Abstract:
: The frontal bone is ossified in fibrous mesenchyme from two primary centers, one near each frontal tuber. At birth the bone consists of two halves. The median suture usually disappear by about 8 years, but may persist as the metopic suture. Metopic suture present at birth between the right and left halves of the frontal bone and closes at 2-5 years of the age, but may present during adult life. The suture closure began endocranially and it spread to pericranium.
