The ''outer surface'' is [[wikt:concavo-convex|concavo-convex]] from above downward, convex from side to side; it is covered by the [[Procerus muscle|procerus]] and [[Nasalis muscle|nasalis]] muscles, and perforated about its center by the '''nasal foramen''', a small passageway for the transmission of a small [[vein]] from the overlying soft tissues.

The ''inner surface'' is concave from side to side, and is traversed from above downward, by a groove for the passage of a branch of the [[nasociliary nerve]].
