| Amyotrophic lateral sclerosis is a progressive disease affecting both upper and lower motor neurons. |
| At early stages of development, single muscle fibers are innervated by axon terminals from several different motor neurons. |
| Proprioceptor afferents project to the phrenic motor neurons and affect their firing rate. |
| In blowflies, a subset of these sensors make strong monosynaptic connections with the motor neurons of steering muscles. |
| University of Wisconsin-Madison researchers have turned human embryonic stem cells into spinal motor neurons. |
| Effective speech depends also on the motor neurons in the cervical and thoracic parts of the spinal cord that serve the muscles of breathing. |
