Fixed joint. When you are born, there are gaps in your skull, then they start to get put together and it becomes a fixed joint.
An immovable joint. (sutures joining the bones of the skull)
Fibrous joint
an immoable is a fixed joint such as in the skull like a sutches. some kind of joint that doesnt move.
tendon
The base of the skull has a joint called the atlanto-occipital joint. It is a gliding joint that is between the occipital condyles of the occipital bone and the first cervical vertebra (C1). This type of joint is also called a synovial joint, or a freely movable joint. Another designation is diarthrotic joint.
The jaw joint
An immovable joint. (sutures joining the bones of the skull)
The mandible is attached to the skull at the temporomandibular joint (TMJ). It allows for movements like opening and closing the mouth, chewing, and speaking.
The atlantoccipital joint which is a gliding joint, not as some people believe it to be a pivot joint. The pivot joint in this area is the atlantoaxial joint which is between C1 & C2 and doers not come into contact with the skull.
In babies the skull joint is the fontanel (fontanelle) which helps in birth due to its flexibility but in the adult the skull joint is a fixed joint or a synarthrotic joint (immovable) called a suture.
It is a combination of two types of joints: a ginglymus (hinge joint) and an arthrodial (gliding) joint.
Suture is a type of fibrous joint which only occurs in the skull (cranium). Only a tiny amount of movement is permitted at sutures, which contributes to the compliance and elasticity of the skull. On the other hand, joints are usually very flexible and can therefore move.
