It is traversed by the frontoethmoidal, sphenoethmoidal, and sphenofrontal sutures.
Its lateral portions roof in the orbital cavities and support the frontal lobes of the cerebrum; they are convex and marked by depressions for the brain convolutions, and grooves for branches of the meningeal vessels.

The central portion corresponds with the roof of the nasal cavity, and is markedly depressed on either side of the crista galli. The nasal cavity (or nasal fossa) is a large air-filled space above and behind the nose in the middle of the face. ...

It presents, in and near the median line, from before backward, the commencement of the frontal crest for the attachment of the falx cerebri; the foramen cecum, between the frontal bone and the crista galli of the ethmoid, which usually transmits a small vein from the nasal cavity to the superior sagittal sinus; behind the foramen cecum, the crista galli, the free margin of which affords attachment to the falx cerebri; on either side of the crista galli, the olfactory groove formed by the cribriform plate, which supports the olfactory bulb and presents foramina for the transmission of the olfactory nerves, and in front a slit-like opening for the nasociliary nerve. The falx cerebri (Latin: scythe of the brain) is an extension of the protective dura mater that projects into the longitudinal fissure that seperates the two cerebral hemispheres. ...

The Ophthalmic nerve is one of the three branches of the trigeminal nerve, one of the cranial nerves. ...
Lateral to either olfactory groove are the internal openings of the anterior and posterior ethmoidal foramina; the anterior, situated about the middle of the lateral margin of the olfactory groove, transmits the anterior ethmoidal vessels and the nasociliary nerve; the nerve runs in a groove along the lateral edge of the cribriform plate to the slit-like opening above mentioned; the posterior ethmoidal foramen opens at the back part of this margin under cover of the projecting lamina of the sphenoid, and transmits the posterior ethmoidal vessels and nerve.
Farther back in the middle line is the ethmoidal spine, bounded behind by a slight elevation separating two shallow longitudinal grooves which support the olfactory lobes.
Behind this is the anterior margin of the chiasmatic groove, running lateralward on either side to the upper margin of the optic foramen.
