| horizontal growth phase | An early stage of development of cutaneous melanoma by intraepidermal spread of atypical melanocytes. (05 Mar 2000) |
|---|---|
| horizontal osteotomy | An osteotomy performed intraorally for genioplasty; the inferior aspect of the anterior mandible is advanced or retruded by movement of the free segment. (05 Mar 2000) |
| horizontal overlap | The projection of the upper anterior and/or posterior teeth beyond their antagonists in a horizontal direction. Synonym: overjet, overjut. (05 Mar 2000) |
| horizontal part of duodenum | pars horizontalis duodeni, inferior part of duodenum, pars inferior duodeni |
| horizontal plane | A plane across the body at right angles to the coronal and sagittal plane's. Synonym: horizontal plane. (05 Mar 2000) |
| horizontal plate of palatine bone | The part of the palatine bone that forms the posterior part (approximately one third) of the bony palate. Synonym: lamina horizontalis ossis palatini. (05 Mar 2000) |
| horizontal resorption | A progressive loss of alveolar and supporting bone surrounding the teeth, beginning at the most coronal level of the bone. Synonym: horizontal resorption. (05 Mar 2000) |
| horizontal survey | <epidemiology> A study of a community, perhaps stratified by age, sex, ethnicity etc., but at one point in time or over a short time interval. Although a snapshot, horizontal surveys of prevalence and intensity within different age classes of a community can nevertheless provide valuable information on the rate at which hosts acquire infection through time, provided that the host and parasite populations have remained approximately stable for a period of time (i.e. Stable endemicity). Same as cross-sectional study , converse of longitudinal study. (05 Dec 1998) |
| horizontal transmission | <epidemiology> Transmission occurring generally within a population, but not including vertical transmission. (05 Dec 1998) |
| horizontal vertigo | Dizziness experienced on lying down. (05 Mar 2000) |
| disease transmission, horizontal | The transmission of infectious disease or pathogens from one individual to another in the same generation. (12 Dec 1998) |
| transverse horizontal axis | An imaginary line around which the mandible may rotate through the horizontal plane. Synonym: hinge axis, mandibular axis. (05 Mar 2000) |
| Frankfort horizontal plane | A standard craniometric reference plane passing through the right and left porion and the left orbitale; drawn on the profile radiograph or photograph from the superior margin of the acoustic meatus to the orbitale. Synonym: auriculo-infraorbital plane, eye-ear plane, Frankfort horizontal plane, Frankfort plane, infraorbitomeatal plane. (05 Mar 2000) |
| abdominal canal | A passage in the lower anterior abdominal wall which in the male allows passage of the spermatic cord and in the female contains the round ligament. Because of the weakness it creates in the abdominal wall, it is the most frequent site for a hernia. (12 Dec 1998) |
| accessory canal | A channel leading from the root pulp laterally through the dentin to the periodontal tissue; may be found anywhere in the tooth root, but is more common in the apical third of the root. Synonym: lateral canal. (05 Mar 2000) |
