Skeletal sutures are immovable joints found between the bones of the skull. These sutures allow the skull to grow during infancy and childhood, but eventually fuse together in adulthood to form a single, solid structure. The main types of sutures in the skull are the sagittal suture, coronal suture, lambdoid suture, and squamous suture.
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.

Cranial sutures typically fuse completely by early adulthood, around the age of 25. However, this can vary between individuals. Cranial sutures allow the bones of the skull to grow and expand during infancy and childhood.
In an open wound usually after a day the wound needs to be opened or cleaned from recent coagulation for sutures to be effective.
The skull joints, known as cranial sutures, are most remembered for their intricate patterns of attachment between the bones of the skull. These sutures allow for slight movement during childbirth and head growth in infants, while becoming more rigid in adulthood to provide structural stability to the skull.
The short answer is yes. Sutures are used to hold skin or parts of your body together. When they are used internally, they can be absorbable or non-absorbable sutures. Non-absorbable sutures can be left in the body for a number of reasons and usually to hold something together for life, like a vasectomy, and as the name suggest absorbable sutures will absorbe into your body over time and never need removing.
When the sutures of the skull are no longer visible, it often indicates that the bones of the skull have fused together, typically occurring in adulthood. This fusion is a natural process called cranial ossification, which helps provide stability and protection to the brain.
A progressive condition, usually beginning in adulthood.
The metopic suture is a type of skull suture that is not always present in the adult population. It connects the two halves of the frontal bone and usually fuses by the age of 6, but it can persist into adulthood in some individuals, or fail to form altogether.
