The bregma is known as the anterior fontanelle during infancy. The anterior fontanelle is membranous and closes in the first 18-36months of life (according to Thieme atlas of anatomy).
The bregma is often used as a reference point for stereotactic surgery of the brain.
Also, examination of an infant includes palpating the anterior fontanelle. A sunken fontanelle indicates dehydration, whereas a very tense or bulging anterior fontanelle indicates raised intracranial pressure.
Bregma comes from the Greek bregma, meaning top of the head.
