What are the 2 factors that determine the speed of the action potential? CORRECT ANSWER- (1) the diameter of the axon (2) whether the axon is myelinated. What does it mean that an action potential is all or none and that a synaptic potential is graded? CORRECT ANSWER- a. Action potentials only happen when the electrical charge inside the axon reaches the Threshold of -55mV, then it fires. b. Postsynaptic potentials are a graded response, meaning they can build on each other (if Excitator...

Chapter 7 1. What is action potential (AP)? - correct answer the form of electrical signals called action potentials (AP), which are rapid changes in membrane potential during which the inside of the cell becomes positively charged. (-100mV) From the negative to the positive. 1. Where does an AP originate and travel to? - correct answer Originates in the axon hillock and travels to the axon terminal. 2. Define leak channels and their locations. - correct answer • Always open (non-gated)...
