Quizplus · Accepted Answer

The anterior and posterior fontanelles are soft spots on a newborn's skull that allow for brain growth and can be used to assess the newborn's hydration status and general health after birth. The anterior fontanelle is larger and closes later (around 18-24 months) compared to the posterior fontanelle, which usually closes by 1-2 months of age. They are not the same size, do not both close within 12 months, and are not used to identify station in labor.
