Nukeyfox Posted September 23, 2016 Share Posted September 23, 2016 Studying the nervous system and I was wondering why are motor neurones, sensory neurones and relay neurones all different? In what way are multipolar neurones, as in motor neurones, more effective at sending signals to muscles than unipolar neurones, as in sensory neurones? And why the cell bodies of motor neurones larger than that of sensory neurones Why don't relay neurones have myelin sheaths? My questions can be summed up as: how are the neurones adapted for their function? Link to comment Share on other sites More sharing options...
