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
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.
An immovable joint. (sutures joining the bones of the skull)
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.
The bones of the skull are an example of a suture joint, which is a type of fibrous joint. These joints are characterized by the interlocking edges of the bones, which are connected by dense connective tissue. Sutures allow for minimal movement, providing stability and protection for the brain. As a person ages, some sutures may fuse completely, further enhancing the rigidity of the skull.
It is a combination of two types of joints: a ginglymus (hinge joint) and an arthrodial (gliding) joint.
