A cranial anatomical point located at the junction between the temporal bone and mastoid process, used in anthropometric measurements.
From Greek entomon (insect) combined with -ion (anatomical landmark suffix). The naming is obscure but may reference the pointed or cut-like appearance of this bone junction, reminiscent of insect body articulations.
The entomion is one of those quirky anatomical reference points that anthropologists use when measuring skulls—it's named for something insect-related but has nothing to do with bugs, showing how scientific naming can get hilariously disconnected from meaning!
