it is the only movable joint of the head. peculiarity of the joint is, joints of both sides move together.
bones taking part:
proximally- mandibular fossa of the temporal bone and articular tubercle.
distally - head of the mandible is convex. a thin layer of fibrocartilage lines mandibular fossa and head of mandible.
Between the mandibule and skull is the TMJ temporomandibular joint
Temperomandibular joint
These are sutures. It is found between the skull bones.These are immovable. However there is a hinge joint at the jaw which is freely movable.
The temporal mandibular joint is a synovial joint, meaning there is a sac containing synovial fluid between the mandible (lower jaw) and temporal bone of the skull.
The Temporomandibular Joint
The temporo-mandibular joint (TMJ).
A type of joint between the bones of the skull where the bones are held tightly together by fibrous tissue. OR thread-like material used to sew tissue together.
A fixed joint is a joint between two bones that doesn't move. A good example of this is in the skull - the skull plates don't move together or against each other, but they are connected or fused. Fixed joints are also called fused joints for this reason.
This called a suture. It is an immovable joint where two bones in the skull meet to form this joint.
The bones in the skull and the bones in the sacrum come to mind . . .
suturesutureThe part of the skull that is a example of an immovable fibrous joint would be a suture.

Where bones in your skull are fixed together.
An immovable joint. (sutures joining the bones of the skull)
it is a joint that has little or no movement
The skull, ribs, and toe bones are not connected to the knee joint.
A type of joint between the bones of the skull where the bones are held tightly together by fibrous tissue. OR thread-like material used to sew tissue together.
A fixed joint is a joint between two bones that doesn't move. A good example of this is in the skull - the skull plates don't move together or against each other, but they are connected or fused. Fixed joints are also called fused joints for this reason.
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.
A fibrous joint is an immovable joint. An example would be the bones in the skull.
This called a suture. It is an immovable joint where two bones in the skull meet to form this joint.
So many joints have little or no movement. The joints between skull bones are there, probably to allow the increase in the size of the head. No movement is needed there. Movement may be harmful there. Once the growth is complete, the bones frequently get fused there, in case of skull bones.
