We know that there are 206 bones in human body but we do not know how many joints are there in our body. In Islamic books, Prophet Mohammad(S) said, there are 360 joints are there in human body. How will we comment on it.
Definition of joints is not exactly specific. Believe it or not, that is a complicated question. The answer depends upon what you mean by joint. For example:
Growing bones are divided into growth centers. This creates a growth joint where bone is connected to bone known as a metaphysis. If you count this as a joint then the answer depends upon how old the person is.
Some bones come together bone-to-bone, and then fuse later in life. This can be a natural process like with bone growth but occurs late in life. The sutures of the skull are an example. These joints are called synostosis.
A similar process can occur that is pathological. That can create bone spurs and new linkages, joints, among bones.
Some bones are linked together by ligaments, creating a joint known as a syndesmosis. If you count every instance where a ligament spans between two bones, and count every ligament as a separate joining, you would have an enormous number of joints.
Most of the time when we think of joints, we are thinking about the moveable joints known as synovial joints. There are a lot of these, and not all synovial joints are mobile and not all mobile joints are synovial.
In addition, there are a variable number of bones in the body. Sesamoids, small bones inside tendons, are common but variable. The number of linkages between sesamoids and more standard bone, such as the patellofemoral joint, would be impossible to count without a careful examination of the subject involved.
There are many other types of joints in the body that I am not mentioning, and there are even named joints that do not link bone-to-bone. So, again, I have to state that the answer to your question depends upon how you want to define joint. And, once you come up with a definition you like, you will always find someone who disagrees with you.
'A'ishah (A.S.) narrated that the Prophet (PBUH) said:
"Everyone has been created with three hundred and sixty Joints. Whoever mentions Allah's greatness (says Allahu Akbar), praises Allah, extols Allah, and seeks forgiveness from Allah and removes stones from the path of the people, enjoins what is good and forbids the evil to the amount of those three hundred and sixty joints (sulama), he walks on that Day (of Judgment) having distanced himself from the Hell fire."
Just sharing what i found.
First: 147 joints in the vertebral column
25 joints between the vertebrae.
72 joints between the vertebrae and the ribs.
Second: 24 joints in the thorax
2 joints between the bones of the sternum and the thoracic cage.
18 joints between the sternum and the ribs.
2 joints between the clavicle and the scapulae (shoulder blade).
2 joints between the scapulae and the thorax.
Third: 86 joints in the upper extremity
2 joints between the scapular bones.
6 joints between the elbows.
8 joints between the wrists.
70 joints between the hand bones.
Fourth: 92 joints in the lower extremity
2 hip joints.
6 joints between the knee bones.
6 joints between the ankles.
74 joints between the feet bones.
Fifth: 11 joints in the Pelvis
4 joints between the coccyx vertebrae.
6 joints between the bones acetabulm.
1 joint of the pubic sumphysis.
Total number of joints: 360
Check the attached files for details. A newborn has 275 to 300 bones, while most adults have 206. Here’s why: As a baby grows, their smaller bones join together to create larger bones. So, the bone count and bone joint both are variable but can result in approximately same as mentioned in the Hadees
