Coronal Suture - English Definition & Meaning

Definition

The coronal suture is a fibrous joint that connects the frontal bone (forehead) to the parietal bones (top of the skull). Think of it as a seam running across the top of your head, from ear to ear. It's an immovable joint, providing stability to the skull. This suture allows the skull to grow during childhood and fuses in adulthood. Unlike synovial joints, the coronal suture doesn’t allow for much movement. It's like a permanent weld holding two important skull bones together. Without it, your forehead wouldn't be securely attached to the rest of your skull.

Etymology

The word 'coronal' comes from the Latin word 'corona,' meaning 'crown' or 'wreath.' This is because the suture runs around the head like a crown. 'Suture' comes from the Latin word 'sutura,' meaning 'seam' or 'sewing together.' Therefore, 'coronal suture' refers to the 'crown-like seam' that joins the frontal and parietal bones. This term has been used in anatomy since the Renaissance.
