Frontal suture
Frontal Suture
The Frontal Suture (pronounced: fron-tal soo-chur) is a term used in anatomy to describe a fibrous joint that separates the two halves of the frontal bone of the skull in infants and children.
Etymology
The term "Frontal Suture" is derived from the Latin words 'frons' meaning 'forehead', and 'sutura' meaning 'seam'.
Description
The Frontal Suture, also known as the Metopic Suture, runs from the top of the nose to the coronal suture, along the midline of the forehead. It is a temporary structure that usually begins to close between the second and third years of life, and is typically completely fused by the age of eight.
In some individuals, the suture can persist partially or completely into adulthood, a condition known as Metopism. This is a normal anatomical variant and is not associated with any medical conditions.
