There are typically 206 bones in an adult human body. These bones form the human skeleton, providing structure, protecting vital organs, and enabling movement. The number of bones can vary slightly among individuals due to some bones being fused together. For example, the bones in the spine can vary in number due to individual differences. Infants are born with around 270 bones, but many of these fuse together during growth and development, leading to the standard number observed in adults.
