| radiculoganglionitis | Involvement of roots and ganglia. (05 Mar 2000) |
| radiculomeningomyelitis | Inflammation of the nerve roots, the meninges, and the spinal cord. Synonym: radiculomeningomyelitis. Origin: rhizo-+ G. Meninx, membrane, + myelon, marrow, + -itis, inflammation (05 Mar 2000) |
| radiculomyelopathy | Disease involving the spinal cord and nerve roots. Synonym: radiculomyelopathy. Origin: myelo-+ L. Radicula, root, + G. Pathos, disease (05 Mar 2000) |
| radiculoneuropathy | Disease of the spinal nerve roots and nerves. (05 Mar 2000) |
| radiculopathy | <pathology> A herniated intervertebral disk (nucleus pulposus) is one which has become displaced (prolapsed) from its normal position in between the vertebral bodies of the spine. Herniated disks often impinge on nearby nerve structures resulting in pain and neurologic symptoms. A clinical situation where the radicular nerve (nerve root) is compressed by the prolapsed disk is referred to as a radiculopathy. This problem tends to occur most commonly in the cervical and lumbar spine. Origin: Gr. Pathos = disease (27 Sep 1997) |
| radiculose | <botany> Producing numerous radicles, or rootlets. Source: Websters Dictionary (01 Mar 1998) |
| radiectomy | Synonym: root amputation. Origin: L. Radix, root, + G. Ektome, excision (05 Mar 2000) |
| radiesthesia | Therapeutic cult concerned with intangible energies surrounding the living body and based on the detection of these intrinsic radiations by dowsing, or divining, or the use of more elaborate instruments (radionics). (12 Dec 1998) |
| radiferous | Containing radium. (05 Mar 2000) |
| radii | Plural of radius. Origin: L. (05 Mar 2000) |
| radii lentis | 9 to 12 faint lines on the anterior and posterior surfaces of the lens that radiate from the poles toward the equator; they mark the lines along which the ends of lens fibres abut. Synonym: lens stars, lens sutures. (05 Mar 2000) |
| radio | 1. <physics> The transmission and reception of electric impulses or signals by means of electric waves without a connecting wire, or the use of these waves for the wireless transmission of electric impulses into which sound is converted. 2. <anatomy, prefix> A combining form indicating connection with, or relation to, a radius or ray; specifically, with the radius of the forearm; as, radio-ulnar, radiomuscular, radiocarpal. Origin: L. Radius, ray (21 Jun 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. (09 Oct 1997) |
| radio frequency heating | <radiobiology> Process for heating the plasma by transferring energy to ions or electrons using waves generated by an external oscillator at an appropriate frequency. (This is similar to how a microwave oven heats food.) There are various types: See: ECRH, ICRH, and Lower Hybrid. (09 Oct 1997) |
