There are a vast quantity of joint which supports in the movement of our body such as "Socket Joints ".They're the joints which can make it possible to create a movement into various directions. These joints include a head of an extended bone such as thigh or upper arm, which will be greatly just like a ball. The joints at hips and shoulders are the right example of describing socket joints.

There is another type of joint which can be called "Hinge Joints" through which movement is possible in two directions. Human elbow and knee joints are the best exemplory case of describing Hinge Joints. Another very important kin of joints is "Pivot Joint ".This joint allows our body to produce a twisting movement. We are able to easily feel it while rotating the palm our hands upside and down.

"Sliding Joint" is another kind of joint which slides over bones including the wrist and ankle joints could be moved into various directions. There also remains "Gliding Joint", making the movement easily in a back and forth manner.

Aside from all the aforementioned joints which normally assist in movement, there's a "Fixed Joint" as well whereby movement is impossible at all, as an example the joints of skull and many more sub joints prevailing in the human skeleton.

Even though human skeleton may be the strongest part of human body but the fact of immunity from catching diseases is ignorable. Sometimes the skeleton of human becomes so weak that it results in deformation and is called Genetic Disorders. There are several causes of deformation such as GENETIC DISORDER and CLEFT PLATE which may cause deformity to the skeleton. In such a situation the palatine processes of maxilla and palatine cannot fuse and there seems to be a persistent opening found involving the oral and nasal cavity, which interferes with sucking. Such a scenario could result in inhalation of food into lung thereby causing aspiration pneumonia.

Apart from the Genetic Disorders there are also various other skeletal deformities in which joints are damaged and is called Arthritis. This could cause swelling on the joints which is quite painful and causes it to be impossible to move. The overall impact of Arthritis is really painful that it causes it to be quite impossible to move the bone as it had been moving before.

If you have a difference present in the joints of bones that can paralyze a person as an example there are many cases present in which people had minor gap between their bones which made them to linger and sometimes they're even not had the oppertunity to stand on that leg. Like the body, bones are also not immune to catching diseases.
