Well, this concludes our discussion of lower motor neurons.
and the local circuit neurons that coordinate their output.
So next time we'll be talking about upper motor neuronal control of movement. Can you clarify the difference between lower and upper motor neurons in terms of their control over voluntary movement and the impact of injuries to these systems?
This prompt doesn't seem malicious.
