CORONAL SUTURE Meaning and
Definition
-
The coronal suture refers to a fibrous joint found in the human skull, specifically between the frontal and parietal bones. It is classified as a synarthrosis, which means it is an immovable joint that provides stability and support to the skull.
The coronal suture can be identified as a line of articulation that extends horizontally across the skull, from one side to the other, separating the frontal bone (also known as the forehead bone) from the parietal bones (located near the sides and top of the skull). This joint is notably visible on the exterior of the head.
During development, the coronal suture acts as a growth plate, allowing the skull to expand and accommodate the developing brain. However, as a person reaches adulthood, the suture generally becomes ossified, meaning it solidifies and fuses the frontal and parietal bones together.
An important anatomical landmark, the coronal suture helps experts identify and study skulls, particularly in forensic science, archeology, and anthropology. Its alignment, shape, and closure can provide valuable information about an individual's age, sex, and ancestry. Additionally, abnormalities or premature fusion of the coronal suture may indicate certain medical conditions or craniofacial deformities.

Etymology of CORONAL SUTURE
The word "coronal suture" has its origin in Latin.
1. "Coronal" comes from the Latin word "corona", which means "crown" or "garland". In anatomy, the term "coronal" refers to a front-to-back plane that is perpendicular to the sagittal plane, dividing the body into front and back portions.
2. "Suture" comes from the Latin word "sutura", which means "seam" or "stitch". In anatomy, a suture refers to the line where two bones meet and grow together, forming an immovable joint.
Therefore, the term "coronal suture" refers to the suture that separates the frontal bone and the parietal bones of the skull, resembling a crown-like seam or line.
