How Many Joints Are In The Human Body? Do You Know?


How many joints are in the human body? What are the types of joints that we have? What are joints, anyway? What significant roles do they assume in our lives? If in case you are wondering, keep on reading the rest of this post and I will share some valuable insights that you have to know.

When we were in school, for sure, we have studied the human body. We were thought about joints and bones, including the exact number that is present in the human body. Now that we are old, I don’t blame you if you already forgot about these things! This post will be a refresher!

What are Joints, In The First Place?

Before we answer the main question in this article, let us first have a look at what joints exactly are. We know that they are part of the human body, but what is exactly their purpose?

Technically speaking, joint refers to “the physical point of connection between two or more bones”. Our bones are not straight. At one point, they will be connected by a joint. They will provide the flexible connection that will be required by your bones.

Among others, joints have the main purpose of providing the mechanical support that is needed by the bones. Without it, your bones will be weak and won’t be able to withstand the rigors of physical activities.

Your bones are too rigid, and hence, they cannot move. The latter will only be possible if there is a point of connection between the bones, and this is where joints enter the picture.

How Many Joints are in the Human Body

Now, let us go to the most important part of this article. If you do your research online, you will most probably be confused with the conflicting information that you will see. Generally speaking, however, the range will be anywhere from 200 to 400 joints.

So, why is it that we do not have the same number of joints in the body? Well, there are different factors that can be attributed to this. One would be age. As you grow older, some of the bones will fuse together, and hence, will lessen the number of joints that are present in your body.

Different Types of Joints

Not all types of joints can be visible to the naked eye. Among others, the largest is the one that you can find in the knee. The femur with the tibia and fibula, or simply the upper and the lower leg.

Aside from the ones at the knee, the joints in the shoulder and ankle are also large, which is why most of us would know them.

The smallest joint in the human body, on the other hand, can be found in the middle ear.

Also, while the joints connect the bones, it should be also emphasized that not all of them are moving. For instance, those that you can find in the skull are fixed.

Joints can also be classified depending on their specific structure. For instance, there are fibrous joints. They are made from collagen fibers, like the ones that you can find in the skull.

There are also cartilaginous joints, such as those that are in the ribs and spine.The most common, on the other hand, is known as a synovial joint. There is a lining around the joint that produces synovial fluid, which, in turn, will provide the lubrication that is needed to reduce friction.


Earlier, we have discussed how many joints are in the human body and other things that you have to know about joints. If you need to be refreshed about the things we have tackled above, here is a brief summary:

  • Your joints serve as the point of connection between the bones in the body. They provide the mechanical structure that is required and will allow you to move.
  • It is hard to tell exactly how many joints you have. Generally, however, it is believed that it is anywhere from 200 to 400.
  • There are different types of joints in the body, including those that do not move. The largest joint is the one that connects the upper leg to your lower leg. The smallest, on the other hand, can be found in your middle ear.
