The Fontanelles Most importantly allow for the human skull to pass through the birth canal and are vital in allowing the brain to grow inside the skull without increasing the intercranial pressure.

How many fontanels does a newborn have?

A newborn typically has six fontanels, which are soft spots on their skull where the sutures have not fully closed yet. These fontanels allow for the baby's head to be flexible during childbirth and to accommodate the rapid brain growth during the first few years of life.


What age do the fontanels fuse?

How might the fontanels be used to estimate intracranial pressure?

Fontanels are soft spots on a baby's skull where the bones have not yet fused. By feeling the tension or bulging of the fontanels, healthcare providers can get an indirect estimate of intracranial pressure. If the fontanels are tense and bulging, it could indicate increased intracranial pressure, while sunken fontanels may indicate dehydration or decreased intracranial pressure.

The fontanels of a baby skull made of?

The fontanels of a baby skull are made of connective tissue. They are soft spots between the skull bones that allow for some flexibility during birth and rapid brain growth in the first year of life. Over time, these fontanels close as the bones of the skull fuse together.


Why do adults have fontanels soft spots?

Fontanels, or soft spots, are spaces between the bones of an infant's skull that allow for growth and the passage through the birth canal. In adults, these soft spots have typically closed as the bones fuse together, forming a solid skull to protect the brain. However, in some cases, adults may still have remnants of fontanels due to variations in bone development, but these are usually much smaller and less pronounced. The presence of fontanels in adults is relatively rare and not a common characteristic.
