Sutures And Fontanelles Of The Skull
The sutures meet at the fontanels the soft spots on your baby s head.
Sutures and fontanelles of the skull. It is comprised of many bones formed by intramembranous ossification which are joined together by sutures fibrous joints. Two frontal bones two parietal bones and one occipital bone these are joined by fibrous sutures which allow movement that facilitates childbirth and brain growth. Craniosynostosis craniosynostosis is a premature fusion of cranial sutures in infants that may lead to profound changes in craniofacial shape.
The sutures remain flexible during infancy allowing the skull to expand as the brain grows. It lies at the junction between the sagittal suture and lambdoid suture at birth the skull features a small posterior. The sutures and fontanelles are needed for the infant s brain growth and development.
The 2 frontal bone plates meet at the metopic suture. Growth within the craniofacial skeleton is based on two key concepts. Posterior fontanelle is triangle shaped.
Cranial sutures and fontanels. During infancy and childhood the sutures are flexible. Joints made of strong fibrous tissue cranial sutures hold the bones of your baby s skull together.
These joints fuse together in adulthood thus permitting brain growth during adolescence. 10 1055 b 0034 87894 sutures and fontanelles. These changes are a result of anatomic differences between the calvarial unit and skull base portion of the skull.
Skull contains 29 bones except for mandible ear ossicles and hyoid bone all other skull bones are joined by suture. During childbirth the flexibility of the sutures allows the bones to overlap so the baby s head can pass through the birth canal without pressing on and damaging their brain. Lateral skull joining the temporal bone to the occipital parietal and sphenoid bones on each side.
