====== Olfactory Groove ======


{{ ::olfactorygroove.jpg?400|}}The [[olfactory]] [[groove]] formed by the [[cribriform plate]], which supports the [[olfactory bulb]] and presents foramina for the transmission of the [[olfactory nerve]]s, and in front a slit-like opening for the [[nasociliary nerve]].

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.
