The highest point, summit, or apex of something; in anatomy, a pointed structure at the roof of the fourth ventricle in the brain.
From Latin 'fastigium,' meaning 'top' or 'apex,' possibly derived from 'fastus' (height or pride) and related to 'fascia' (the strip or band at the top of a building).
Neurologists still call part of your brain 'the fastigium'—it's a tiny apex inside your cerebellum that helps control balance and coordination, and the Romans named it perfectly 2,000 years ago!
