| vena thyroidea media | <anatomy, vein> It passes from the thyroid gland across the common carotid artery with the inferior thyroid arteries to empty into the internal jugular vein. Synonym: vena thyroidea media. (05 Mar 2000) |

| mass media | Instruments or technological means of communication that reach large numbers of people with a common message: press, radio, television, etc. (12 Dec 1998) |
| media | <pathology> Avascular middle layer of the artery wall, composed of alternating layers of elastic fibres and smooth muscle cells. (18 Nov 1997) |
| cella media | The body of the lateral ventricle of the brain, extending from the interventricular foramen (of Monro) to the collateral trigone (i.e., junction of posterior and inferior horns). Synonym: cella media. (05 Mar 2000) |
| communications media | The means of interchanging or transmitting and receiving information. Historically the media were written: books, journals, newspapers, and other publications; in the modern age the media include, in addition, radio, television, computers, and information networks. (12 Dec 1998) |
| concha nasalis media | The middle thin, spongy, bony plate with curved margins, part of the ethmoidal labyrinth, projecting from the lateral wall of the nasal cavity and separating the superior meatus from the middle meatus, the above bony plate and its thick mucoperiosteum containing a cavernous vascular bed for heat exchange. Synonym: concha nasalis media, middle turbinated bone, turbinated body. (05 Mar 2000) |
| plica umbilicalis media | A fold of peritoneum on the anterior wall of the abdomen covering the urachus, or remains of the allantoic stalk. Synonym: plica umbilicalis mediana, middle umbilical fold, plica umbilicalis media, plica urachi, urachal fold. (05 Mar 2000) |
| contrast media | <radiology> Side-effects from high osmolality / viscosity (fluid shifts from different compartments), vasodilatation, heat, pain, osmotic diuresis, haemodynamic changes, pharmacokinetics, distribute volume into extracellular space, clearance by glomerular filtration and renal excretion, physiologic reaction, increased plasma osmolality causes fluid shift from RBCs and pulmonary tissue leading to increased plasma volume, then osmolar gradient reverses with passage of contrast bolus to pulmonary capillary endothelium leaks protein into pulmonary interstitium leading to increased pulmonary oedema, transient cardiovascular changes (magnitude increased with tonicity of medium), increased PAP, increased CO with decreased peripheral/pulmonary vascular resistance, decreased systemic arterial pressure (variable), may activate gen receptors causing side effects (12 Dec 1998) |
| culture media | Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as agar or gelatin. (12 Dec 1998) |
| culture media, conditioned | Culture media containing biologically active components obtained from previously cultured cells or tissues that have released into the media substances affecting certain cell functions (e.g., growth, lysis). (12 Dec 1998) |
| culture media, serum-free | Culture media free of serum proteins but including the minimal essential substances required for cell growth. This type of medium avoids the presence of extraneous substances that may affect cell proliferation or unwanted activation of cells. (12 Dec 1998) |
| scala media | Spiral tube in the bony canal of the cochlea, lying on its outer wall between the scala vestibuli and scala tympani. (12 Dec 1998) |
| non-ionic contrast media | <radiology> A class of radiographic contrast media which do not ionise in solution, thereby decreasing effective osmolarity and toxicity. (05 Mar 2000) |
| tunica media | <anatomy> The middle coat of blood vessel walls, composed principally of thin, cylindrical, smooth muscle cells and elastic tissue. It accounts for the bulk of the wall of most arteries. The smooth muscle cells are arranged in circular layers around the vessel, and the thickness of the coat varies with the size of the vessel. (12 Dec 1998) |
| facies articularis talaris media calcanei | Underlies the head of the talus and contributes to the talocalcaneonavicular joint. Synonym: facies articularis talaris media calcanei. (05 Mar 2000) |
