define fontanels, significance, and location

An infant is born with two major soft spots on the top of the head called fontanels. These soft spots are spaces between the bones of the skull where bone formation isn't complete. This allows the skull to be molded during birth. The smaller spot at the back usually closes by age 2 to 3 months.

what are sutures?

fibrous joints that connect the various bones of the cranium (skull)

what is the purpose of openings within the cranium?

serve as passageways for nerves, blood vessels, and other structures to pass between the internal and external parts of the head and neck, essentially allowing communication between the brain and the rest of the body
