The “soft spots” located at the top and back of the baby's head where the bones of the skull have not fused together. These soft areas allows for the molding of the baby's head as it passes through the birth canal and gradually disappears as the child grows older. The posterior (back of the head) fontanelle usually closes by three months of age. The anterior (top of the head) fontenelle usually closes by 12 months of age.

A relatively soft, flexible, fibrous region between two flat bones in the developing skull; also spelled fontanelle.

any membranous gap between the bones of the cranium in an infant or fetus

The space between the unjoined sections of the baby's skull that are often referred to as the "soft spot".

The soft spots found between the cranial bones of an infant's skull. These spots allow the baby's head to compress slightly during passage through the birth canal.

The soft spots on a baby's head that, during birth, enable the soft bony plates of the skull to flex, allowing the head to pass through the birth canal. Fontanels are completely hardened by a child's second birthday.

The diamond-shaped indentation on the front (and back) of the infant's skull where the unconnected bones come close to each other, but don't actually attach. This "soft spot" is lined with a tough, canvas-like material that protects the brain. The lack of bony attachment allows the skull to expand to accommodate to the rapidly-expanding young brain.

The soft spot on your baby's head, indicating the unjoined sections of the skull.

The soft spot of an infants skull where the bones of the skull have not yet grown together. When increased cranial pressure (ICP) is present the fontanel may be bulging.

One of two soft spots on a newborn's head at which the bones of the baby's still-forming skull do not yet meet. They usually close by 18 months.
