| polar presentation | The presentation of either pole of the foetal oval; may be either a cephalic or breech presentation, or a longitudinal lie. (05 Mar 2000) |
|---|---|
| polar ring | A thickened, electron-dense ring at the anterior end of certain stages of the Apicomplexa; part of the apical complex characteristic of these sporozoans. (05 Mar 2000) |
| polar solvents | Solvent's that exhibit polar forces on solutes, due to high dipole moment, wide separation of charges, or tight association; e.g., water, alcohols, acids. (05 Mar 2000) |
| polar star | One of the figures forming the diaster. Synonym: polar star. (05 Mar 2000) |
| polar zone | The region in the vicinity of an electrode applied to the body. See: electrotonus. (05 Mar 2000) |
| electro-polar | <physics> Possessing electrical polarity; positively electrified at one end, or on one surface, and negatively at the other; said of a conductor. Source: Websters Dictionary (01 Mar 1998) |
| zinco-polar | <physics> Electrically polarized like the surface of the zinc presented to the acid in a battery, which has zincous affinity. Source: Websters Dictionary (01 Mar 1998) |
| law of polar excitation | A given segment of a nerve is irritated by the development of catelectrotonus and the disappearance of anelectrotonus, but the reverse does not hold; i.e., excitation occurs at the cathode when the circuit is closed and at the anode when it is opened. Synonym: Pfluger's law. (05 Mar 2000) |
| ABO blood group | <haematology> The major human blood type system which describes the oligosaccharide glycoprotein antigens found on the surface of human blood cells. According to the type of antigen present, a person may be assigned a blood type of A, B, AB or O. A second type of antigen, the Rh factor, renders a positive or negative blood type. The ABO blood group system is important because it determines who can donate blood to or accept blood from whom. Type A or AB blood will cause an immune reaction in people with type B blood and type B and AB blood will cause a reaction in people with type A blood. Conversely, type O blood has no A or B antigens, so people with type O blood are universal donors. And since AB blood already produces both antigens, people who are type AB can accept any of the other blood types without suffering an immune reaction. (04 Jul 1999) |
| actinobacteria group | A group of gram-positive, heterogeneous bacteria. This group encompasses a range of morphologically, physiologically, and chemically different organisms and includes bacteria that form cocci, short rods, irregular rods, and mycelia that fragment. (12 Dec 1998) |
| alkyl group | <chemistry> A funtional group on an organic molecule which is derived from an alkane which has lost a hydrogen atom. (13 Nov 1997) |
| aluminum group | Aluminum, boron, gallium, indium, and thallium. (05 Mar 2000) |
| amino group | <biochemistry> An -NH2 group. Organic compounds which have this group are called amines. (09 Oct 1997) |
| anterior group of axillary lymph nodes | Lymph nodes located along the lateral thoracic vein; they receive the drainage of the pectoral region, including most of the drainage of the breast. Synonym: nodi lymphatici axillaris pectorales, anterior group of axillary lymph nodes. (05 Mar 2000) |
| apical group of axillary lymph nodes | The group of lymph node's located at the apex of the axillary fossa that receive lymphatic drainage from other groups of axillary node's and then drain in turn into the subclavian lymphatic trunk. Synonym: nodi lymphatici axillares apicales. (05 Mar 2000) |
