How can you explain that there are different types of bone connection in the human skeleton?

The human skeleton is made up of bones that can connect to each other in a variety of ways. The movable joint of bones is called a joint. Tendons and muscles are attached to it, with the help of which a person can make conscious movements. Movable joints are essential for a person to move. Fixed joints of bones can be formed by connective tissue, cartilage, bone or elastic. They are necessary in the case when the mobility of the bones is not needed, but it is necessary to keep them in a certain position, for example, to protect the internal organs. So, the bones of the skull are connected by bone tissue motionlessly, for better protection of the brain.
