| digital 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) |
| 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) |
| 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) |
| palmar crease | Any of the several flexion crease's normally found on the palm of the hand, occurring proximal to, but as a consequence of flexion at, the metacarpophalangeal joints. (05 Mar 2000) |
| crease | A line or linear depression as produced by a fold. See: fold, groove, line. (05 Mar 2000) |
| crease wound | A tangential wound that makes a furrow without perforating the skin. Synonym: crease wound, glancing wound. (05 Mar 2000) |
| simian crease | A single palmar crease associated with Down's syndrome. (27 Sep 1997) |
| Sydney crease | A variation of the proximal transverse palmar flexion crease that reaches the ulnar side of the palm; associated with acute lymphocytic anaemia in early childhood, rubella embryopathy, and Down's syndrome. Synonym: Sydney line. (05 Mar 2000) |
| ear lobe crease | A diagonal crease found on one or both earlobes with a possible connection to coronary heart disease in males. (05 Mar 2000) |
| analog-digital conversion | The process of converting analog data such as continually measured voltage to discrete, digital form. (12 Dec 1998) |
| angiography, digital subtraction | A method of delineating blood vessels by subtracting a tissue background image from an image of tissue plus intravascular contrast material that attenuates the X-ray photons. The background image is determined from a digitised image taken a few moments before injection of the contrast material. The resulting angiogram is a high-contrast image of the vessel. This subtraction technique allows extraction of a high-intensity signal from the superimposed background information. The image is thus the result of the differential absorption of X-rays by different tissues. (12 Dec 1998) |
