Studying is an important part of academic success. However, it is sometimes difficult to find the time to study for every subject we need to study for. One way to ensure studying success is to create a solid study schedule. Creating a study schedule, though, can be harder than we think. Not only do you have to prioritize the subjects and courses you need to study for, but you also have to juggle other responsibilities such as family, friends, and entertainment.
The posterior fontanelle usually closes by age 1 or 2 months. It may already be closed at birth. The anterior fontanelle usually closes sometime between 9 months and 18 months. The sutures and fontanelles are needed for the infant's brain growth and development.
In humans, all fontanelles are generally fused by the fifth year of life with 38% of fontanelles closed by the end of the first year and 96% of the fontanelles closed by the second year. In contrast, apes fuse the fontanelles soon after birth: in chimpanzees the anterior fontanelle is fully closed by 3 months of age. With respect to sutures, humans show a delayed pattern of ossification relative to other apes.
