| 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) |
| 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) |
| antecubital space | The fossa in front of the elbow, bounded laterally and medially by the humeral origins of the extensors and flexors of the forearm, respectively, and superiorly by an imaginary line connecting the humeral condyles. Synonym: fossa cubitalis, antecubital space, chelidon, triangle of elbow. (05 Mar 2000) |
| anterior clear space | On lateral chest radiographs, the region dorsal to the sternum and ventral to the ascending aorta. Synonym: anterior clear space. (05 Mar 2000) |
| apical space | The space between the alveolar wall and the apex of the root of a tooth where an alveolar abscess usually has its origin. (05 Mar 2000) |
| axillary space | <anatomy> The underarm area. (16 Dec 1997) |
| Berger's space | The space between the patellar fossa of the vitreous and the lens. (05 Mar 2000) |
| Bogros' space | A triangular space between the peritoneum and the transversalis fascia, at the lower angle of which is the inguinal ligament; it contains the lower portion of the external iliac artery. Synonym: Bogros' space, spatium retroinguinale. (05 Mar 2000) |
