5 Building Blocks of the Human Body
206 bones of different shapes and sizes compose the adult skeleton; but did you know that as a newborn, your skeleton was composed of 300 bones? For example, a newborn’s skull has eight separate bone segments, while an adult’s skull is composed of only four. As an adult, bones have joined together leaving you with only 206 bones.
