| middle superior alveolar branch of infraorbital nerve | <anatomy, nerve> The middle superior alveolar branch, a branch of the superior alveolar nerve that contributes to the superior dental plexus. Synonym: ramus alveolaris superior medius nervi infraorbitalis. (05 Mar 2000) |
|---|---|
| minimal alveolar concentration | The end-alveolar concentration of an inhalation anaesthetic which prevents somatic response to a painful stimulus in 50% of individuals; an index of relative potency of inhalation anaesthetics. Synonym: minimal anaesthetic concentration. (05 Mar 2000) |
| crest of alveolar ridge | The top of the alveolar ridge or residual ridge; the highest continuous surface of the ridge, but not necessarily the centre of the ridge. (05 Mar 2000) |
| posterior alveolar artery | <anatomy, artery> Origin, 3rd part of maxillary artery within pterygopalatine fossa; distribution, molar and premolar teeth, gingiva and mucous membrane of maxillary sinus. Synonym: arteria alveolaris superior posterior, posterior alveolar artery, posterior dental artery. (05 Mar 2000) |
| posterior superior alveolar artery | <anatomy, artery> Origin, 3rd part of maxillary artery within pterygopalatine fossa; distribution, molar and premolar teeth, gingiva and mucous membrane of maxillary sinus. Synonym: arteria alveolaris superior posterior, posterior alveolar artery, posterior dental artery. (05 Mar 2000) |
| posterior superior alveolar branches of maxillary nerve | <anatomy, nerve> The branches of the superior alveolar nerves that supply the maxillary sinus and the molar tooth. Synonym: rami alveolares superiores posteriores nervi maxillaris. (05 Mar 2000) |
| sarcoma, alveolar soft part | A variety of sarcoma having a reticulated fibrous stroma enclosing groups of sarcoma cells, which resemble epithelial cells and are enclosed in alveoli walled with connective tissue. It is a rare tumour, usually occurring between 15 and 35 years of age. It appears in the muscles of the extremities in adults and most commonly in the head and neck region of children. Though slow-growing, it commonly metastasizes to the lungs, brain, bones, and lymph nodes. (12 Dec 1998) |
| segmental alveolar osteotomy | An intraoral surgical procedure in which segments of alveolar bone containing teeth are sectioned between, and apically to, the teeth for the repositioning of the alveolus and teeth; it may be maxillary or mandibular, and may be combined with ostectomy. (05 Mar 2000) |
| pulmonary alveolar proteinosis | <radiology> Overproduction of surfactant which can lead to alveolar (end-air-space) filling, peak age: 20 - 50 yrs, 33% asymptomatic, treatment: lavage Findings: bat-wing alveolar infiltrate, no interstitial disease, no adenopathy (12 Dec 1998) |
| squamous alveolar cells | Highly attentuated squamous cell's that form the gas-permeable epithelium lining the alveoli of the lungs. Synonym: type I cells. (05 Mar 2000) |
| superior alveolar nerves | Three branches (posterior, middle, and anterior) of the maxillary nerve (or its continuation as the infraorbital nerve) that enter the maxilla to supply the mucosa of the maxillary sinus, upper teeth and gingiva. Synonym: nervi alveolares superiores, superior dental nerves. (05 Mar 2000) |
| ideal alveolar gas | The uniform composition of gas that would exist in all alveoli for a given total respiratory exchange if all alveoli had identical ventilation-perfusion ratios and achieved perfect equilibrium with the blood leaving the pulmonary capillaries. (05 Mar 2000) |
| inferior alveolar artery | <anatomy, artery> Origin, 1st part of maxillary artery; distribution, through mandibular foramen/canal to lower teeth and chin; branches, artery to mylohyoid, mental artery, dental arteries. Synonym: arteria alveolaris inferior, inferior dental artery. (05 Mar 2000) |
| inferior alveolar nerve | <anatomy, nerve> One of the terminal branches of the mandibular, it enters the mandibular canal to be distributed to the lower teeth, periosteum, and gingiva of the mandible; a branch, the mental nerve, passes through the mental foramen to supply the skin and mucosa of the lower lip and chin. Synonym: nervus alveolaris inferior, inferior dental nerve. (05 Mar 2000) |
| intra-alveolar septa | The bony partitions that project into the alveoli between the roots of the molar teeth. Synonym: septa interradicularia, intra-alveolar septa. (05 Mar 2000) |
