List of bones of the human skeleton – Wikipedia
List of bones of the human skeleton The human skeleton of an adult consists of around 206 bones, depending on the counting of sternum (which may alternatively be included as the manubrium, body of sternum, and the xiphoid process). It is composed of 270 bones at the time of birth, but later decreases to 206: 80 bones in the axial skeleton and 126 bones in the appendicular skeleton. Many small accessory bones, such as sesamoid bones, are not included in this count. Introduction As a person ages, some bones fuse, a process which typically lasts until sometime within the third decade of life. Therefore, the number of bones in an individual may be evaluated differently throughout a lifetime. In addition, the bones of the skull and face are counted as separate bones, despite being fused naturally. Some reliable sesamoid bones such as the pisiform are counted, while others, such as the hallux sesamoids, are not. Individuals may have more or fewer bones than the average…

How Many Bones Are There in the Human Body? – Mental Floss
How Many Bones Are There in the Human Body?If you’re taking a grade-school science quiz, competing on Jeopardy!, or playing pub trivia, the answer to a question about the number of bones in the human body is probably 206. (Or, in Jeopardy!’s case, “What is 206?”)But the notion that every person has a tidy 206 bones is sort of a misconception. For one thing, it only applies to adults. Babies are born with somewhere in the range of 270 to 300 bones, some of which are made completely of cartilage. As a baby grows, a bunch of bones fuse together and calcify, decreasing their total bone count. Infants, for example, typically have 33 vertebrae, compared to 24 for adults. And your upper arm bone—the humerus—used to have three to four parts.It understandably takes years to complete this process. According to Popular Science, most of your bones have settled into their final form around puberty. But certain ones keep growing well past that point; you might be in your mid-twenties before your clavicle calls it quits.That’s not to mention…
