| capacitance | The quantity of electric charge that may be stored upon a body per unit electric potential; expressed in farads, abfarads, or statfarads. (05 Mar 2000) |
|---|---|
| capacitance flicker | <physiology> Brief closings of an ion channel during ion channel openings, observed during patch clamp (or rapid transition of an ion channel between open and closed states such that the individual channel openings cannot be distinguished properly due to the limited bandwidth of the patch clamp amplifier.) (16 Dec 1997) |
| vascular capacitance | The relationship between the volume of blood contained within a segment of vasculature and the pressure distending the vascular walls over a wide range of pressures and volumes. The veins of the body are not only conduits for the return of blood to the right heart, but they also determine most of the vascular capacitance and contain most of the blood volume. Changes in vascular capacitance provide a quick and effective mechanism for the filling of the right heart, thereby influencing cardiac output. Vascular capacitance is somewhat analogous to vascular resistance but whereas vascular resistance relates to flow through a blood vessel, vascular capacitance relates to the volume contained in it. (12 Dec 1998) |
| membrane capacitance | The electrical capacitance of a membrane. Plasma membranes are excellent insulators and dielectrics: capacitance is the measure of the quantity of charge that must be moved across unit area of the membrane to produce unit change in membrane potential and is measured in Farads. most plasma membranes have a capacitance around 1 microfarad cmexp 2. (18 Nov 1997) |
| batson venous plexus | <radiology> Paravertebral venous plexus, can carry tumour emboli directly to brain from pelvis or abdomen (12 Dec 1998) |
| vaginal venous plexus | The plexus of veins that surrounds the vagina. Synonym: plexus venosus vaginalis. (05 Mar 2000) |
| venous | <anatomy> Of or pertaining to the veins. Origin: L. Venosus (18 Nov 1997) |
| venous angioma | <radiology> Caput medusae, wedge-shaped appearance with its base at the meninges and its apex directed toward the ventricles, prominent medullary vein drains into a markedly enlarged transcortical cerebral vein, angiogram: normal arterial phase without AV shunting (12 Dec 1998) |
| venous angle | The junction of the internal jugular and subclavian veins, toward which converge the external and the anterior jugular and the vertebral veins, the thoracic duct in the left angle and the right lymphatic duct in the right angle. Synonym: Pirogoff's angle. In neuroradiology, the angle of union of the superior thalamostriate vein (vena terminalis) with the internal cerebral vein, usually closely behind the interventricular foramen of Monro. (05 Mar 2000) |
| venous artery | Origin, right ventricle of heart; distribution, it divides into the right pulmonary artery and the left pulmonary artery, which enter the corresponding lungs and branch along with the segmental bronchi. Synonym: truncus pulmonalis, arteria pulmonalis, pulmonary artery, venous artery. (05 Mar 2000) |
| venous blood | Blood which has passed through the capillaries of various tissues, except the lungs, and is found in the veins, the right chambers of the heart, and the pulmonary arteries; it is usually dark red as a result of a lower content of oxygen. (05 Mar 2000) |
| venous capillary | A capillary opening into a venule. (05 Mar 2000) |
| venous circle of mammary gland | areolar venous plexus |
| venous congestion | <physiology> Overfilling and distention of the veins with blood as a result of mechanical obstruction or right ventricular failure. (05 Mar 2000) |
| venous cutdown | <procedure> Creation of a small incised opening in a vein to permit the passage of a needle or cannula for withdrawal of blood, administration of medication, or in diagnostic or therapeutic catheterization. (12 Dec 1998) |
