| chorda dorsalis | <embryology> An axial mesodermal tissue found in embryonic stages of all chordates and protochordates, often regressing as maturity is approached. Typically a rod shaped mass of vacuolated cells. It lies immediately below the nerve cord and may provide mechanical strength to the embryo. (13 Nov 1997) |
| chorda magna | See: Tendon, Achilles (12 Dec 1998) |
| chorda obliqua | A slender band extending from the lateral part of the coronoid process of the ulna distad and laterad to the radius immediately distal to the bicipital tuberosity. Synonym: chorda obliqua, oblique cord, round ligament of elbow joint, Weitbrecht's cord, Weitbrecht's ligament. (05 Mar 2000) |
| chorda saliva | The secretion of the submaxillary gland obtained by stimulation of the chorda tympani nerve. (05 Mar 2000) |
| chorda spermatica | A group of structures which go through the inguinal canal to the testis. The structures include the vas deferens, arteries, veins, lymphatic vessels, and nerves. (12 Dec 1998) |
| chorda spinalis | <anatomy> Elongated, approximately cylindrical part of the central nervous system of vertebrates that lies in the vertebral canal and from which the spinal nerves emerge. (18 Nov 1997) |
| chorda tympani nerve | <anatomy, nerve> A branch of the facial (7th cranial) nerve which passes through the middle ear and continues through the petrotympanic fissure. The chorda tympani nerve carries taste sensation from the anterior two-thirds of the tongue and conveys parasympathetic efferents to the salivary glands. (12 Dec 1998) |
| chorda umbilicalis | The flexible structure, giving passage to the umbilical arteries and vein, which connects the embryo or foetus to the placenta. (12 Dec 1998) |
| chorda vertebralis | An obsolete term for notochord. (05 Mar 2000) |
| chorda vocalis | One of Ferrein's cords; the sharp edge of a fold of mucous membrane overlying the vocal ligament and stretching along either wall of the larynx from the angle between the laminae of the thyroid cartilage to the vocal process of the arytenoid cartilage; the vocal folds are the agents concerned in voice production. Synonym: plica vocalis, chorda vocalis, labium vocale, true vocal cord, vocal cord, vocal shelf. (05 Mar 2000) |
| chorda-mesoderm | That part of the protoderm of a young embryo which has the potentiality of forming notochord and mesoderm. (05 Mar 2000) |
| chordae tendineae | Thread-like bands of fibrous tissue which attach on one end to the edges of the tricuspid and mitral valves and on the other to the papillary muscles. (12 Dec 1998) |
| chordae willisii | Several fibrous cord's crossing the superior sagittal sinus. Synonym: chordae willisii. (05 Mar 2000) |
| chordal | Relating to any chorda or cord, especially to the notochord. (05 Mar 2000) |
| anterior canaliculus of chorda tympani | <anatomy> A canal in the petrotympanic or glaserian fissure, near its posterior edge, through which the chorda tympani nerve issues from the skull. Synonym: Civinini's canal, Huguier's canal, iter chordae anterius. (05 Mar 2000) |
|---|---|
| ramus communicans cum chorda tympani | <anatomy, nerve> Terminal branch of chorda tympani joining the lingual nerve in the infratemporal fossa; conveys sensory fibres for taste from anterior two-thirds of tongue and presynaptic parasympathetic fibres destined for submandibular ganglion for innervation of submandibular and sublingual salivary glands. Synonym: ramus communicans cum chorda tympani. (05 Mar 2000) |
| communicating branch of chorda tympani to lingual nerve | <anatomy, nerve> Terminal branch of chorda tympani joining the lingual nerve in the infratemporal fossa; conveys sensory fibres for taste from anterior two-thirds of tongue and presynaptic parasympathetic fibres destined for submandibular ganglion for innervation of submandibular and sublingual salivary glands. Synonym: ramus communicans cum chorda tympani. (05 Mar 2000) |
| communicating branch of otic ganglion to chorda tympani | A small branch of the otic ganglion conveying sensory fibres to the chorda tympani. Synonym: ramus communicans cum chorda tympani. (05 Mar 2000) |
| posterior canaliculus of chorda tympani | A canal leading from the facial canal to the tympanic cavity through which the chorda tympani nerve enters this cavity. Synonym: canaliculus chordae tympani, iter chordae posterius, small canal of chorda tympani. (05 Mar 2000) |
| small canal of chorda tympani | A canal leading from the facial canal to the tympanic cavity through which the chorda tympani nerve enters this cavity. Synonym: canaliculus chordae tympani, iter chordae posterius, small canal of chorda tympani. (05 Mar 2000) |
| tympanic opening of canaliculi for chorda tympani | The small canal opening found lateral to the pyramidal eminence in the posterior wall of the middle ear cavity from which the chorda tympani nerve emerges to pass anteriorly between the ossicles accompanied by a branch of the stylomastoid artery. Synonym: apertura tympanica canaliculi chordae tympani. (05 Mar 2000) |
| fold of chorda tympani | The fold of mucosa that surrounds the chorda tympani nerve in its course through the tympanic cavity. Synonym: plica chordae tympani. (05 Mar 2000) |
