| motor roots of submandibular ganglion | <anatomy, nerve> Motor roots of submandibular ganglion; communicating branches between submandibular ganglion and lingual nerve. Synonym: rami communicantes ganglii submandibularis cum nervo linguali, motor roots of submandibular ganglion. (05 Mar 2000) |
|---|---|
| motor skills | Performance of complex motor acts. (12 Dec 1998) |
| motor skills disorders | Marked impairments in the development of motor coordination such that the impairment interferes with activities of daily living. (12 Dec 1998) |
| motor speech centre | The posterior part of the inferior frontal gyrus of the left or dominant hemisphere, corresponding approximately to Brodmann's area 44; Broca identified this region as an essential component of the motor mechanisms governing articulated speech. Synonym: Broca's area, Broca's field, motor speech centre. (05 Mar 2000) |
| 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) |
| preganglionic 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) |
