An infant's skull is made up of 6 separate cranial (skull) bones: These bones are held together by strong, fibrous, elastic tissues called sutures. 6 They found connective tissue, blood vessels and nerve fibers present in the sutural space. It is the connective tissue, or Fasciae, that is lengthening, rather than the muscle fibers. The sphenosquamous suture (or sphenosquamosal suture) is found on both lateral sides of the skull. Craniosynostosis, defined as premature fusion or growth arrest at one or more of the cranial sutures, most commonly occurs sporadically as an isolated defect. The skull is composed of thirteen separate bones that fit together like a puzzle, but they are not fixed or fused. adult Skull/sutures. 9 Later physical findings in infants with primary craniosynostosis include stunted cranial .

The borders where these plates come together are called sutures or suture lines. They appear as intricate thin lines that mark the adherence between the bones and the growth and closure of the cranial fontanelles. The sutures allow movement of the individual bones of the skull in relationship to one another.
