| somatic motor neuron | See: motor neuron. (05 Mar 2000) |
|---|---|
| somatic motor nuclei | Collective term indicating the motor nuclei innervating the tongue musculature (hypoglossal nucleus) and the extraocular eye muscles (abducens nucleu, trochlear nucleus, and oculomotor nucleus). (05 Mar 2000) |
| special visceral motor nuclei | Collective term for those motoneuronal nuclei of the brainstem (n. Ambiguus, facial motor nucleus, motor nucleus of the trigeminus) that develop from the branchiomotor column of the embryo and innervate striated muscle fibres (muscles of mastication, facial musculature, pharynx and vocal cord muscles) developed from the mesenchyme of the branchial arches. Synonym: special visceral efferent nuclei, special visceral motor nuclei. (05 Mar 2000) |
| neuropathies, hereditary motor and sensory | A group of slowly progressive inherited disorders in which the predominant involvement is the peripheral motor neurons with lesser involvement of the peripheral sensory neurons. Neuronal degeneration and atrophy are characteristic of these disorders. Some of the associated characteristics are phytanic acid excess, optic atrophy, and retinitis pigmentosa. (12 Dec 1998) |
| supplementary motor area epilepsy | A localization-related epilepsy syndrome in which seizures originate from the supplementary motor area of the mesial frontal lobe. Typical seizure semiology includes sudden bilateral tonic movements, vocalization, and preservation of consciousness. Attacks are often nocturnal. (05 Mar 2000) |
| supplementary motor cortex | A region from which, by electrical stimulation, the musculature of all bodily parts can be activated, as it also can by stimulation of the motor cortex of the precentral gyrus; the region corresponds approximately to the expansion of Brodmann's area 6 over the medial surface of the cerebral hemisphere; this area has largely a bilateral representation and is concerned primarily with tonic and postural motor activities. (05 Mar 2000) |
| dorsal motor nucleus of vagus | The visceral motor nucleus located in the vagal trigone (ala cinerea) of the floor of the fourth ventricle. It gives rise to the parasympathetic fibres of the vagus nerve innervating the heart muscle and the smooth musculature and glands of the respiratory and intestinal tracts. Synonym: nucleus dorsalis nervi vagi, dorsal motor nucleus of vagus, dorsal nucleus of vagus, dorsal vagal nucleus, nucleus alae cinereae. (05 Mar 2000) |
| incito-motor | <physiology> Inciting to motion; applied to that action which, in the case of muscular motion, commences in the nerve centers, and excites the muscles to contraction. Opposed to excito-motor. Origin: L. Incitus incited + E. Motor. Source: Websters Dictionary (01 Mar 1998) |
| inhibitory-motor | <physiology> A term applied to certain nerve centers which govern or restrain subsidiary centers, from which motor impressions issue. Source: Websters Dictionary (01 Mar 1998) |
| ocular motor | Relating to or causing movements of the eyeball. (05 Mar 2000) |
| ocular motor apraxia | A congenital inability to initiate horizontal saccades. Children with this condition often use head thrusts to move their eyes to the left and right. (05 Mar 2000) |
| off-road motor vehicles | Motorised, recreational vehicles used on non-public roads. They include all-terrain vehicles, dirt-bikes, minibikes, motorbikes, trailbikes, and snowmobiles. Excludes motorcycles, which are considered public road vehicles. (12 Dec 1998) |
| evoked potentials, motor | The electrical response evoked in a muscle or motor nerve by electrical or magnetic stimulation. Common methods of stimulation are by transcranial electrical and transcranial magnetic stimulation. It is often used for monitoring during neurosurgery. (12 Dec 1998) |
| extrapyramidal motor system | Literally: all of the brain structures affecting bodily (somatic) movement, excluding the motor neurons, the motor cortex, and the pyramidal (corticobulbar and corticospinal) tract. Despite its very wide literal connotation, the term is commonly used to denote in particular the striate body (basal ganglia), its associated structures (substantia nigra; subthalamic nucleus), and its descending connections with the midbrain. (05 Mar 2000) |
| extrapyramidal motor system disease | A general term for a number of disorders caused by abnormalities of the basal ganglia or certain brain stem or thalamic nuclei; characterised by motor deficits, loss of postural reflexes, bradykinesia, tremor, rigidity, and various involuntary movements. Synonym: extrapyramidal motor system disease. (05 Mar 2000) |
