| motor | <neurology, physiology> A muscle, nerve or centre that effects or produces movement. (18 Nov 1997) |
|---|---|
| motor abreaction | The release of an unconscious thought, idea, or impulse through motor or muscular expression. (05 Mar 2000) |
| motor activity | The physical activity of an organism as a behavioural phenomenon. (12 Dec 1998) |
| motor agraphia | Agraphia due to muscular incoordination. (05 Mar 2000) |
| motor amusia | Inability to produce music. (05 Mar 2000) |
| motor aphasia | A type of aphasia in which there is a deficit in speech production or language output, often accompanied by a deficit in communicating by writing, signs, etc. The patient is aware of his impairment. Synonym: anterior aphasia, ataxic aphasia, Broca's aphasia, expressive aphasia, nonfluent aphasia. (05 Mar 2000) |
| motor apraxia | An inability to make movements or to use objects for the purpose intended. Synonym: cortical apraxia, innervation apraxia, limb-kinetic apraxia. (05 Mar 2000) |
| motor area | Area of the frontal lobe concerned with primary motor control. It lies anterior to the central sulcus. (12 Dec 1998) |
| motor ataxia | Ataxia developing upon attempting to perform coordinated muscular movements. Synonym: kinetic ataxia. (05 Mar 2000) |
| motor cell | A neuron whose axon innervates peripheral effector cell's such as muscle fibres or gland cell's. (05 Mar 2000) |
| motor cortex | Area of the frontal lobe concerned with primary motor control. It lies anterior to the central sulcus. (12 Dec 1998) |
| motor dapsone neuropathy | A peripheral neuropathy due to ingestion of 4,4-deaminodiphenylsulphone. (05 Mar 2000) |
| motor decussation | The intercrossing of the bundles of the pyramidal tracts at the lower border region of the medulla oblongata. Synonym: decussatio pyramidum, decussatio motoria, motor decussation. (05 Mar 2000) |
| motor endplate | The specialised postsynaptic region of a muscle cell. The motor endplate is immediately across the synaptic cleft from the presynaptic axon terminal. Among its anatomical specializations are junctional folds which harbor a high density of cholinergic receptors. See: neuromuscular junction (12 Dec 1998) |
| motor fibres | Nerve fibre's that transmit impulses that activate effector cells, e.g., in muscle or gland tissue. (05 Mar 2000) |
