At joints , two parts of skelton meet. The region at which two bones joints is called the joints of bones in body. There are different types of joints classified based on the location of these bones.
Joints are regions at which two bones meet. The kind of movement that a particular joint can do depends on its kind and qualities. Joints can be grouped according to their structure and function.
The joints allow us to swivel our neck, bend our knees and elbows, and rotate our shoulders, among other things. A joint is by definition a place where two bones come together to form a structure that enables movement. Ligaments are tissues that hold bones to one another. Tendons serve as the link between muscles and bones.
Where bones are rigid, there are fixed joints, also known as immovable joints. Bones have been joined in these joints in such a way that they are fastened to that component, usually to construct a structure. The movable joints are called cartilaginous joints.
