| orbitalis muscle | <anatomy> A rudimentary nonstriated muscle, crossing the infraorbital groove and sphenomaxillary fissure, intimately united with the periosteum of the orbit. Synonym: musculus orbitalis, Muller's muscle, orbital muscle. (05 Mar 2000) |

| facies orbitalis | The surface of a bone which contributes to the walls of the orbit. The NA recognises an orbital surface on the following bones: greater wing of the sphenoid bone; the maxilla; the frontal bone; the zygomatic bone. Synonym: facies orbitalis. (05 Mar 2000) |
| fissura orbitalis inferior | A cleft between the greater wing of the sphenoid and the orbital plate of the maxilla, through which pass the maxillary division and the orbital branch of the trigeminal nerve, fibres from the pterygopalatine (Meckel's) ganglion, and the infraorbital vessels. Synonym: fissura orbitalis inferior, sphenomaxillary fissure. (05 Mar 2000) |
| fissura orbitalis superior | A cleft between the greater and the lesser wings of the sphenoid establishing a channel of communication between the middle cranial fossa and the orbit, through which pass the oculomotor and trochlear nerves, the ophthalmic division of the trigeminal nerve, the abducens nerve, and the ophthalmic veins. Synonym: fissura orbitalis superior, foramen lacerum anterius, sphenoidal fissure. (05 Mar 2000) |
| arcus palatini | See: palatoglossal arch, palatopharyngeal arch. (05 Mar 2000) |
| bursa musculi tensoris veli palatini | <anatomy> A small bursa located where the tendon of the tensor passes around the pterygoid hamulus. Synonym: bursa musculi tensoris veli palatini. (05 Mar 2000) |
| bursa of tensor veli palatini muscle | <anatomy> A small bursa located where the tendon of the tensor passes around the pterygoid hamulus. Synonym: bursa musculi tensoris veli palatini. (05 Mar 2000) |
| canales palatini minores | Canalis's located in the posterior part of the palatine bone. Synonym: canales palatini minores. (05 Mar 2000) |
| rami nasales posteriores inferiores nervi palatini majoris | <anatomy, nerve> Branches of greater palatine nerve to posterior inferior lateral wall of nasal cavity, including posterior aspect of mucosa over posterior portion of inferior nasal concha and meatus; may arise independently from pterygopalatine ganglion. Synonym: rami nasales posteriores inferiores nervi palatini majoris. (05 Mar 2000) |
| ramus pharyngeus arteriae palatini descendens | <anatomy, artery> May arise as a separate branch or as a continuation of lesser palatine artery. Synonym: ramus pharyngeus arteriae palatini descendens. (05 Mar 2000) |
| musculus levator veli palatini | <anatomy, muscle> Origin, apex of petrous portion of temporal bone and lower part of cartilaginous auditory (eustachian) tube; insertion, aponeurosis of soft palate; action, raises soft palate; through the expansion of its fleshy belly during contraction, it helps to "push" open the auditory tube; nerve supply, pharyngeal plexus (cranial root of accessory nerve). Synonym: musculus levator veli palatini, elevator muscle of soft palate, levator palati muscle, musculus levator palati, musculus petrostaphylinus. (05 Mar 2000) |
| musculus tensor veli palatini | <anatomy> Tensor muscle of soft palate, musculus tensor palati; musculus palatosalpingeus; musculus sphenosalpingostaphylinus; dilator tubae; origin, scaphoid fossa of sphenoid, cartilaginous and membranous part of auditory (eustachian) tube and spine of sphenoid; insertion, posterior border of hard palate and aponeurosis of soft palate; action, tenses the soft palate; contributes to opening of auditory tube; nerve supply, branches of trigeminal nerve through the otic ganglion. Synonym: musculus tensor veli palatini, dilator tubae, musculus palatosalpingeus, musculus sphenosalpingostaphylinus, musculus tensor palati, palatosalpingeus, tensor muscle of soft palate. (05 Mar 2000) |
| nerve of tensor veli palatini muscle | <anatomy> A branch of the mandibular nerveconveying fibres from the motor root of the trigeminal nerve which pass through the otic ganglion without synapse to supply the tensor veli palatini muscle. Synonym: nervus tensoris veli palatini. (05 Mar 2000) |
| nervi palatini minores | Usually two, these nerves emerge through the lesser palatine foramina and supply the mucosa and glands of the soft palate and uvula; they are branches of the pterygopalatine ganglion and contain postsynaptic parasympathetic and sensory fibres of the maxillary nerve. Synonym: nervi palatini minores. (05 Mar 2000) |
| nervus tensoris veli palatini | <anatomy> A branch of the mandibular nerveconveying fibres from the motor root of the trigeminal nerve which pass through the otic ganglion without synapse to supply the tensor veli palatini muscle. Synonym: nervus tensoris veli palatini. (05 Mar 2000) |
