A fontanelle (or fontanel) (colloquially, soft spot) is an anatomical feature of the infant human skull comprising soft membranous gaps (sutures) between the cranial bones that make up the calvaria of a fetus or an infant.[1] Fontanelles allow for stretching and deformation of the neurocranium both during birth and later as the brain expands faster than the surrounding bone can grow.[2] Premature complete ossification of the sutures is called craniosynostosis.
After infancy, the anterior fontanelle is known as the bregma.
