The nasion is a prominent landmark on the human skull located at the intersection of the frontal bone and the nasal bones. It serves as a crucial reference point in craniofacial measurements and anatomical studies. The nasion marks the starting point of the nasal bridge and plays a role in determining facial proportions and symmetry. Additionally, it serves as a point of attachment for certain muscles and ligaments involved in facial expression and movement. The precise location of the nasion can vary among individuals and is of interest in various fields, including anthropology, forensic sciences, and plastic surgery.
