surface
| articular surface of acromion | A small oval facet on the medial border of the acromion for articulation with the lateral end of the clavicle. Synonym: facies articularis acromii. (05 Mar 2000) |
|---|---|
| articular surface of arytenoid cartilage | The oval surface on the undersurface of the muscular process of the arytenoid for articulation with the cricoid cartilage. Synonym: facies articularis cartilaginis arytenoideae. (05 Mar 2000) |
| articular surface of head of fibula | The flat circular surface on the head of the fibula for articulation with the corresponding facet on the lateral condyle of the tibia. Synonym: facies articularis capitis fibulae. (05 Mar 2000) |
| articular surface of head of rib | An articular surface on the head of a rib that articulates with the body of a vertebra. Synonym: facies articularis capitis costae. (05 Mar 2000) |
| articular surface of patella | The posterior surface of the patella, covered with hyaline cartilage and subdivided by a vertical ridge into a larger lateral and a smaller medial surface for articulation with the corresponding condyles of the femur. Synonym: facies articularis patellae. (05 Mar 2000) |
| articular surface of temporal bone | The smooth portion of the mandibular articular fossa and eminence of the temporal bone that articulates with the disk of the temporomandibular joint. Synonym: facies articularis ossis temporalis. (05 Mar 2000) |
| articular surface of tubercle of rib | An oval facet on the inferomedial part of the tubercle of a rib for articulation with a facet on the transverse process of a vertebra. Synonym: facies articularis tuberculi costae. (05 Mar 2000) |
| arytenoidal articular surface of cricoid | One of two oval facets on the superiorelateral margin of the cricoid lamina for articulation with the arytenoid cartilages. Synonym: facies articularis arytenoidea cricoideae. (05 Mar 2000) |
| auricular surface of ilium | The irregular, L-shaped articular surface on the medial aspect of the ilium that articulates with the sacrum. Synonym: facies auricularis ossis ilii. (05 Mar 2000) |
| auricular surface of sacrum | The rough articular surface on the lateral aspect of the sacrum that articulates with the ilium on each side. Synonym: facies auricularis ossis sacri. (05 Mar 2000) |
| axial surface | The surface of a tooth parallel with its long axis; the axial surface's are the vestibular (labial or buccal), lingual, and contact (mesial or distal). (05 Mar 2000) |
| balancing occlusal surface | The contact's between upper and lower dentures on the balancing or mediotrusive side for the purpose of stabilizing the dentures, the contact's between upper and lower dentures at the opposite side from the working or laterotrusive side (anteroposteriorly or laterally) for the purpose of stabilizing the dentures, the contact's between upper and lower natural or artificial teeth at the opposite side from the working or laterotrusive side. Synonym: balancing occlusal surface. (05 Mar 2000) |
| basal surface | The surface of the denture of which the detail is determined by the impression and which rests upon the basal seat. (05 Mar 2000) |
| body surface potential mapping | Recording of regional electrophysiological information by analysis of surface potentials to give a complete picture of the effects of the currents from the heart on the body surface. It has been applied to the diagnosis of old inferior myocardial infarction, localization of the bypass pathway in wolff-parkinson-white syndrome, recognition of ventricular hypertrophy, estimation of the size of a myocardial infarct, and the effects of different interventions designed to reduce infarct size. The limiting factor at present is the complexity of the recording and analysis, which requires 100 or more electrodes, sophisticated instrumentation, and dedicated personnel. (12 Dec 1998) |
| buccal surface | The mucosa of the cheek, in prosthodontics, the side of a denture adjacent to the cheek. Synonym: vestibular surface of tooth. (05 Mar 2000) |
