| united states national aeronautics and space administration | An independent federal agency established in 1958. It conducts research for the solution of problems of flight within and outside the earth's atmosphere and develops, constructs, tests, and operates aeronautical and space vehicles. (12 Dec 1998) |
| los alamos national laboratory | <radiobiology> Major DOE research facility, located in Los Alamos, new Mexico, about an hour west of Santa Fe. Former home of a frozen-deuterium-fibre Z-pinch device, which was dismantled. Home to an active theory division, including the Numerical Tokamak Grand Challenge (being performed on the CM-5 massively-parallel supercomputer). Also home to former alternative-concepts experimental devices like Scyllac, FRX-A, FRX-B, FRX-C/LSM, ZT40, and the aborted CPRF which was killed in 1991 when it was almost complete (budget cuts). Currently there are some small in-house experiments, including one on electrostatic confinement as a possible fusion device, and/or a compact neutron source. They also do theory and experimental collaboration with other labs worldwide. (09 Oct 1997) |
| acromial arterial network | A vascular network between the acromion and the skin of the shoulder, formed by anastomoses of the acromial branch of the suprascapular artery with the acromial branch of the thoracoacromial artery. Synonym: rete acromiale, acromial plexus. (05 Mar 2000) |
| arteriolar network | A vascular network formed by anastomoses between minute arteries just before they become capillaries. Synonym: rete arteriosum. (05 Mar 2000) |
| articular network | A vascular rete in the neighborhood of a joint, where such arrangements are common, enabling a collateral circulation by which blood will be supplied distal to the joint regardless of compromises resulting from joint position. Synonym: circulus articularis vasculosus, rete vasculosum articulare, articular network. (05 Mar 2000) |

Synonym: circulus articularis vasculosus, rete vasculosum articulare, articular network. (05 Mar 2000) |
| articular vascular network of elbow | Vascular networks in the region of the elbow, composed of anastomoses between branches of the radial and middle collateral, superior and inferior ulnar collateral, radial recurrent, interosseous recurrent, and recurrent ulnar arteries. Synonym: rete articulare cubiti. (05 Mar 2000) |
| articular vascular network of knee | An arterial network over the front and sides of the knee, formed by branches of the descending genicular artery, of the five genicular arteries from the popliteal, of the anterior tibial recurrent, and of the fibular circumflex branch of the posterior tibial. Synonym: rete articulare genus. (05 Mar 2000) |
| calcaneal arterial network | A superficial network over the calcaneus, formed by branches of the peroneal and posterior tibial arteries and twigs from the malleolar retia. Synonym: rete calcaneum. (05 Mar 2000) |
| patellar network | The superficial portion of the articular vascular network of the knee. Synonym: rete patellae. (05 Mar 2000) |
| medial malleolar network | A network over the medial malleolus formed by branches from the anterior and posterior medial malleolar and medial tarsal arteries. Synonym: rete malleolare mediale. (05 Mar 2000) |
| peritarsal network | The lymphatic vessels along the margin of the eyelid. (05 Mar 2000) |
| chromatin network | The appearance of basophilic material in the nuclei of many cells after fixation. See: chromatin. (05 Mar 2000) |
| microtrabecular network | <cell biology> Complex network arrangement seen using the high voltage electron microscope to look at the cytoplasm of cells prepared by very rapid freezing. The suggestion was that most cytoplasmic proteins are in fact loosely associated with one another in this fibrillar network and are separate from the aqueous phase that contains only small molecules in true solution. If it exists, then it must certainly be very labile in cells where there is cytoplasmic flow and rapid organelle movement, now considered artifactual by most microscopists. (18 Nov 1997) |
