If certain bones of the skull grow too fast then premature fusion of the sutures, craniosynostosis, may occur. [1] This can result in skull deformities. [1] These deformities include: [3] Brachycephaly (both sides) Plagiocephaly (one side only) Oxycephaly (both sides)
The head rests on the top part of the vertebral column, with the skull joining at C1 (the first cervical vertebra known as the atlas). The skeletal section of the head and neck forms the top part of the axial skeleton and is made up of the skull, hyoid bone, auditory ossicles, and cervical spine. The skull can be further subdivided into:
Base of the skull. Upper surface. (Frontoethmoidal suture is not labeled, but is visible at top, between frontal bone in blue, and ethmoid bone in white.)
In many species, the cephalon had sutures running from back to front round the outside edges of the eyes. These sutures divided the cephalon into three pieces. The sutures in trilobites' cephalons were unusual because it seems their main function was to create weaknesses , which made it easy for this part of the carapace ("armor") to split when ...
The sutures are an essential part of growth and development, allowing the skull to expand as the brain increases in size. Different sutures between the frontal and parietal bones of the skull expand in specific directions, causing a symmetrically shaped human head. [3] The frontal bone and the parietal bones are joined at the frontal suture ...
If the suture is not present at birth because both frontal bones have fused (craniosynostosis), it will cause a keel-shaped deformity of the skull called trigonocephaly. Its presence in a fetal skull, along with other cranial sutures and fontanelles , provides a malleability to the skull that can facilitate movement of the head through the ...

The sagittal suture, also known as the interparietal suture and the sutura interparietalis, [citation needed] is a dense, fibrous connective tissue joint between the two parietal bones of the skull. The term is derived from the Latin word sagitta , meaning arrow .
