Question:

Describe and discuss how a newborn skull develops

Author: Nontoe Nonoe



Answer:

-Flat bones of the newborn skull are separated by connective tissue at the regions where the cranial sutures will eventually form - The reason for these soft tissue inserts between the bones is to allow for moulding of the skull during birth so that it can fit through the birth canal. -In some areas, these connective tissue regions form diamond- or triangle-shaped spaces called fontanelles -There are six of these on a newborn skull, and they ossify at relatively predictable times after birth -The most famous of these frontanelles is the bregma which is found at the intersection b/n the sagitaal and coronal sutures.This is commonly known as the soft spot and closes about 18 months after birth. Sutures remain membranous sometime after birth so as to allow flat bones to expand a little as the brain undergoes rapid postnatal growth
