The answer should be NEURONES (nerve cells).
Neurons transmit electrical signals called NERVE IMPULSES from the cell body through the axon to the end plate. The junction between the end plate and the adjacent cell is called SYNAPSE. impulses passes through the synapse by diffusion of chemicals.
        
             
        
        
        
Lipophilic hormones,

would affect their diffusion.  The carrier proteins are mainly the serum
albumins.
