Question

Which of the following is NOT a characteristic of Fontanels?A they are important areas where oxygen can pass through to the developing brain in infancyB they allow the head to expand in size to accommodate the brain growth that occurs in the first two years of lifeC they allow the skull to change shape during the passage of the infant though the birth canal, and then allow the skull to regain its shape following birthD infants are usually born with six major fontanels (though he or she may have some smaller ones), all of which will ossify and become incorporated into the bones of the skull in two years or lessE they will become ossified by intramembranous ossification

Answer 1

Explanation:

Fontanel is a structure that is present in the skull of human infants and it compromises of soft membranous gaps known as sutures.

The function of the fontanels is as follows:

1. To allow stretching of the neurocranium and also allow its deformation during the rapid expansion of the brain.

2. To flex the skull of the infant so that it can easily pass through the birth canal at the time of delivery.
