| chemical shift | Dependence of the resonance frequency of a nucleus on the chemical binding of the atom or molecule in which it is contained. See: chemical shift artifact. (05 Mar 2000) |
| chemical shift artifact | In magnetic resonance imaging, a dark band caused by a biochemical difference in resonant frequency of adjacent regions rather than a true anatomic separation. (05 Mar 2000) |
| chemical solution | See: solution. (05 Mar 2000) |
| chemical sympathectomy | Destruction of the periareterial sympathetic nerves, as in Doppler's operation, by a corrosive such as phenol. (05 Mar 2000) |
| chemical synapse | <physiology> A nerve nerve or nerve muscle junction where the signal is transmitted by release from one membrane of a chemical transmitter that binds to a receptor in the second membrane. Importantly, signals only pass in one direction. (18 Nov 1997) |
| chemical synergism | Interaction of chemicals in a mixture to produce a greater toxic effect than would be expected from the sum of the toxicities of the individual chemicals. (09 Oct 1997) |
| chemical taxonomy | An approach to the classification of organisms based on the distribution of natural products. (05 Mar 2000) |
