| 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) |
| lateral alveolar abscess | An alveolar abscess located along the lateral root surface of a tooth. Synonym: pericemental abscess. (05 Mar 2000) |
| lower alveolar point | In craniometrics, the apex of the septum between the mandibular central incisors. Synonym: lower alveolar point. (05 Mar 2000) |
| ABC process | Purification of water or deodorization of sewage by a mixture of alum, blood, and charcoal. (05 Mar 2000) |
| accessory process | A small apophysis at the posterior part of the base of the transverse process of each of the lumbar vertebrae. Synonym: processus accessorius, accessory tubercle. (05 Mar 2000) |
| acromial process | <anatomy> The lateral triangular projection of the spine of the scapula that forms the point of the shoulder and articulates with the clavicle. (27 Sep 1997) |
| activated sludge process | <procedure> A method of treating sewage and wastewater through microbial oxidation. Sewage previously treated in settling tanks is aerated to encourage the growth of nonpathogenic aerobic microorganisms (bacteria, yeasts, moulds and protozoans) which break the organic matter down into carbon dioxide, water and simple salts. After this activated sludge is produced, the wastewater undergoes further processing through anaerobic digestion, filtering and chlorination. (29 Dec 1997) |
| adiabatic process | <chemistry> A process in which the system does not exchange heat with the surroundings. (15 Jan 1998) |
| agene process | Bleaching of flour with nitrogen trichloride (prohibited in the United States). (05 Mar 2000) |
| alar process | A small lateral expansion of the ethmoid bone from the front of the crista galli on each side that articulates with the frontal bone and forms the foramen caecum. Synonym: ala cristae galli, alar process. (05 Mar 2000) |
| anterior process of malleus | A slender spur running anteriorward from the neck of the malleus toward the petrotympanic fissure. Synonym: processus anterior mallei, Folli's process, follian process, long process of malleus, processus gracilis, processus ravii, Rau's process, Ravius' process, slender process of malleus. (05 Mar 2000) |
| apical process | The dendritic process extending from the apex of a pyramidal cell of the cerebral cortex toward the surface. Synonym: apical dendrite. (05 Mar 2000) |
