Define an action potential. How are the Na+, K+, and Ca+ ions involved in an action potential? How does the myelin speed up its transmission? Define a neurotransmitter. Where are they stored and how do they relay an action potential message from one cell to the next? Define threshold. How do neurotransmitters bring target cells toward or away from threshold. What happens to the response of the target cell if threshold is not reached? What happens if threshold is reached?...

13. Describe the basic sequence of events that occurs as an action potential arrives at the neuromuscular junction and is transmitted to the muscle cell and leads to a contraction. Explain at the end how relaxation of the muscle takes place (include what happens at the neuromuscular junction and in the muscle fiber. You may use some words multiple times. Fill in the blanks with a complete word or words (no abbreviations) of each step. 1. An action potential arrives...

Describe, in detail, an action potential including which ions open and when, and at what point the action potential is generated. Include the various stages of the action potential as well (ex. refractory periods)

Describe the events that take place during an action potential. Begin at the point where an EPSP reaches threshold in the trigger zone. Include all ion channels (8), ion movements (8) and potential changes (8) that take place during the various phases of the action potential.

Label a voltage-versus-time diagram of an action potential with the ions involved in each phase, the direction of their movement across the membrane, and the terms depolarize, repolarize, and hyperpolarize.

Describe how an action potential propagates along a myelinated and an unmyelinated axon, including how the potential is spread along the membrane. How are these two processes similar and how are they different? What two benefits do myelinated axons have over unmyelinated ones? Provide one way in which a myelinated axon is similar to an electrical wire and one way in which an axon is different than a wire. Why does multiple sclerosis (MS) prevent transmission in myelinated axons (that...
