Canonical: https://factsreef.com/fact-checks/everyday/how-many-bones-are-in-the-human-body-9e81b3 Asked as: "how many bones do we have in our body" ## The short answer **How many bones do we have in our body? Adults usually have 206 bones.** The number is lower than at birth because many bones fuse as we grow, and some references count a few small bones differently. [1][2][4][5] ## Key facts - **An adult human skeleton is usually counted as 206 bones.** StatPearls, Johns Hopkins Medicine, MedlinePlus, the NIH, and OpenStax all give 206 as the standard adult total. [1][2][3][6][8] - **Babies are born with more bones than adults.** Common sources say about **270** or **300** at birth, because many separate bones later fuse together. [1][4][5] - **The adult skeleton is usually divided into 80 axial bones and 126 appendicular bones, for a total of 206.** [6] - **Some sources give a range of 206 to 213 bones in adults.** That range reflects normal variation and different counting rules, especially for ribs, vertebrae, sesamoid bones, and other small structures. [5][7] - **Teeth are not counted as bones in the standard 206-bone total.** Johns Hopkins notes that the 206 does not include teeth or small sesamoid bones in tendons. [2] ## Why the usual answer is 206 If someone asks for the number of bones in the human body, the standard textbook answer is **206 for an adult**. StatPearls says, “**The adult human skeleton is composed of 206 bones**,” and Johns Hopkins Medicine gives the same total. MedlinePlus and the NIH curriculum materials also use 206 as the adult count. [1][2][3][8] That total is a convention, not a magic number. It is the count most often used in anatomy classes and medical references because it gives a stable way to describe the adult skeleton. OpenStax breaks that adult skeleton into **80 axial bones** and **126 appendicular bones**, which adds up neatly to **206**. [6] ## Why babies have more bones Newborns do not start with 206 bones. Their skeleton begins with many separate pieces that later merge. StatPearls says there are approximately **270 bones at birth**, while NIAMS says a baby is born with about **300 bones** and many of them fuse to form the adult skeleton. Cleveland Clinic gives the same basic picture, noting that babies are usually born with **270 bones** that grow together over time. [1][4][5] This happens because some parts of the skeleton are made from multiple pieces early in life. As a child grows, those pieces fuse into larger bones. That is why the skull, pelvis, spine, and other areas can be counted differently at different ages or under different counting rules. [1][4][7] ## Why some books say 206 to 213 Not every source agrees on exactly 206 because the answer depends on **what counts as a bone**. Johns Hopkins explicitly says the 206 total does **not** include teeth or small bones called sesamoids, and Cleveland Clinic notes that adults can have **206 to 213 bones** because some people have different numbers of ribs or spinal bones. [2][5] A 2020 review in *Clinical Anatomy* also explains that the modern 206-bone total depends on several assumptions: whether teeth are excluded, whether sesamoid bones are counted, and how the skull, sacrum, coccyx, and sternum are treated. The authors write that “**difficulties in establishing a definitive bone count**” come from individual differences and inconsistent counting methods. [7] So the best plain-English answer is this: **206 is the standard adult count, but the real number can vary a little from person to person.** That is why a careful source may say “usually 206” or “206 to 213” instead of claiming every adult has exactly the same number. [1][5][7] ## The simplest way to answer the question For everyday use, say **“An adult human body has 206 bones.”** If you want to be more precise, add that **babies are born with about 270 to 300 bones, and some bones fuse as they grow.** If you want to be most careful of all, say **“Adults usually have 206 bones, though the exact count can vary slightly.”** [1][4][5][7] That version covers the standard classroom answer and the reason experts sometimes qualify it. It also avoids the common mistake of counting teeth or tiny sesamoid bones as part of the 206. [2][5] ## Frequently asked questions ### Do teeth count as bones? **No.** Teeth are hard, mineralized structures, but they are not counted in the standard adult skeleton total of 206 bones. Johns Hopkins Medicine specifically says the 206-bone count does not include teeth or sesamoid bones. [2] ### Why do babies have more bones than adults? **Because many of their bones have not fused yet.** Newborns start with separate bone pieces that later join together during growth. Sources commonly give birth counts of about 270 or about 300, depending on how the skeleton is counted. [1][4][5] ### Is the number exactly 206 for every adult? **No.** 206 is the standard adult count, but some adults have a slightly different total because of normal anatomical variation and different counting methods. Cleveland Clinic gives a range of **206 to 213** bones in adults. [5][7] ### How are the bones divided in the adult skeleton? **The adult skeleton is usually divided into 80 axial bones and 126 appendicular bones.** The axial skeleton includes the skull, spine, ribs, and sternum, while the appendicular skeleton includes the limbs and the bones that attach them to the body. Together, they make 206. [6] ## Sources 1. [Physiology, Bone - StatPearls - NCBI Bookshelf](https://www.ncbi.nlm.nih.gov/books/NBK441968/) — NCBI Bookshelf 2.
