| metastatic spread | <oncology> Process of development of secondary tumours. Involves local invasion (in most cases), passive transport, lodgement and proliferation at a remote site. (18 Nov 1997) |
| point-spread function | <microscopy> The mathematical representation of the image of a point source. For a diffraction-limited optical system operating in the absence of aberrations, the point-spread function is the Airy disk. See: three-dimensional diffraction pattern. (05 Aug 1998) |
| spread | 1. To extend in length and breadth, or in breadth only; to stretch or expand to a broad or broader surface or extent; to open; to unfurl; as, to spread a carpet; to spread a tent or a sail.

| line spread function | A measure of the ability of a system to form sharp images; in radiology, determined by measuring the spatial density distribution on film of the X-ray image of a narrow slit in a dense metal, such as uranium; from this can be calculated the modulation transfer function. (05 Mar 2000) |
| carotid artery, common | The two principal arteries supplying the structures of the head and neck. They ascend in the neck, one on each side, and at the level of the upper border of the thyroid cartilage, each divides into two branches, the external (carotid artery, external) and internal (carotid artery, internal) carotid arteries.

| migraine, common | Migraine without aura. The most frequent type, accounting for about 80-85% of migraines. See migraine. (12 Dec 1998) |
| cold, common | A viral upper respiratory tract infection. A contagious illness caused by a number of different types of viruses. Because of the great number of viruses that can cause a cold, the body never builds up resistance (immune) against all of them. For this reason, colds are a frequent and recurring problem. In fact, preschool children average 9 colds a year; those in kindergarten, 12 colds a year; and adolescents and adults, 7 colds per year. Going out into the cold weather has no effect on the spread of a cold. Antibiotics do not help the common cold. (12 Dec 1998) |
| common acute lymphoblastic leukaemia | <haematology, oncology> A sub-type of acute lymphoblastic leukaemia affecting cells early in the B lymphocyte lineage which accounts for about 80% of all acute lymphoblastic leukaemia. Origin: Gr. Haima = blood (13 Nov 1997) |
| common antigen | Cross reacting antigen (epitope), a common antigen that occurs in 2 or more different molecules/organisms. Synonym: heterogenic enterobacterial antigen. (05 Mar 2000) |
| common baldness | Hair loss in women that may be associated with aging, hormones (androgens) or genetic predisposition. The pattern of baldness in women is different from that of men. In women there is thinning of the hair all over the scalp, but the frontal hairline is maintained. The hair loss is usually permanent. Treatment has been successful with topical minoxidil in some cases. (27 Sep 1997) |
| common basal vein | <anatomy, vein> The tributary to the inferior pulmonary vein (right and left) that receives blood from the superior and inferior basal veins. Synonym: vena basalis communis. (05 Mar 2000) |
| common bile duct | <anatomy> A duct that carries bile from the liver and gallbladder to the duodenum (first part of the small intestine). (27 Sep 1997) |
| common bile duct calculi | The presence of gallstones in the common bile duct. It is usually the result of passage of gallstones formed in the gallbladder into the common duct. Less commonly, stones form in a duct behind an obstruction caused by a stricture or ampullary stenosis. Stone type helps to determine site of origin: cholesterol or black pigment stones more likely form in the gallbladder, while almost all brown pigment stones in patients from western countries form in the bile ducts.
