| primitive palate | In the early embryo, the mesoderm-filled shelf, formed from the medial nasal process, that anteriorly separates the oral cavity below from the primitive nasal cavities above. Synonym: primitive palate. (05 Mar 2000) |
| secondary palate | The posterior portion of the embryonic palate, which forms from the palatal processes of the embryonic maxilla and develops into the hard palate. (05 Mar 2000) |
| soft palate | The muscular part of the roof of the mouth. The soft palate is directly behind the hard palate. It lacks bone and so is soft. (12 Dec 1998) |
| tensor muscle of soft palate | <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) |
| elevator muscle of soft palate | <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) |
| falling palate | Relaxation or elongation of the uvula. Synonym: falling palate, staphylodialysis, staphyloptosis, uvulaptosis. Origin: uvulo-+ G. Ptosis, a falling (05 Mar 2000) |
| alveolar soft part sarcoma | <tumour> A malignant tumour formed of a reticular stroma of connective tissue enclosing aggregates of large round or polygonal cells; occurs in subcutaneous and fibromuscular tissues. (05 Mar 2000) |
| ameloblastic sarcoma | <tumour> A rapidly growing, painful, destructive, radiolucent odontogenic tumour that usually arises through malignant change in the mesenchymal component of a pre-existing ameloblastic fibroma. Synonym: ameloblastic sarcoma. (05 Mar 2000) |
| angiolithic sarcoma | <tumour> A firm cellular neoplasm derived from fibrous tissue of the meninges, choroid plexus, and certain other structures associated with the brain, characterised by the formation of multiple, discrete, concentrically laminated, calcareous bodies (psammoma bodies); most of these neoplasms are histologically benign, but may lead to severe symptoms as a result of compressing the brain. Synonym: angiolithic sarcoma, sand tumour, Virchow's psammoma. (05 Mar 2000) |
