Palatovaginal canal
The palatovaginal canal, also known as the pharyngeal canal, is a small short canal located at the articulation of the sphenoidal process of palatine bone and the vaginal process of the body of the sphenoid bone. It is lateral to the variably present vomerovaginal canal.
It transmits the pharyngeal nerve, a branch of the maxillary division of the trigeminal nerve (CN Vb) from the pterygopalatine fossa and the pharyngeal branch of maxillary artery.
