| apnea | <clinical sign> Cessation of breathing. (18 Nov 1997) |
|---|---|
| central apnea | Apnea as the result of medullary depression which inhibits respiratory movement. (05 Mar 2000) |
| sleep apnea | Temporary stoppage of breathing during sleep, often resulting in daytime sleepiness. (12 Dec 1998) |
| sleep apnea syndrome | <syndrome> A disorder characterised by multiple episodes of partial or complete cessation of respiration during sleep. (05 Mar 2000) |
| sleep apnea syndromes | Disorders involving apneic episodes during sleep. They may be due to cessation of diaphragmatic movement, obstruction of upper airway air flow, or a combination of these, and may be associated with hypersomnolence, insomnia, or obesity. (12 Dec 1998) |
| sleep-induced apnea | Apnea resulting from failure of the respiratory centre to stimulate adequate respiration during sleep; divided into respiratory pause (cessation of air flow for less than 10 seconds) and apneic pause (cessation of air flow greater than 10 seconds). (05 Mar 2000) |
| deglutition apnea | Inhibition of breathing during swallowing. (05 Mar 2000) |
| induced apnea | Intentional respiratory arrest during general anaesthesia produced by hypocapnia, a muscle relaxant drug, respiratory centre depression, or sudden cessation of controlled respiration. (05 Mar 2000) |
| obstructive apnea | Peripheral apnea, apnea either as the result of obstruction of the air passages or inadequate respiratory muscle activity. (05 Mar 2000) |
| alveolar point | The most anterior point on the maxillary alveolar process in the midline. Synonym: alveolar point, prostheon. Origin: G. Ntr. Of prosthios, foremost (05 Mar 2000) |
| anterior focal point | The point where parallel rays from the retina are focused. (05 Mar 2000) |
| apophysial point | The centre of the root of the anterior nasal spine. Synonym: apophysary point, apophysial point, spinal point. (05 Mar 2000) |
| arrow point tracing | A tracing of mandibular movements made by means of a device attached to the opposing arches; its shape resembles that of an arrowhead or a Gothic arch, and when the instrument's marking point is at the apex of the arch, the jaws are considered to be in centric relation. Synonym: arrow point tracing, Gothic arch tracing, Gothic arch, stylus tracing. (05 Mar 2000) |
| auricular point | A craniometric point at the centre of the opening of the external acoustic meatus; or, in certain cases, the middle of the upper edge of this opening. Synonym: auricular point. Origin: L. Auricularis, pertaining to the ear (05 Mar 2000) |
| axial point | One of two point's in a compound optical system so related that a ray directed toward the first point will appear to have passed through the second point parallel to its original direction. Synonym: axial point. (05 Mar 2000) |
