    Dear Student,

    This is a very detailed topic but I will try to give you a concise outline that you can elaborate yourself. Motor neurons are efferent neurons that originate in spinal cord and form synapse with muscle fibers. They have an electrical gradient across their cell membranes, with the inside of the cell being negative with respect to the outside at rest. This is known as the resting potential and is usually -70 to -90mV. ...
