[kor´dah] (pl. chor´dae) (L.) a cord or sinew. adj., adj chor´dal.chorda mag´na Achilles tendon.chor´dae tendi´neae tendinous cords connecting the two atrioventricular valves to the appropriate papillary muscles in the heart ventricles.

Chordae tendineae of the posterior cusps of atrioventricular valves in a cross-section of the heart. From Dorland's, 2000.chorda tym´pani a nerve originating from the facial nerve, distributed to the submandibular, sublingual, and lingual glands and the anterior two-thirds of the tongue; it is a parasympathetic and special sensory nerve.chorda umbilica´lis umbilical cord.chorda voca´lis vocal cord.

chor·da tym·'pa·ni

[TA] a nerve given off from the facial nerve in the facial canal that passes through the posterior canaliculus of the chorda tympani into the tympanic cavity, crosses over the tympanic membrane and handle of the malleus, and passes out through the anterior canaliculus of the chorda tympani in the petrotympanic fissure to join the lingual branch of the mandibular nerve in the infratemporal fossa; it conveys taste sensation from the anterior two thirds of the tongue and carries parasympathetic preganglionic fibers to the submandibular ganglion, for innervation of the submandibular and sublingual salivary glands. Synonym(s): radix parasympathica ganglii submandibularis [TA], cord of tympanum, parasympathetic root of submandibular ganglion, tympanichord
