If the anterior fontanel closes before 6 months of age, it may indicate conditions such as craniosynostosis, where the skull bones fuse too early, potentially leading to increased intracranial pressure and other developmental issues. Early closure can also limit the brain's growth and development. It's important for pediatricians to monitor the child's development closely and possibly conduct imaging studies to assess the skull and brain. Consulting a specialist may be necessary for appropriate management.

What are the four fontanels of an infant?
The four fontanels of an infant are the anterior fontanel, posterior fontanel, sphenoid fontanel, and mastoid fontanel. The anterior fontanel, located at the top of the head, is the largest and typically closes by 18-24 months. The posterior fontanel, situated at the back of the head, generally closes by 2-3 months. The sphenoid and mastoid fontanels are smaller and close within the first year of life.
When do babies fontanel close?
Babies have two main fontanels, the anterior and posterior. The posterior fontanel typically closes between 2 to 3 months of age, while the larger anterior fontanel usually closes by 18 months, although it can take up to 24 months for some children. These soft spots allow for the growth of the baby's brain and skull during early development. Regular pediatric check-ups help monitor their closure and overall development.
What is it fate in a fontanel?
"Fate" in the context of a fontanel refers to the future development and closure of the soft spots on an infant's skull, known as fontanels. These areas allow for brain growth and skull flexibility during childbirth. Typically, the anterior fontanel closes between 12 to 18 months of age, while the posterior fontanel usually closes by 2 to 3 months. The fate of a fontanel can indicate the health and development of a child, as abnormal closure patterns may suggest medical concerns.
What fontanel closes last?
The fontanel that closes last is the anterior fontanel, also known as the soft spot on the top of a baby's head. It typically remains open until the child is about 18 to 24 months old, allowing for brain growth and development during that period. The closure timing can vary among individuals, but this is the general timeframe for most children.
What are the type of fontanels?
There are several types of fontanels in an infant's skull, with the major ones being the anterior, posterior, sphenoidal, and mastoid fontanels. The anterior fontanel, located at the top of the head, is the largest and typically closes between 12 to 18 months. The posterior fontanel, found at the back of the skull, usually closes by 2 to 3 months. The sphenoidal and mastoid fontanels are smaller and close even earlier, contributing to the flexibility and growth of the skull during infancy.
What is the fate of a fontanel?
Fontanelle or Fontanel is the soft spot of an infant human skull between the cranial bones. The posterior fontanel closes on the first few months of life.
Identify the age range for the closure of the anterior fontanel of the skull?
6-24 months
When does the posterior fontanel close?
This one closes fairly early, usually by the time the baby is 2 months.
Where is the posterior fontanel?
The posterior fontanel is located at the back of the head where the parietal and occipital bones meet in a newborn baby. It typically closes by the time the baby is 2 months old.
When does a baby fontanal close?
The posterior fontanal closes at 2-3 months. The anterior fontanal closes at 12-18 months.
What fontanel between the parietal and occipital bone?
The fontanel located between the parietal and occipital bones is known as the posterior fontanel. It is a soft spot on an infant's skull that typically closes within the first few months after birth. This fontanel allows for flexibility during childbirth and accommodates the rapid growth of the brain during early development.
Why are the infants skull joints moveable?
They are like this because the body, including the skull with the brain within, have to grow. Also, during birth, there are stresses that are applied to the skull and the fontanels allow flexibility. The long bones in the body also have features that allow for the same growth.
