| FEF50/FIF50 | ratio of expiratory flow to inspiratory flow at 50% of forced vital capacity |
| FIF50 | forced inspiratory flow at 50% of forced vital capacity |
| FIVC | forced inspiratory vital capacity |
| vital ultraviolet | Rays necessary or helpful to normal growth; they promote calcium metabolism, are antirachitic in action, and have wavelengths between 3200 and 2900 A |

| noeud vital | A circumscript region in the lower part of the medulla oblongata, near the apex of the calamus scriptorius, interpreted by M. Flourens (1858) as a nerve centre controlling respiration. Synonym: vital knot, vital node. Origin: Fr. (05 Mar 2000) |
| electro-vital | Derived from, or dependent upon, vital processes; said of certain electric currents supposed by some physiologists to circulate in the nerves of animals. Source: Websters Dictionary (01 Mar 1998) |
| forced vital capacity | Vital capacity measured with the subject exhaling as rapidly as possible; data relating volume, expiratory flow, and time form the basis for other pulmonary function tests, e.g., flow-volume curve, forced expiratory volume, forced expiratory time, forced expiratory flow.

| accouchement force | Forced, artificially hastened delivery, by means of forceps, version, etc.; originally applied to rapid dilation of the cervix with the hands, with version and forcible extraction of the foetus. (05 Mar 2000) |
| anterior component of force | A force operating to move teeth anteriorly. (05 Mar 2000) |
| Begg light wire differential force technique | An orthodontic appliance utilizing small gauge labial wires with expansion and contraction loops formed into it and attached to bands fitted to individual teeth; sometimes called Begg light wire differential force technique. (05 Mar 2000) |
| bite force | The force applied by the masticatory muscles in dental occlusion. (12 Dec 1998) |
| brisement force | Forcible manipulation, usually under anaesthesia, in which the position of a deformed limb is corrected by tearing the soft tissue and crushing the bone, as in a once popular but no longer used correction for club foot deformities. Origin: Fr. Forcible breaking (05 Mar 2000) |
| radial ponderomotive force stabilisation | <radiobiology> In magnetic mirror devices, use of rf waves in the neighborhood of the ion cyclotron frequency to stabilise interchange modes. The radial ponderomotive force produced by a radial gradient in the applied rf electric field opposes the destabilising centrifugal force resulting from bad magnetic field curvature. The net particle current is in the direction that would result from field lines with good curvature, eliminating the drive for the interchange instability. (09 Oct 1997) |
| G force | Inertial force produced by accelerations or gravity, expressed in gravitational units; one G is equal to the pull of gravity at the earth's surface at sea level and 45 |
| masticatory force | The motive force created by the dynamic action of the muscles during the physiologic act of mastication. Synonym: biting strength, masticatory force. (05 Mar 2000) |
| redressement force | Straightening by force of a deformed part, as of knock-knee. Origin: Fr. (05 Mar 2000) |
| centering force | <physics, radiobiology> Term for the mutual attraction between the parallel currents in the inboard leg of the toroidal field coils in a toroidal magnetic fusion system. The portion of the coil running through the doughnut hole is attracted towards the centre of the hole. (13 Nov 1997) |
| reserve force | The energy residing in the organism or any of its parts above that required for its normal functioning. (05 Mar 2000) |
