| simple anchorage | Anchorage in which the resistance to the movement of one or more teeth comes solely from resistance to tipping movement of the anchorage unit. (05 Mar 2000) |

| anchorage | <cell biology> Attachment, not necessarily adhesive in character, because the mechanism is not assumed the term ought to be more widely used. (18 Nov 1997) |
|---|---|
| anchorage dependence | <cell biology, cell culture> The necessity for attachment (and spreading) in order that a cell will grow and divide in culture. Loss of anchorage dependence seems to be associated with greater independence from external growth control and is probably one of the best correlates of tumourigenicity in vivo. Anchorage independence is usually detected by cloning cells in soft agarose, only anchorage independent cells will grow and divide (as they will in suspension). (18 Nov 1997) |
| reciprocal anchorage | Anchorage in which the movement of one or more teeth is balanced against the movement of one or more opposing teeth. (05 Mar 2000) |
| reinforced anchorage | Anchorage in which more than one type of resistance unit is utilised. Synonym: reinforced anchorage. (05 Mar 2000) |
| cervical anchorage | Anchorage in which the back of the neck is used for resistance by means of a cervical strap. (05 Mar 2000) |
| multiple anchorage | Anchorage in which more than one type of resistance unit is utilised. Synonym: reinforced anchorage. (05 Mar 2000) |
| stationary anchorage | Anchorage in which the resistance to the movement of one or more teeth comes from the resistance to bodily movement of the anchorage unit; a questionable concept since the selected teeth remain only relatively stable. (05 Mar 2000) |
| intermaxillary anchorage | Anchorage in which the units in one jaw are used to effect tooth movement in the other jaw. (05 Mar 2000) |
| intramaxillary anchorage | Anchorage in which the resistance units are all situated within the same jaw. (05 Mar 2000) |
| intraoral anchorage | Anchorage in which the resistance units are all located within the oral cavity. (05 Mar 2000) |
| occipital anchorage | Anchorage in which the top and back of the head are used for resistance by means of a headgear. (05 Mar 2000) |
| extraoral anchorage | Anchorage in which the resistance unit is outside the oral cavity; e.g., cranial, occipital, or cervical anchorage. (05 Mar 2000) |
| mastectomy, simple | Removal of only the breast tissue and nipple and a small portion of the overlying skin. (12 Dec 1998) |
| microscope, simple | <microscopy> A microscope that has a single converging lens (or a combination of lenses that function optically as a single converging lens). Anton van leeuwenhoek (1632-1723) made good use of the simple microscope to look at the life within a drop of water, and such. The magnifying properties of lenses had been well known in ancient times (for example to the greeks and romans) but it was not until about 1600 that it became possible to make small lenses with the precision needed to make a microscope.

| simple | Undivided, of a leaf, not divided into leaflets, of a hair or an inflorescence, not branched. (09 Oct 1997) |
