Anterior Ethmoidal Nerve

Last updated: Dec 9th, 2024

The anterior ethmoidal nerve passes through the anterior ethmoidal opening and enters the cranial cavity just above the cribriform plate of the ethmoid bone. It is a branching of the nasociliary nerve that supplies branches to the mucous membrane of the nasal cavity and finally emerges between the inferior border of the nasal bone and the side nasal cartilages as the external nasal branch.
