The number of bones in the skeleton of a normal adult human is

Explanation

An adult has 206 bones, 80 in the axial skeleton and 126 in the appendicular skeleton. A newborn has roughly 300 separate bones, and the number falls as several of them fuse during growth, for example the ilium, ischium and pubis into one hip bone and the five sacral vertebrae into the sacrum. That fusion is why the infant figure is the standard distractor.
