Fontanellene

Fontanellene is a term used in medical and veterinary contexts to describe a soft spot or depression in the skull of a newborn or young animal. It is typically found in the anterior fontanel, which is located at the front of the skull, and the posterior fontanel, which is located at the back. These fontanelles are areas where the bones of the skull have not yet fused, allowing for the passage of cerebrospinal fluid and the growth of the brain.

In human newborns, the anterior fontanel is usually closed by the age of 18 months, while the posterior fontanel may close later, around the age of 2 years. In animals, the timing of fontanel closure can vary depending on the species. Fontanelles are important for the development of the skull and brain, and their proper closure is a normal part of growth and maturation.

In some cases, a fontanel may not close as expected, which can be a sign of certain medical conditions or abnormalities. For example, in humans, failure of the anterior fontanel to close can be associated with conditions such as hydrocephalus or craniosynostosis. In animals, similar issues can indicate developmental problems or other health concerns. If a fontanel does not close or if there are concerns about its development, it is important to consult with a healthcare professional for proper evaluation and treatment.
