They allow for overlapping of skull bones during birth to reduce the fetal head diameter, permit brain growth as the brain expands rapidly in the early years after birth, and the anterior fontanelle typically closes around 2 years of age.
2. Hematopoietic stem cells in red bone marrow have the ability to differentiate into various blood cell types like red blood cells, white blood cells, and platelets.
