| 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.

| reticular formation | <anatomy, neurology> A region extending from the pons & medulla oblongata through the mesencephalon, characterised by a diversity of neurons of various sizes and shapes, arranged in different aggregations and enmeshed in a complicated fibre network. (12 Dec 1998) |
| personality formation | The life history associated with the development of individual patterns and of one's individuality. (05 Mar 2000) |
| rosette formation | The in vitro formation of clusters consisting of a cell (usually a lymphocyte) surrounded by antigenic cells or antigen-bearing particles (usually erythrocytes, which may or may not be coated with antibody or antibody and complement). The rosette-forming cell may be an antibody-forming cell, a memory cell, a T-cell, a cell bearing surface cytophilic antibodies, or a monocyte possessing fc receptors. Rosette formation can be used to identify specific populations of these cells. (12 Dec 1998) |
| rouleaux formation | The arrangement of red blood cells in fluid blood (or in diluted suspensions) with their biconcave surfaces in apposition, thereby forming groups that resemble stacks of coins. Synonym: false agglutination, pseudoagglutination. Origin: Fr. Pl. Of rouleau, a roll (05 Mar 2000) |
| concept formation | A cognitive process involving the formation of ideas generalised from the knowledge of qualities, aspects, and relations of objects. (12 Dec 1998) |
| heat of formation | The heat (expressed in calories or joules) absorbed or liberated during the (hypothetical) reaction in which a mole of a compound is formed from the necessary elements, in elemental form. (05 Mar 2000) |
| symptom formation | An unconscious psychological process by which a repressed impulse is indirectly manifested through a particular symptom, e.g., anxiety, compulsion, depression, hallucination, obsession. Synonym: symptom formation. (05 Mar 2000) |
| enthalpy of formation | <chemistry> The enthalpy change when 1 mole of a substance is formed from the elements in their standard states, represented by the symbol Hf. Synonym: heat of formation. (09 Jan 1998) |
| formation | 1. The act of giving form or shape to anything; a forming; a shaping. 2. The manner in which a thing is formed; structure; construction; conformation; form; as, the peculiar formation of the heart. 3. A substance formed or deposited. 4. <geology> Mineral deposits and rock masses designated with reference to their origin; as, the siliceous formation about geysers; alluvial formations; marine formations. A group of beds of the same age or period; as, the Eocene formation. 5. The arrangement of a body of troops, as in a square, column, etc. Origin: L. Formatio: cf. F. Formation.

| argyrophilic fibre | Reticular connective tissue fibre's that react with silver salts and appear black microscopically. (05 Mar 2000) |
| bowel disorders and fibre | High fibre diets help delay the progression of diverticulosis and, at least, reduce the bouts of diverticulitis. In many cases, it helps reduce the symptoms of the Irritable Bowel Syndrome ( IBS ). It is generally accepted that a diet high in fibre is protective, or at least reduces the incidence, of colon polyps and colon cancer. (12 Dec 1998) |
