The SkullThe Skull

Bones of an Infant SkullBones of an Infant Skull

• The skull of the infant has areas in which the bone formation is incomplete, leaving “soft spots”.

• At birth these membrane filled spaces called fontanels are found between cranial bones. They are areas of fibrous connective tissue and will eventually be replaced with bone by intramembranous ossification and become sutures.

Functionally, the fontanelles enable the fetal skull to modify its size and shape as it passes through the birth canal and permit rapid growth of the brain during infancy.
