| paries posterior vaginae | It is longer than the anterior wall and has a low ridge in the midline throughout most of its length. Synonym: paries posterior vaginae. (05 Mar 2000) |
| paries superior orbitae | Formed by the orbital plate of the frontal bone and the lesser wing of the sphenoid bone, the optic canal opens at its posterior limit; an indentation, the fossa for the lacrimal gland, is located in the anterolateral part of the roof. Synonym: paries superior orbitae, superior wall of orbit. (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) |
| apertura tympanica canaliculi chordae 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) |
| canaliculus chordae 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) |
| 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.
