Skull Sutures and Bony Plates in Fetuses and Infants

Picture of skull sutures and bony plates in fetuses and infants

The skull consists of five thin, curved, bony plates that are held together by fibrous material called sutures. These sutures allow a baby's skull to expand with the growing brain. The sutures gradually harden to join the skull bones together. The spaces where sutures meet are called soft spots or fontanelles.
