What is the function of the cribriform plate?

The cribriform plate is a thin, bony structure located in the skull that forms part of the ethmoid bone. Its primary function is to support the olfactory bulb and allow for the passage of olfactory nerves, which are responsible for the sense of smell. The numerous small holes in the cribriform plate enable these nerves to extend from the nasal cavity to the brain, facilitating the transmission of scent information. Additionally, it plays a role in separating the nasal cavity from the cranial cavity.
