The human adult body typically has 206 bones. However, this number can vary slightly from person to person due to the presence of accessory bones or variations in the number of bones in the hands and feet. Babies are born with around 270 bones, but as they grow, some of these bones fuse together. For example, the bones in the skull fuse as a child develops, reducing the number of bones.
The adult human skeleton is divided into two main parts: the axial skeleton, which includes the skull, vertebral column, and ribcage, and the appendicular skeleton, which comprises the bones of the limbs and the girdles that attach the limbs to the axial skeleton. The axial skeleton accounts for about 80 bones, and the appendicular skeleton contributes the remaining 126 bones.
Bones serve various functions, such as providing support, protection, and enabling movement.
