| microplania | Decreased horizontal diameter of erythrocytes. Origin: micro-+ L. Planus, flat (05 Mar 2000) |
|---|---|
| microplasia | Stunted growth, as in dwarfism. Origin: micro-+ G. Plasis, a shaping, forming (05 Mar 2000) |
| microplasmodesmata | Fine pores occuring in the septa of certain filamentous prokaryotes, such as actinomycetes and cyanobacterial trichomes. These pores are used for communication (exchange of metabolites) between two adjacent cells which are separated by septa. (09 Oct 1997) |
| microplethysmography | The technique of measuring minute changes in the volume of a part as a result of blood flow into or out of it. (05 Mar 2000) |
| micropodia | Abnormal smallness of the feet. Origin: micro-+ G. Pous, foot (05 Mar 2000) |
| micropore | An organelle formed by the pellicle of all stages of sporozoan protozoa of the subphylum Apicomplexa and also found in developmental stages that may lack the inner pellicle layer; it is composed of two concentric rings (in transverse section), the inner of which corresponds with an invagination of the outer pellicle membrane. Micorpores thus far observed seem to serve as feeding organelles; their role in nonfeeding developmental forms is unknown. Origin: micro-+ G. Poros, pore (05 Mar 2000) |
| micropore filter | A filter made of a meshwork of cellulose acetate or nitrate and with defined pore size. They can be autoclaved and the smaller pore sizes (0.22m,0.45m) are used for sterilising heat labile materials by filtering out micro organisms. Larger pore size filters are used in setting up Boyden chambers. They are about 150m thick and should be distinguished from Nucleopore filters. Millipore is a trade name for micropore filters. (18 Nov 1997) |
| microprecipitation test | A precipitation test in which reduced quantities of test reagents are used. (05 Mar 2000) |
| microprobe | A technique of elemental analysis in the electron microscope based on spectral analysis of the scattered X-ray emission from the specimen induced by the electron beam. Using this technique it is possible to obtain quantitative data on, for example: the calcium concentration in different parts of a cell, but it is necessary to use ultra thin frozen sections. (18 Nov 1997) |
| micropromyelocyte | A cell derived from a promyelocyte. (05 Mar 2000) |
| micropropagation | The use of biotechnological methods to grow large numbers of plants from very small pieces of plants, often from single cells using tissue culture methods. (14 Nov 1997) |
| microprosopia | A condition characterised by an abnormally small or imperfectly developed face. Origin: micro-+ G. Prosopon, face (05 Mar 2000) |
| micropsia | Perception of objects as smaller than they are. Origin: micro-+ G. Opsis, sight (05 Mar 2000) |
| micropuncture | A puncture made with the aid of a microscope. (05 Mar 2000) |
| micropyle | 1. Small hole or aperture in the protective tissue surrounding a plant ovule, through which the pollen tube enters at fertilization. Develops into a small hole in the seed coat through which, in many cases water enters at germination. 2. Perforation in the shell (chorion) of an insect egg through which the sperm enters at fertilization. (18 Nov 1997) |
| microns |
A measure of length; the thousandth part of one millimeter; the millionth part of a meter.

| microsporidiosis |
an intestinal infection that causes diarrhea and wasting in people with HIV. It results from two different species of microsporidia, a protozoal parasite. Two common organisms that cause it are Enterocytozoon and Septata. Among the possible treatments are THALIDOMIDE and ALBENDAZOLE.

(Gr. mikros, small; glia, glue): Small supporting cells of the central nervous system (neuroglia) derived from the mesoderm (blood histiocytes) and having a phagocytic function.
