The uncus is an anterior extremity of the parahippocampal gyrus. It is separated from the apex of the temporal lobe by a sulcus called the rhinal sulcus.[1] Although superficially continuous with the hippocampal gyrus, the uncus forms morphologically a part of the rhinencephalon.
An important landmark that crosses the inferior surface of the uncus is the band of Giacomini or tail of the dentate gyrus.[2]
The term comes from the Latin word uncus, meaning hook, and it was coined by Félix Vicq-d'Azyr (1748–1794).[3]
