| 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.

| 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) |
| yellow soft paraffin | <pharmacology> A semisolid unctuous substance, neutral, and without taste or odour, derived from petroleum by distilling off the lighter portions and purifying the residue. It is a yellowish, fatlike mass, transparent in thin layers, and somewhat fluorescent. It is used as a bland protective dressing, and as a substitute for fatty materials in ointments. Petrolatum is the official name for the purified product. Cosmoline and vaseline are commercial names for substances essentially the same, but differing slightly in appearance and consistency or fusibility. Source: Websters Dictionary (01 Mar 1998) |
| 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) |
| avian leukaemia-sarcoma complex | A term applied to a group of transmissible virus-induced diseases of chickens causing sarcoma, myeloblastosis, erythroblastosis, leukosis, osteopetrosis, and lymphomatosis. These agents are closely related viruses (avian leukosis-sarcoma virus) causing prolferation of immature erythroid, myeloid, or lymphoid cells, a division of the RNA tumour viruses (subfamily Oncovirinae) causing the avian leukosis-sarcoma complex of diseases; the viruses are subgrouped according to antigenic characteristics and growth in defined types of tissue culture cells. Synonym: avian erythroblastosis virus, avian leukosis-sarcoma virus, avian lymphomatosis virus, avian myeloblastosis virus, avian sarcoma virus, fowl erythroblastosis virus, fowl lymphomatosis virus, fowl myeloblastosis virus.

| avian leukosis-sarcoma virus | avian leukosis-sarcoma complex |
| avian sarcoma | <tumour> A fibrosarcoma, originally observed in a Plymouth Rock hen, now thought to be an expression of infection by certain viruses of the avian leukosis-sarcoma complex in the family Retroviridae. Synonym: avian sarcoma, Rous tumour. (05 Mar 2000) |
| avian sarcoma virus | avian leukosis-sarcoma complex |
| botryoid sarcoma | <tumour> A polypoid form of embryonal rhabdomyosarcoma which occurs in children, most frequently in the urogenital tract, characterised by the formation of grossly apparent grapelike clusters of neoplastic tissue that consist of rhabdomyoblasts, spindle, and stellate cells in a myxomatous stroma; neoplasms of this type grow relatively rapidly and are highly malignant.

| giant cell monstrocellular sarcoma of Zulch | A histologic form of glioblastoma with large, often multinucleated, bizarre, tumour cells. Synonym: giant cell monstrocellular sarcoma of Zulch. (05 Mar 2000) |
