Foramen cecum (tongue)

The foramen cecum (foramen caecum or foramen Morgagni) is a depression on the upper surface of the tongue that marks the end of the median sulcus. The median sulcus is the groove that divides the tongue into two symmetrical halves. The foramen cecum is about 2.5 cm from the root of the tongue and from here the terminal sulcus, runs forward, as a shallow groove in a V shape to each side of the margins of the tongue.
