| crista galli |
the dorsal continuation of the perpendicular plate of the ethmoid. The crista galli can be envisioned as a thin sheet of bone oriented straight up and down. It splits the ethmoid in two lengthwise and rises into the brain where it may partially separate the hemispheres of the mammalian brain.
