There are 200-400 joints in the human body. The answer to your question varies on the resource used. Factors that influence the answer are definition and age. A short explanation as to how each factor influences the answer is provided below.

  1. Definition

Resources vary in the following three key points:

- Whether or not joints that produce little movement, such as skull sutures, are included in the total count.

- Whether or not co-dependent joints are considered to be one joint.

-  How individual variations, such as floating ribs, are accounted for.

 2. Age

Over time, some bones fuse together. An example would be the hip bone. Prior to puberty, the hip bone is made of the ilium bone, pubis bone, and ischium bone. Whether or not the area where these bones once came together is counted in the sum of total human joints is debatable.
