|---|---|
| intramedullary mass | <radiology> Ependymoma, astrocytoma, syrinx, post-radiation myelopathy, haematoma (posttraumatic or AVM) (12 Dec 1998) |
| the large mass of the telencephalon | On either side of the midline, consisting of the cerebral cortex and its associated fibre systems, together with the deeper-lying subcortical telencephalic nuclei (i.e., basal ganglia [nuclei]). (05 Mar 2000) |
| tubular excretory mass | The mass of functioning excretory tubules of the kidney determined from the excretion of iodopyracet, or other compounds processed in the kidney primarily by tubular secretion, when large doses are used. (05 Mar 2000) |
| extradural mass | <radiology> Disc, haematoma (traumatic fracture), metastasis (epidural, bony), abscess, neurofibroma, lipoma, arachnoid cyst (12 Dec 1998) |
| unit of mass | Metric system: gram, SI: kilogram, english system: pound. (05 Mar 2000) |
| filar mass | A filamentous plasmatic material, beaded with granules, demonstrable by means of vital staining in the immature red blood cells. Synonym: alpha substance, filar mass, filar substance, substantia reticularis, substantia reticulofilamentosa. Synonym: reticular formation. (05 Mar 2000) |
| lateral mass of atlas | The thick lateral part of the atlas on each side that articulates above with the occipital condyle and below with the axis. Synonym: massa lateralis atlantis. (05 Mar 2000) |
| lateral mass of ethmoid bone | A mass of air cells with thin bony walls forming part of the lateral wall of the nasal cavity; the cells are arranged in three groups, anterior, middle, and posterior, and are closed laterally by the orbital plate which forms part of the wall of the orbit. Synonym: labyrinthus ethmoidalis, ectethmoid, ectoethmoid, lateral mass of ethmoid bone. (05 Mar 2000) |
| fourth ventricle mass | <radiology> IN ADULTS: choroid plexus papilloma, haemangioblastoma, vermian metastasis, arteriovenous malformation (AVM), inflammatory mass/cyst IN KIDS: medulloblastoma, uniform enhancement, homogeneous, ependymoma, patchy enhancement, heterogeneous, calcified (12 Dec 1998) |
| law of mass action | <chemistry> This law states that the rate of a given chemical reaction is proportional to concentration of the reactants. (09 Oct 1997) |
| accelerator factor | <chemical> Heat- and storage-labile plasma glycoprotein which accelerates the conversion of prothrombin to thrombin in blood coagulation. Factor v accomplishes this by forming a complex with factor xa, phospholipid, and calcium (prothrombinase complex). Deficiency of factor v leads to owren's disease. Chemical name: Blood-coagulation factor V (12 Dec 1998) |
| acetate replacement factor | <biochemistry> 1,2 dithiolane 3 valeric acid. Regarded as a coenzyme in the oxoglutarate dehydrogenase complex of the citric acid cycle. Involved generally in oxidative decarboxylations of _ keto acids. A growth factor for some organisms. (18 Nov 1997) |
| adrenal weight factor | A postulated substance of adenohypophysial origin responsible for maintenance of the weight of the adrenal cortex. (05 Mar 2000) |
| adrenocorticotropic releasing factor | Hormone produced by hypothalamus that causes pituitary to secrete adrenocorticotropic hormone. (05 Mar 2000) |
