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.
