The primary component of the human skeleton is bone, which provides structure, protection, and support for the body. The human skeleton consists of approximately 206 bones in adulthood, which are interconnected by joints and ligaments. Bones also serve essential functions beyond mere support; they store minerals such as calcium and phosphorous, play a role in blood cell formation through bone marrow, and act as levers for muscles to facilitate movement. The skeleton undergoes constant remodeling throughout life, adapting to stress and changes in physical activity. Its complex design is crucial for maintaining overall health and mobility.
