Suture (anatomy) In anatomy, a suture is a fairly rigid joint between two or more hard elements of an organism, with or without significant overlap of the elements. [1] Sutures are found in the skeletons or exoskeletons of a wide range of animals, in both invertebrates and vertebrates. Sutures are found in animals with hard parts from the ...
Suture separation can be caused by variety of factors. A common, nonthreatening cause is childbirth. The plates of a newborn’s skull may overlap and form a ridge.

The coronal suture is likely supplied by a branch of the trigeminal nerve. Development. The coronal suture is derived from the paraxial mesoderm. Clinical significance. If certain bones of the skull grow too fast then premature fusion of the sutures, craniosynostosis, may occur. This can result in skull deformities.
There are eight major bones and eight auxiliary bones of the cranium. The eight major bones of the cranium are connected by cranial sutures, which are fibrous bands of tissue that resemble seams.

Frontal suture. The frontal suture is a fibrous joint that divides the two halves of the frontal bone of the skull in infants and children. Typically, it completely fuses between three and nine months of age, with the two halves of the frontal bone being fused together.
