21. They are innervated by gamma motor neurons and beta motor neurons. 22. Hawking, 53, suffers from motor neuron disease, which attacks the body's nervous system. 23. The loss of motor neurons causes muscles to waste away, leading to paralysis. 24. Rilutek is a glutamate inhibitor that protects motor neurons from degenerating. 25. In the mature synapse each muscle fiber is innervated by one motor neuron . 26. Rat oculomotor nucleus motor neurons were intracellularly labelled and tested using electrophysical properties. 27. Amyotropic lateral sclerosis likewise is associated with the selective loss of motor neurons . 28. And it has powerful effects on the motor neurons that atrophy in ALS. 29. The pyramidal cells of the precentral gyrus are also called upper motor neurons . 30. Mauthner cells are thus the quickest motor neuron to respond to the stimulus.
