports the body, protects vital organs, and allows for movement by providing leverage for muscles. Connective tissue, such as cartilage and ligaments, plays a crucial role in maintaining the integrity and flexibility of the skeletal system by connecting bones to other bones and cushioning joints, respectively. This composition ensures that the skeletal system fulfills its primary functions, including support, protection, movement, and mineral storage. Understanding this structure is key in fields like biology and medicine, as it forms the foundation for many physiological functions and provides insights into various health conditions related to the bones and joints.
