Cribriform plate

The cribriform plate is a sieve-like structure between the anterior cranial fossa and the nasal cavity. It is a part of ethmoid bone and supports the olfactory bulb. It is perforated by foramina for the passage of the olfactory nerves and the anterior ethmoidal nerves to the upper part of the nasal septum, the latter of those to the superior nasal concha.
