Andrew was taken to the doctor’s office after he was bitten by a stray dog. The concern was that the dog might be infected with the rabies virus. The rabies virus infects neurons by using which method that normally transports materials from the synaptic knob to the cell body? a. anterograde transport b. fast axonal transport c. slow axonal transport d. All of these are correct.
Does skeletal muscle, like cardiac muscle, have gap junctions between adjacent cells? Why or why not?
