| 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) |
| nervous system | The entire integrated system of nerve tissue in the body: the brain, brainstem, spinal cord, nerves and ganglia. (16 Dec 1997) |
| nervous system abnormalities | Congenital structural abnormalities of the nervous system. (12 Dec 1998) |
| nervous system, autonomic | Part of the nervous system once thought functionally independent of the brain. The autonomic nervous system regulates key functions including the activity of the cardiac (heart) muscle, smooth muscles (e.g., of the gut), and glands. The autonomic nervous system has two divisions: (1) the sympathetic nervous system, which accelerates the heart rate, constricts blood vessels, and raises blood pressure; and (2) the parasympathetic nervous system, which slows the heart rate, increases intestinal and gland activity, and relaxes sphincter muscles. (12 Dec 1998) |
| nervous system, parasympathetic | A part of the nervous system that slows the heart rate, increases intestinal and gland activity, and relaxes sphincter muscles. The parasympathetic nervous system together with the sympathetic nervous system (that accelerates the heart rate, constricts blood vessels, and raises blood pressure) constitute the autonomic nervous system. (12 Dec 1998) |
| nervous system physiology | Functions and activities of the nervous system as a whole or with reference to the peripheral or the central nervous system. (12 Dec 1998) |
| nervous system, sympathetic | A part of the nervous system that accelerates the heart rate, constricts blood vessels, and raises blood pressure. The sympathetic nervous system together with the parasympathetic nervous system (that slows the heart rate, increases intestinal and gland activity, and relaxes sphincter muscles) constitute the autonomic nervous system. (12 Dec 1998) |
| stomatognathic system | The mouth, teeth, jaws, pharynx, and related structures as they relate to mastication, deglutition, and speech. (12 Dec 1998) |
| stomatognathic system abnormalities | Congenital structural abnormalities of the mouth and jaws, including the dentition. (12 Dec 1998) |
| neuromuscular system | The muscles of the body collectively and the nerves supplying them. (05 Mar 2000) |
| neurotransmitter system | A group of nerve cells that use the sameneurotransmitter to communicate. (22 May 1997) |
| non-specific system | <physiology> A physiological term denoting that part of the brainstem reticular formation that plays a central role in the organism's bodily and behavorial alertness. It extends as a diffusely organised neural apparatus through the central region of the brainstem into the subthalamus and the intralaminar nuclei of the thalamus; by its ascending connections it affects the function of the cerebral cortex in the sense of behavioural responsiveness; its descending (reticulospinal) connections transmit its activating influence upon bodily posture and reflex mechanisms (e.g., muscle tonus), in part by way of the gamma motor neurons. See: reticular formation. Synonym: non-specific system. (05 Mar 2000) |
| noradrenergic system | The system of nerve cells that uses noradrenaline as its neurotransmitter. (13 Nov 1997) |
