Sphenoidal Crest Description
The sphenoidal crest (crest of sphenoid bone) is the vertical ridge found along the midline on the anterior surface of the body of sphenoid bone. The sphenoidal crest:
—is continuous superiorly with the ethmoidal spine and continuous inferiorly with the sphenoidal rostrum;
—is located medial to both the right and left sphenoidal conchae;
—contributes to the formation of the nasal septum;
—articulates with the perpendicular plate of the ethmoid bone, contributing to the formation of the sphenoethmoidal suture.
