                    1. TTX and TEA are abbreviation of __________and__________ ? 
                  
                  
                  
                
                  
                    2. Voltage clamp technique is used to study: 
                  
                  
                  
                
                  
                    3. Voltage clamp measures _______ 
                  
                  
                  
                
                  
                    4. Main two components of ionic current are: 
                  
                  
                  
                
                  
                    5. Voltage clamp is used by electrophysiologists to measure the ________ currents across a neuronal membrane while holding the membrane voltage at a step level:
