| palmar flexion | Turning the hand or fingers toward the palmar surface. (05 Mar 2000) |
|---|---|
| paraplegia in flexion | The fixation of the paralysed legs in a flexed posture; usually in transection of the spinal cord. (05 Mar 2000) |
| plantar flexion | Turning the foot or toes toward the plantar surface. (05 Mar 2000) |
| hip-flexion phenomenon | When a hemiplegic attempts to rise from a lying posture, the hip on the paralysed side is flexed first; the same movement takes place on lying down. (05 Mar 2000) |
| digital flexion crease | One of the grooves on the palmar surface of a finger, at the level of an interphalangeal joint. Synonym: digital flexion crease, digital furrow. (05 Mar 2000) |
| flexion | <gynaecology> A displacement of the uterus in which the organ is bent so far forward or backward that an acute angle forms between the fundus and the cervix. Origin: L. Flexio (18 Nov 1997) |
| flexion crease | A permanent crease in the skin on the flexor aspect of a movable joint. (05 Mar 2000) |
| Buck's extension | Apparatus for applying longitudinal skin traction on the leg through contact between the skin and adhesive tape; friction between the tape and skin permits application of force, which is applied through a cord over a pulley, suspending a weight; elevation of the foot of the bed allows the body to act as a counterweight. Synonym: Buck's traction. (05 Mar 2000) |
| paraplegia in extension | Paralysis of the legs, maintained in an extended position by hypertonic extensor muscles. (05 Mar 2000) |
| ridge extension | An intraoral surgical operation for deepening the labial, buccal, and/or lingual sulci; it is performed to increase the intraoral height of the alveolar ridge in order to assist denture retention. (05 Mar 2000) |
| crossed extension reflex | Extension of the contralateral hind limb when the paw of an animal is painfully stimulated or the central cut end of an afferent nerve, e.g., the peroneal, is stimulated; sometimes occurs in humans upon tapping the skin. (05 Mar 2000) |
| primer extension | A technique for determining the 5'-untranslated region of a specific mRNA molecule. Uses an oligonucleotide complementary to the known RNA sequence as a primer for cDNA synthesis via reverse transcriptase. (05 Mar 2000) |
| skeletal extension | Traction pull on a bone structure mediated through pin or wire inserted into the bone to reduce a fracture of long bones. Synonym: skeletal extension. (05 Mar 2000) |
| nail extension | An obsolete method of extension, by a weight on a nail or pin in the distal fragment of a fracture. (05 Mar 2000) |
| extension | 1. <orthopaedics> The movement by which the two elements of any jointed part are drawn away from each other. 2. <anatomy> A movement which brings the members of a limb into or toward a straight relation. Origin: L. Extensio (18 Nov 1997) |
