If the parts of the skull were not fixed the brain would have much less protection. The spine is partially movable, or we wouldn't be able to bend. If it were fully articulated we would need much stronger muscles to keep us upright.

How do you reattach the skull back to the spine?

It is hopeful that skull has not become detached from the spine as that person would likely be dead. The joint that attaches the spinal column to the skull is called the atlanto-occiptial joint and creates forward and backward movement (flexion and extension). There are also strong ligaments. They can all be injured and if unstable it is possible to fuse to spine to the skull using plate and screws, operating from the back of the head and neck.


What would happen if your skull bone had movable joints?

If the skull bones had movable joints, it would significantly compromise the structural integrity and protection that the skull provides for the brain. This increased mobility could lead to greater vulnerability to injuries, as the brain would be less shielded from impacts. Additionally, it would disrupt essential functions such as biting and chewing, as the skull's rigidity is crucial for proper alignment of the jaw and teeth. Overall, such a change would likely result in severe consequences for both brain safety and basic physiological functions.

Why can you move your lower jaw and not the upper jaw?

Because your upper jaw is part of your skull which is connected to your spine and your lower jaw is connected to your upper jaw by a hinge type joint that allows you to move your lower jaw so that we can eat. So therefore we cannot move our upper jaw because that would require moving our head which would move our lower jaw too.
