A boy has 206 bones, the same number as an adult woman. While the skeletons of men and women have some minor variations, the total number of bones remains the same.
Babies are born with more bones than adults (around 275-300) because many of their bones will fuse together as they grow. This fusion process helps them develop into the 206 bones found in the adult skeleton.
Although boys and girls have the same number of bones, they can have different bone mass, density, structure, and length due to hormonal differences and other factors.
