The Terminal sulcus of tongue is an organ found on the dorsal surface of the tongue in the oral cavity. The dorsum of the tongue is convex and marked by a median sulcus, which divides it into symmetrical halves; this sulcus ends about 2.5 cm. from the root of the organ, in a depression called the foramen cecum, from which a shallow groove, the terminal sulcus, runs laterally and forward on either side to the margin of the tongue. This sulcus divides the tongue into pharyngeal and oral parts. The pharyngeal part is supplied by glossopharyngeal nerve and the oral part is supplied by the lingual nerve (a branch of the mandibular branch (V3) of the trigeminal nerve) for somatosensory perception and by the chorda tympani (a branch of the facial nerve) for taste perception. ==Additional Images== File:Slide8sss.JPG|Terminal sulcus of tongue File:Slide5ttt.JPG|Terminal sulcus of tongue File:Slide11uuu.JPG|Terminal sulcus of tongue File:Slide1kaka.JPG|Floor of mouth.
