| autonomic agents | Agents affecting the function of, or mimicking the actions of, the autonomic nervous system and thereby having an effect on such processes as respiration, circulation, digestion, body temperature regulation, certain endocrine gland secretions, etc. (12 Dec 1998) |
|---|---|
| autonomic denervation | The removal or interruption of some part of the autonomic nervous system for therapeutic or research purposes. (12 Dec 1998) |
| autonomic disorder | Disorganization of autonomic processes. (05 Mar 2000) |
| autonomic epilepsy | Episodes of autonomic dysfunction presumably due to diencephalic irritation. Synonym: diencephalic epilepsy, vasomotor epilepsy, vasovagal epilepsy. (05 Mar 2000) |
| autonomic fibres, postganglionic | Nerve fibres which project from cell bodies of autonomic ganglia to synapses on target organs. (12 Dec 1998) |
| autonomic fibres, preganglionic | Nerve fibres which project from the central nervous system to autonomic ganglia. In the sympathetic division most preganglionic fibres originate with neurons in the intermediolateral column of the spinal cord, exit via ventral roots from upper thoracic through lower lumbar segments, and project to the paravertebral ganglia; there they either terminate in synapses or continue through the splanchnic nerves to the prevertebral ganglia. In the parasympathetic division the fibres originate in neurons of the brainstem and sacral spinal cord. In both divisions the principal transmitter is acetylcholine but peptide cotransmitters may also be released. (12 Dec 1998) |
| autonomic ganglia | Visceral ganglia. See: autonomic nervous system. (05 Mar 2000) |
| autonomic hyperreflexia | <physiology> An autonomic response that may include hypertension, sweating, bradycardia and severe headache. Autonomic hyperreflexia may occur secondary to an injury to the upper spinal cord, during cystoscopy or with distention of the bladder or colon. (02 Jan 1998) |
| autonomic imbalance | A lack of balance between sympathetic and parasympathetic nervous systems, especially in relation to the vasomotor disturbances. Synonym: vasomotor imbalance. (05 Mar 2000) |
| autonomic motor neuron | See: motor neuron. (05 Mar 2000) |
| autonomic motor neurons | (preganglionic neuron's), by contrast, innervate smooth muscle fibres or glands only by the intermediary of a second, peripheral, neuron (postganglionic or ganglionic m. Neuron) located in an autonomic ganglion. See: motor endplate, autonomic nervous system. Synonym: anterior horn cell, motoneuron. (05 Mar 2000) |
| autonomic nerve | <anatomy, nerve> A bundle of nerve fibres outside of the central nervous system belonging or relating to the autonomic nervous system. (05 Mar 2000) |
| autonomic nerve block | Interruption of sympathetic pathways, by local injection of an anaesthetic agent, at any of four levels: peripheral nerve block, sympathetic ganglion block, extradural block, and subarachnoid block. (12 Dec 1998) |
| autonomic nervous system | <anatomy> Neurons that are not under conscious control, comprising two antagonistic components, the sympathetic and parasympathetic nervous systems. 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 that accelerates the heart rate, constricts blood vessels, and raises blood pressure. 2. The parasympathetic nervous system slows the heart rate, increases intestinal and gland activity, and relaxes sphincter muscles. (03 Jul 1999) |
| autonomic nervous system diseases | Diseases that have their major effects on the autonomic nervous system. The autonomic nervous system may be seriously affected in many other disorders including other peripheral nervous system diseases, infectious diseases (e.g., tetanus, diphtheria), immunologic diseases (e.g., acquired immunodeficiency syndrome), and systemic disorders (e.g., diabetic neuropathy, amyloid neuropathy, thyroid diseases). Disorders of central autonomic control also contribute substantially to a wide variety of problems (e.g., eating disorders, panic disorder, water-electrolyte imbalance, cardiovascular diseases).
