The skull doesn't actually have any joints. The spaces between the bones of the cranium are call sutures. They're there because when a human is born the bones are separated to allow rapid growth of the brain and skull. As the person ages, the bones become fused together to create an entirely unified skull. The skulls of elderly people barely show the lines of the sutures at all, which comes in handy sometimes when determining the age of a dead body.
Your right, the joint in your skull are immovable...except your jaw. If you dis-assembled your skull you would find the lower jaw removes quite easily.
It's like why does your body work so easily? It all comes down to the muscels. In your jaw you have many muscels but one paritcular is called the mandibular joint. This is the point of which your lower jaw is connected to the top jaw. Movement of the mouth all depends on the lower jaw. Try it....open and close your mouth....your top jaw never moves.

The bones in the skull and the bones in the sacrum come to mind . . .
The "sutures" are fibrous (immovable) joints between the plates of the skull, which must expand apart with age.
Humans have fixed joints in their craniums. That means they are immovable. They were once not completely fused together in order for the infant to get through the birth canal, but now they form one complete shell over your brain for protection. save the scarecrows
The most common example of immovable joints are found in the sutures of the adult skull. The teeth in their sockets form immovable joints as well. The growth plates of children's long bones are immovable joints. The joint between the first rib and the breastbone is also an immovable joint.
Immovable joints in the skull would affect the brain. If the brain moved around due to these immovable parts, then people would have brain damage.
immovable
Fibrous Joints are also known as immovable joints. An example of these are Cranial Joints found in the skull.
A fibrous joint, also known as a synarthrosis, is essentially immovable. These joints are held together by fibrous connective tissue, such as sutures in the skull, and allow for very limited to no movement.
synarthrotic joints are immovable such as the bones of the skull.
Immovable joints, also known as synarthroses, cannot move. These joints are characterized by a lack of joint cavity and dense connective tissue binding the bones together. The most common examples of immovable joints are the sutures in the skull, which allow for the growth of the skull during childhood but fuse and become immobile in adulthood.
An immovable joint is one that doesn't allow any movement. There are several mainly in the skull. There are 22 bones in the skull that have these joints.
The bones in the skull and the bones in the sacrum come to mind . . .
A fibrous joint is an immovable joint. An example would be the bones in the skull.
The joints between bones of the skull are immovable and called sutures.
The skull has a number of immovable joints. These are seen between the plates of the skull. A good example of a pivot joint is a joint between the first two vertebrae: C1 and C2.
The bones of the skull when they fuse in an adult form an immovable joint.
