| long pulse | A pulse in which the impact is felt longer than usual. (05 Mar 2000) |
| long QT syndrome | <cardiology, physiology, syndrome> A syndrome characterised by history of syncopal episodes and a long qt interval, sometimes leading to sudden death due to paroxysmal ventricular arrhythmia. When associated with autosomal recessive inheritance and congenital deafness, it is called the jervell-lange nielsen syndrome. When associated with autosomal dominant inheritance and no deafness is present, it is called the romano-ward syndrome. (21 Jun 1999) |
| long radial extensor muscle of wrist | <anatomy, muscle> Origin, lateral supracondylar ridge of humerus; insertion, back of base of second metacarpal bone; action, extends and deviates wrist radialward; nerve supply, radial. Synonym: musculus extensor carpi radialis longus, long radial extensor muscle of wrist. (05 Mar 2000) |
| long saphenous nerve | <anatomy, nerve> A branch of the femoral, extending from the femoral triangle to the foot, becoming subcutaneous on the medial side of the knee; it supplies cutaneous branches to the skin of the leg and foot, by way of infrapatellar and medial crural branches. Synonym: nervus saphenus, internal saphenous nerve, long saphenous nerve. (05 Mar 2000) |
| long saphenous vein | <anatomy, vein> Formed by the union of the dorsal vein of the great toe and the dorsal venous arch of the foot, ascends in front of the medial malleolus, behind the medial condyle of the femur, and traverses the saphenois hiatus in the fascia lata to empty into the femoral vein in the upper part of the femoral triangle. Synonym: vena saphena magna, large saphenous vein, long saphenous vein. (05 Mar 2000) |
| Long's coefficient | A formula for estimating from the specific gravity of a specimen of urine the approximate amount of solids in grams per liter; the last two figures of the value for specific gravity are multiplied by 2.6. Synonym: Long's coefficient. (05 Mar 2000) |
| Long's formula | A formula for estimating from the specific gravity of a specimen of urine the approximate amount of solids in grams per liter; the last two figures of the value for specific gravity are multiplied by 2.6. Synonym: Long's coefficient. (05 Mar 2000) |
| long sight | Farsightedness or hyperopia occurs when a refractive error in which light rays entering the eye are focused behind the retina. This condition is easily corrected with corrective lenses or contact lenses. (27 Sep 1997) |
| long-sightedness | 1. The state or condition of being long-sighted; hence, sagacity; shrewdness. 2. <medicine> See Hypermetropia. Source: Websters Dictionary (01 Mar 1998) |
| long subscapular nerve | <anatomy, nerve> Arises from the posterior cord of the brachial plexus; it contains fibres from the sixth, seventh, and eighth cervical nerves and supplies the latissimus dorsi muscle. Synonym: nervus thoracodorsalis, long subscapular nerve. (05 Mar 2000) |
| long-term care | Care over an extended period, usually for a chronic condition or disability, requiring periodic, intermittent, or continuous care. (12 Dec 1998) |
| long-terminal repeat | <molecular biology> Identical DNA sequences, several hundred nucleotides long, found at either end of transposons and the proviral DNA, formed by reverse transcription of retroviral RNA. They are thought to have an essential role in integrating the transposon or provirus into the host DNA. Long terminal repeats have inverted repeats, that is, sequences close to either end are identical when read in opposite directions. In proviruses the upstream long-terminal repeat acts as a promoter and enhancer and the downstream long-terminal repeat as a polyadenylation site. Acronym: LTR (15 Nov 1997) |
| long terminal repeat sequences | Regions of the RNA genome associated with regulation, integration, and expression of retroviruses. (05 Mar 2000) |
| long-term memory | That phase of the memory process considered the permanent storehouse of information which has been registered, encoded, passed into the short-term memory, coded, rehearsed, and finally transferred and stored for future retrieval; material and information retained in LTM underlies cognitive abilities.
