The cribriform plate is a thin, bony structure located in the skull, specifically part of the ethmoid bone. It forms the roof of the nasal cavity and separates it from the brain. This plate contains numerous small holes, allowing the passage of olfactory nerves, which are responsible for the sense of smell. In addition to its role in olfaction, the cribriform plate is important for protecting the brain from potential infections that could arise from the nasal cavity. Damage to this area can lead to complications, including loss of smell or cerebrospinal fluid leaks.
