The soft spots on a baby's head are called fontanelles. There are two of them, the larger one close to the front of the head, and a smaller one that closes soon after birth fu…rther back on the head.
two "spots" generally combine to make up the larger spot. they are the posterior fontanel and the anterior fontanel
The "soft spot" is the area on top of the head where the bones of the skull have not quite joined. During pregnancy, the skull develops sort of like a jigsaw puzzle; it's not …all one bone, but rather many bones that eventually meet and fuse. Some bones meet and fuse before the baby is born. Others fuse after birth to allow room for the brain's tremendous growth over the first year. More than 50 percent of the total growth of the head occurs in this first year of life. If all the bones fused early, there would be no room for the brain as it grows. There are often several "soft spots" present at birth, but most are so small and last for so little time, that parents are unaware of them. But by two months, only two of these spots should be present: . The smaller is the posterior fontanel, on the back part of the top of the head. It's usually difficult to find at two months of age and should be completely gone (because the bones have fused) by four months. . The anterior fontanel is the one most parents recognize as the soft spot. It's on top of the head toward the front. Four bones come together at this spot, but, because of their rounded corners, they don't quite meet. This soft spot may close as early as nine months of age or as late as two years. The average is between 12 to 14 months. So, what does it mean when the soft spot seems to have closed up early? Most of the time, it means that it is still present but is difficult to feel because a tough, fibrous cartilage membrane develops over the soft spot as it is closing. This membrane can make it difficult to determine if the soft spot is still open. However, if the soft spot does indeed close early, it could be a condition called craniosynostosis, which can cause some problems. Craniosynostosis occurs in about one in 2,500 babies and usually requires surgery. If left untreated, compression of the brain may eventually occur and the other bones of the skull become deformed as they grow. This may cause vision difficulties and significant disfigurement of the face.
These "soft spots," called fontanels, are actually made of tough but flexible cartilage. A baby's brain grows very quickly, and this flexible cartilage lets the skull expand t…o make room. If the baby doesn't have this then they have it you just dont know where it is.
Its because the brain has to form . and the plate grows there later on.
Soft spots, or fontanelles, are spaces in the skull that have not matured into bone yet. They allow the baby's brain to grow and make the skull more flexible so the baby can m…ove down the birth canal. By the time the child is 2 years old their skull will be fully developed and the soft spots will be gone.
It's called a fontanel or fontanelle and allows the baby's head to pass more easily through the birth canal.
The soft spots on a baby's head are called fontanels. There are two of them, and they usually completely close by the time the baby is 2.
It is called the fontanel.
Fontanelles. These allow for the bony plates of the baby's skull to 'flex' during birth
"Fontanelle" (sometimes spelled "fontanel".) There are actually four of them, but the anterior fontanelle (directly on top) is usually the most noticeable.
The soft spot on a baby's head closes as he or she grows. Since thehead is still developing as an infant, it will gradually come intoits own as the child grows.
There are actually two soft spots on an infant's head and they'recalled "fontanelles". The posterior fontanelle is a soft spotlocated on the back of the infant's head. The ant…erior fontanelleis a soft spot located on top of the infant's head.
