Answer 2

Answer:

The question of how many joints there are in the human body is a difficult one to answer because it depends on a number of variables. This includes:

The definition of joints. Some define a joint as a point where 2 bones connect. Others suggest it is a point where bones connect for the purpose of moving body parts.

The inclusion of sesamoids. Sesamoids are bones imbedded in tendons, but not connected to other bones. The patella (kneecap) is the largest sesamoid. These bones vary in number from person to person.

The age of the human. Babies start out with about 270 bones. Some of these bones fuse together during growth. Adults have about 206 named bones, with 80 in the axial skeleton and 126 in the appendicular skeleton.

In short, there’s no definite answer to this question. The estimated number is between 250 and 350.
