|---|---|
| Isapt | spatial peak, temporal average intensity [pulse] |
| Isata | spatial average, temporal average intensity [pulse] |
| ITA | inferior temporal artery; internal thoracic artery; International Tuberculosis Association |
| Ita | temporal average intensity [pulse] |
| superior temporal line | The upper of two curved lines on the parietal bone; the temporal fascia is attached to it. Synonym: linea temporalis superior, temporal ridge. (05 Mar 2000) |
|---|---|
| superior temporal sulcus | The longitudinal sulcus that separates the superior and middle temporal gyri. Synonym: sulcus temporalis superior, superior temporal fissure. (05 Mar 2000) |
| superior temporal venule of retina | The venule that passes from the upper lateral (temporal) part of the retina to join the central vein. Synonym: venula temporalis retinae superior. (05 Mar 2000) |
| superior branch of the superior gluteal artery | <anatomy, artery> Runs between gluteus medius and minimus muscles, supplying both, and continuing to reach tensor fascia lata muscle. Synonym: ramus superior arteriae gluteae superioris. (05 Mar 2000) |
| superior dental branches of superior dental plexus | Branches passing from the superior dental plexus to the roots of the teeth of the upper jaw. Synonym: rami dentales superiores plexus dentalis superioris. (05 Mar 2000) |
| superior gingival branches of superior dental plexus | Branches of superior dental plexus to gingiva of upper jaw. Synonym: rami gingivales superiores plexus dentalis superioris. (05 Mar 2000) |
| superior lingular branch of lingular branch of superior lobar left pulmonary artery | <anatomy, artery> Branch (of the lingular branch) of the left pulmonary artery serving the superior lingular segment of the superior lobe of the left lung. Synonym: ramus lingularis superior. (05 Mar 2000) |
| all-trans-retinal | The orange retinaldehyde resulting from the action of light on the rhodopsin of the retina, which converts the 11-cis-retinal component of the rhodopsin to all-trans-retinal plus opsin. Synonym: trans-retinal, visual yellow. (05 Mar 2000) |
| blood-retinal barrier | Specialised nonfenestrated tightly-joined endothelial cells that form a transport barrier for certain substances between the retinal capillaries and the retinal tissue. (12 Dec 1998) |
| central retinal artery occlusion | <ophthalmology> The sudden blockage of the retinal artery with a blood clot that commonly leads to a painless but irreversible blindness in that eye. (12 Jan 1998) |
| central retinal fovea | A depression in the centre of the macula retinae containing only cones and lacking blood vessels. Synonym: fovea centralis retinae, central pit. (05 Mar 2000) |
| central retinal vein occlusion | <ophthalmology> The sudden blockage of the retinal vein with blood clot that commonly leads to a painless irreversible blindness in that eye. (12 Jan 1998) |
| retinal | 1. <anatomy> Pertaining to the retina. 2. <biochemistry> The aldehyde of retinol, derived by the oxidative enzymatic splitting of absorbed dietary carotene and having vitamin A activity. In the retina, retinal combines with opsins to form visual pigments. One isomer, 11 cis retinal combines with opsin in the rods (scotopsin) to form rhodopsin or visual purple. Another, all trans retinal (trans r.), visual yellow, xanthopsin) results from the bleaching of rhodopsin by light, in which the 11 cis form is converted to the all trans form. Retinal also combines with opsins in the cones (photopsins) to form the three pigments responsible for colour vision. (18 Nov 1997) |
| retinal adaptation | Adjustment to degree of illumination. (05 Mar 2000) |
| retinal anlage tumour | A benign neoplasm of neuroectodermal origin that most often involves the anterior maxilla of infants in the first year of life. It presents clinically as a rapidly growing blue-black lesion producing a destructive radiolucency; histologically, it is characterised by small round undifferentiated tumour cells interspersed with larger polyhedral melanin-producing cells arranged in an alveolar configuration. Synonym: melanoameloblastoma, pigmented ameloblastoma, pigmented epulis, progonoma of jaw, retinal anlage tumour. (05 Mar 2000) |
