| hypoxia warning system | A device designed to produce an audio or visual signal at a predetermined level of oxygen partial pressure; ideally, the system would warn of impending hypoxia in time for corrective action to be taken. (05 Mar 2000) |
| solar system | The group of celestial bodies, including the earth, orbiting around and gravitationally bound by the sun. It includes nine planets, 34 natural satellites, more than 1,000 observed comets, and thousands of lesser bodies known as minor planets (asteroids) and meteoroids. (12 Dec 1998) |
| somesthetic system | Sensory data derived from skin, muscles, and body organs in contrast to that derived from the five special senses. (05 Mar 2000) |
| SOS system | The DNA repair system also called error prone repair in which apurinic DNA molecules are repaired by incorporation of a base that may be the wrong base but that permits replication. RecA protein is required for this type of repair. SOS genes function in control of the cell cycle in pro and eu karyotes. (18 Nov 1997) |
| static system | That part of the neuromuscular system whereby the animal organism is maintained in posture and equilibrium, and counteracts the forces of gravity and atmospheric pressure; distinguished from the kinetic system. (05 Mar 2000) |
