| traction alopecia | Circumscribed or diffuse loss of hair resulting from repetitive traction on the hair by pulling or twisting; also occurs after excessive application of hair "softeners" such as permanent wave solutions or hot combs. Alopecia marginalis is a form of traction alopecia. Synonym: traumatic alopecia. (05 Mar 2000) |

| lipedematous alopecia | Alopecia with itching, soreness, or tenderness of the scalp in adult negro women; the scalp is thickened and soft, subcutaneous fat is increased, and the hair is sparse and short. (05 Mar 2000) |
| airspace-filling pattern | Cloudy to dense opacities, obscuring vascular markings, on chest radiographs. Synonym: airspace-filling pattern. (05 Mar 2000) |
| airway pattern | Chest radiographic appearance of thickened bronchial walls, bronchiectasis, bronchiolitis, or acinar consolidation. (05 Mar 2000) |
| alveolar pattern | Cloudy to dense opacities, obscuring vascular markings, on chest radiographs. Synonym: airspace-filling pattern. (05 Mar 2000) |
| A-pattern strabismus | Strabismus in which esotropia is more marked in looking upward than downward, strabismus in which exotropia is more marked on looking downward than upward. Synonym: A-pattern strabismus. (05 Mar 2000) |
| axial pattern flap | A flap that includes a direct specific artery within its longitudinal axis. Synonym: arterial flap. (05 Mar 2000) |
| ballerina-foot pattern | A vigorous posteromedial contraction of the left ventricle coupled with convexity anteriorly sometimes resulting from poor contraction of the opposing anterior wall; it is the most frequent dyssynergy observed in the prolapsed mitral valve leaflet syndrome (even with a normal anterior wall) and produces a configuration of angiographic dye in the right anterior oblique projection resembling a ballerina's foot; sometimes called dancer's foot malformation. (05 Mar 2000) |
| banding pattern | <genetics> Chromosomes stained with certain dyes, commonly quinacrine (Q banding) or Giemsa (G banding), show a pattern of transverse bands of light and heavy staining that is characteristic for the individual chromosome. The basis of the differential staining, which is the same in most tissues, is not understood: each band represents 5-10% of the length, about 10exp7 base pairs, although this is not true for polytene chromosomes in Drosophila that show more than 4000 bands.

| butterfly pattern | Bilateral, symmetric, pulmonary alveolar opacities sparing the periphery, on chest radiographs; usually caused by pulmonary oedema. (05 Mar 2000) |
| random pattern flap | A flap in which the pedicle blood supply is derived randomly from the network of vessels in the area, rather than from a single longitudinal artery as in an axial pattern flap. (05 Mar 2000) |
| pattern | 1. Anything proposed for imitation; an archetype; an exemplar; that which is to be, or is worthy to be, copied or imitated; as, a pattern of a machine. "I will be the pattern of all patience." (Shak) 2. A part showing the figure or quality of the whole; a specimen; a sample; an example; an instance. "He compares the pattern with the whole piece." (Swift) 3. Stuff sufficient for a garment; as, a dress pattern. 4. Figure or style of decoration; design; as, wall paper of a beautiful pattern. 5. Something made after a model; a copy. "The patterns of things in the heavens." (Heb. Ix. 23) 6. Anything cut or formed to serve as a guide to cutting or forming objects; as, a dressmaker's pattern. 7. A full-sized model around which a mold of sand is made, to receive the melted metal. It is usually made of wood and in several parts, so as to be removed from the mold without injuring it. A definable characteristic relationship between the members of any set of objects or actions; also, the set having a definable relationship between its members. Thus: the distribution of bomb or shell impacts on a target area, or of bullet holes in a target; a set of traits or actions that appear to be consistent throughout the members of a group or over time within a group, as behavioral pattern, traffic pattern, dress pattern Pattern box, chain, or cylinder, devices, in a loom, for presenting several shuttles to the picker in the proper succession for forming the figure. Pattern card. A set of samples on a card. A count-wheel. Origin: OE. Patron, F. Patron, a patron, also, a pattern. See Patron. Source: Websters Dictionary (01 Mar 1998) |
| pattern formation | <cell biology> One of the classic problems in developmental biology is the way in which complex patterns are formed from an apparently uniform field of cells. Various hypotheses have been put forward and there is now evidence for the existence of gradients of diffusible substances (morphogens) specifying the differentiative pathway that should be followed according to the concentration of the morphogen around the cell.

| pattern recognition | In information retrieval, machine-sensing or identification of visible patterns (shapes, forms, and configurations). (harrod's librarians' glossary, 7th ed) (12 Dec 1998) |
| pattern recognition, visual | Visually perceived characters, shapes, displays, or designs. (12 Dec 1998) |
