| motor system disease | <disease> Degenerative disease of unknown cause that affects predominantly motor neurons of spinal cord, cranial nerve nuclei and motor cortex. There is speculation that deficiency in ciliary neurotrophic factor may be involved. (18 Nov 1997) |
|---|---|
| motor tic | <neurology> A repetitive spasmodic movement of the eyes or facial muscles. May also involve the neck or shoulders. Tics are most common in children. The cause is unknown but may be linked to stress. Tics are more common in children with attention deficit hyperactivity disease. Most tics require no treatment and resolve on their own with patient education. (27 Sep 1997) |
| motor unit | A single somatic motor neuron and the group of muscle fibres innervated by it. (05 Mar 2000) |
| motor vehicles | Automobiles, trucks, buses, or similar engine-driven conveyances. (12 Dec 1998) |
| motor zone | That portion of the cerebral cortex, primarily the posterior region of the frontal lobe, near the central sulcus, which when stimulated produces a movement and when injured produces spasticity or paralysis. (05 Mar 2000) |
| plastic motor | An artificial point of attachment on an amputation stump to which is fastened the cord or extensor by which movement is transmitted to an artificial limb; used in cinematization. (05 Mar 2000) |
| postganglionic motor neuron | See: motor neuron. (05 Mar 2000) |

| hydraulic motor | By altering the internal osmotic pressure within a cell, water will enter and a considerable expansion of the compartment will occur. This has been used as a motor device in plants (turgor pressure), in eversion of nematocysts and possibly in the production of other cellular protrusions. (18 Nov 1997) |
| 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 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) |
