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.
