| residual schizophrenia | Blunted or inappropriate affect, social withdrawal, eccentric behaviour, or loose associations, but without prominent psychotic symptoms, as the remains of former psychotic symptoms of schizophrenia. (05 Mar 2000) |
|---|---|
| residual urine | Urine remaining in the bladder at the end of micturition in cases of prostatic obstruction, bladder atony, etc. (05 Mar 2000) |
| residual volume | The volume of air remaining in the lungs at the end of a maximal expiration. Common abbreviation is rv. (12 Dec 1998) |
| neoplasm, residual | Remnant of a tumour or cancer after primary, potentially curative therapy. (dr. Daniel masys, written communication) (12 Dec 1998) |
| functional residual air | The volume of air remaining in the lungs at the end of a normal, quiet expiration. It is the sum of the residual volume and the expiratory reserve volume. Common abbreviation is frc. (12 Dec 1998) |
| functional residual capacity | The volume of air remaining in the lungs at the end of a normal, quiet expiration. It is the sum of the residual volume and the expiratory reserve volume. Common abbreviation is frc. (12 Dec 1998) |
| action current | An electrical current induced in muscle fibres when they are effectively stimulated; normally it is followed by contraction. (05 Mar 2000) |
| alternating current | Electrical current which alternates direction periodically. (For instance, household electric current is AC alternating at 60 oscillations/sec (60 Hertz) in the United States, and 50 Hertz in many other countries.) Acronym: AC (09 Oct 1997) |
| anodal current | A current produced in tissues under the anode when the circuit is closed. (05 Mar 2000) |
| ascending current | The direction of current flow in a nerve when the anode is placed peripheral to the cathode, in contrast to descending current; the convention used is that current flows from positive to negative. Synonym: centripetal current. (05 Mar 2000) |
| axial current | The central rapidly moving portion of the bloodstream in an artery. (05 Mar 2000) |
| bootstrap current | <radiobiology> Currents driven in toroidal devices by neo-classical diffusion. They may amount to a substantial fraction of the net current in a tokamak reactor, thus lengthening the pulse time or decreasing the power needed for current drive. (09 Oct 1997) |
| calcium current | Inflow of calcium ions through specific calcium channels. Critically important in release of transmitter substance from presynaptic terminals. (18 Nov 1997) |
| galvanic current | See: direct current, galvanism. (05 Mar 2000) |
| radio frequency current drive | <radiobiology> Plasma waves in the radio-frequency range can be used to push plasma particles in such a way that current forms in the plasma, this is a method of non-inductive current drive which would allow for steady-state fusion reactors to operate.
