The inion is the most prominent projection of the occipital bone at the posterioinferior (lower rear) part of the skull. The ligamentum nuchae and trapezius muscle attach to it.
The term external occipital protuberance (protuberantia occipitalis externa) is sometimes used as a synonym, but more precisely the term "inion" refers to the highest point of the external occipital protuberance.
History
The word "inion" is the Greek word for the occipital bone.
