| 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). (12 Dec 1998) |
| autonomic neurogenic bladder | Malfunctioning bladder, secondary to low spinal cord lesions. (05 Mar 2000) |
| autonomic neuropathy | <neurology, pathology> A group of symptoms which is caused by damage to the nerves which supply the internal organs. May be associated with diabetes, alcohol abuse, trauma (nerve injury) and the use of anticholinergic medications. Symptoms include abdominal swelling, heat intolerance, nausea, vomiting, impotence, diarrhoea, constipation, dizziness with standing, difficulty urinating and urinary incontinence. Origin: Gr. Pathos = disease (27 Sep 1997) |
| autonomic nuclei | Nuclei located in the spinal cord (T1-L2, S2-S4) and in the brainstem (Edinger-Westphal nucleus, superior and inferior salivatory nuclei, dorsal vagal nucleus and parts of the ambiguus nucleus) from which general visceral efferent preganglionic fibres arise; may be sympathetic (T1-L2) or parasympathetic (craniosacral); hypothalamic nuclei/areas function in concert with autonomic nuclei. (05 Mar 2000) |
| autonomic part | <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) |
| autophagocytosis |
Autophagy, or autophagocytosis, is a process of organelle degradation that takes place inside the cell. It is executed by lysosomes and is part of everyday normal cell growth and development. Its main purpose is to maintain a balance between biogenesis (production) of cell structures, and their degradation and turnover (see Bruce Alberts et al.: Molecular biology of the cell, 4th edition, Garland Publishing 2002, NCBI Bookshelf). ...

| autophobia |
The English suffix -phobia is technically used to describe irrational, disabling fear as a mental disorder, and commonly misused to describe hatred of a particular thing or subject. Everyday language has misused the use of this suffix as a mild or irrational fear with no serious substance; however, its origin is from areas of psychiatry which study serious phobias which disable a person's life. ...

| autism |
Autism is considered a neurodevelopmental disorder that manifests itself in marked problems with social relatedness, communication, interest, and behavior. The field of psychiatry has classified it in the DSM as one of the five types of pervasive developmental disorders (or autism spectrum disorders). The etiology and physiological basis for autism are unknown, and the psychiatric criteria for the diagnosis are based on behavioral attributes rather than clinical tests. ...

| autosuggestion |
Autosuggestion is a process by which an individual trains the subconscious mind to believe something, or systematically schematizes the person's own mental associations, usually for a given purpose. This is accomplished through self-hypnosis methods or repetitive, constant self-affirmations, and may be seen as a form of self-induced brainwashing. The acceptance of autosuggestion may be quickened through mental visualization of that which the individual would like to believe. ...
