| long palmar muscle | <anatomy, muscle> Origin, medial epicondyle of humerus; insertion, flexor retinaculum of wrist and palmar fascia; action, makes palmar fascia tense and flexes the hand and forearm; is absent about 20% of the time; when tensed, its tendon stands out sharply at the wrist and overlies the median nerve; nerve supply, median.

| long peroneal muscle | <anatomy, muscle> Origin, upper two-thirds of outer surface of fibula and lateral condyle of tibia; insertion, by tendon passing behind lateral malleolus and across sole of foot to medial cuneiform and base of first metatarsal; action, plantar flexes and everts foot; nerve supply, superficial peroneal. Synonym: musculus fibularis longus, musculus peroneus longus, long fibular muscle, long peroneal muscle. (05 Mar 2000) |
| long plantar ligament | <anatomy> A strong ligament that extends from the calcaneus to the cuboid and lateral metatarsals on the plantar aspect of the foot; part of the passive support system for maintaining the longitudinal arch of the foot. Synonym: ligamentum plantare longum. (05 Mar 2000) |
| long process of malleus | A slender spur running anteriorward from the neck of the malleus toward the petrotympanic fissure. Synonym: processus anterior mallei, Folli's process, follian process, long process of malleus, processus gracilis, processus ravii, Rau's process, Ravius' process, slender process of malleus.

| 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) |
