In brief: Yes, but...

Yes, but nature is not perfect, and humans are not completely symmetric.
The inion is the bump that sticks out at the lower rear part of the human skull. The ligamentum nuchae and trapezius muscle attach to it. The term "external occipital protuberance" is sometimes used as a synonym for "inion", but some say "inion" means the highest point of the external occipital protuberance.
