| motor neuron | Synonym for motoneuron. (18 Nov 1997) |
| motor neuron 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) |
| postganglionic motor neuron | See: motor neuron. (05 Mar 2000) |
| preganglionic motor neuron | See: motor neuron. (05 Mar 2000) |
| upper motor neuron | Clinical term indicating those neuron's of the motor cortex that contribute to the formation of the pyramidal or corticospinal and corticobulbar tracts, as distinguished from the lower motor neuron's innervating the skeletal muscles. Although not motor neuron's in the strict sense, these cortical neuron's became colloquially classified as motor neuron's because their stimulation produces movement and their destruction causes severe disorders of movement. See: motor neuron, motor cortex. (05 Mar 2000) |
| upper motor neuron lesion | Injury to cerebral descending (corticonuclear) fibres above the brainstem or spinal motor nerve nucleus. Synonym: upper motor neuron lesion. (05 Mar 2000) |
| lower motor neuron | Clinical term used to indicate the final motor neuron's that innervate the skeletal muscles; distinguished from upper motor neuron's of the motor cortex that contribute to the pyramidal or corticospinal tract. See: motor neuron. (05 Mar 2000) |
| lower motor neuron dysarthria | Dysarthria caused by dysfunction of the motor nuclei and the lower pons or medulla, or other neural connections, central and peripheral to the muscles of articulation. (05 Mar 2000) |
| lower motor neuron lesion | Injury to motor cells in the brainstem or spinal cord, or of the axons derived from them. (05 Mar 2000) |
| general somatic afferent column | In the embryo, a column of gray matter in the hindbrain and spinal cord, represented in the adult by the sensory nuclei of the trigeminal nerve and relay cells in the dorsal horn. (05 Mar 2000) |
| general somatic efferent column | A column of gray matter in the embryo, represented in the adult by the nuclei of the oculomotor, trochlear, abducens, and hypoglossal nerves and by motor neurons of the ventral horn of the spinal cord. (05 Mar 2000) |
