What is the main function of bones in the musculoskeletal system?

The primary function of bones in the musculoskeletal system is to support and protect the body. Bones form the structural framework that gives the body its shape and strength. They provide support for muscles, organs, and other tissues, enabling the body to maintain its posture and withstand various forces. Additionally, bones protect vital organs; for example, the rib cage safeguards the heart and lungs, while the skull encases the brain.

While bones play roles in other functions, such as facilitating movement through joints and serving as sites for muscle attachment, their critical roles in supporting the body's structure and protecting internal organs cannot be understated. Functions like hormone regulation and bile storage are associated with other systems within the body, such as the endocrine and digestive systems, respectively. Understanding these foundational roles of bones helps clarify their importance in overall health and movement.
