SutureS
What sort of joint does the skull have?
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.
What function do immovable joints in the skull?
They are not joints - they are called 'Sutures'. (soo-chers) In the unborn infant, the sutures are loose and can move around a bit. This helps the infant's head exit the mother's body when it is born. The loose sutures also allow for the baby's head to grow. When the skull is as big as it is going to get, the sutures start growing a little more bone, and they attach to each other solidly. In adulthood, the sutures have no use - they are simply left over from childhood.
How many sutures are in the skull?
There are eight sutures in the human skull. These sutures are fibrous joints that connect the bones of the cranium and allow for slight movement during childbirth and growth. Some examples of skull sutures include the sagittal suture, coronal suture, and lambdoid suture.
What fuses the bones of the skull?
The bones of the skull are fused by sutures that form important anatomical landmarks. Sutures are joints that run jaggedly along the interface between the bones.
What is an inmoveable joint?
One that does not move. The sutures that join the bones in the skull are examples of immovable joints.
Is it just ball and socket joints which are synovial?
No. Typically any joint that is freely movable is synovial. Joints that do not move, like the sutures of the skull, are not synovial.
What kind of movement does synarthrotic joints allow?
Synarthrotic joints allow for minimal to no movement. They are immovable or allow very limited movement and provide stability and support to the body. Examples include the joints between the skull bones (sutures).
What do you call the immovable joints in the skull?
The bones of the skull when they fuse in an adult form an immovable joint.
