Examine the fetal skeleton and skull (figs. 14.8 and 14.9). The skull is incompletely developed and the cranial bones are separated by fibrous membranes. These membranous areas are called fontanels, or "soft spots." The fontanels close as the cranial bones grow together. The posterior and lateral fontanels usually close during the first year after birth, whereas the anterior fontanel may not close until the middle or end of the second year. What other features characterize the fetal skull?

Identify the correct statement regarding fontanelles. A) The occipital fontanelles are also known as the soft spot. B) The sphenoidal fontanelles are the largest. C) They enable easier delivery through the birth canal. D) They persist throughout childhood. E) They form fibrous connections between facial bones.
To facilitate the process of birth, an infant’s head is somewhat flexible. This flexibility is due in part to the two fontanelles, which are so spots of connective tissue in the infant’s skull. With time, the fontanelles will close through a process known as: (A) endochondral ossification. (B) intramembranous ossification. (C) bone resorption. (D) longitudinal growth.
