2- a) Assume the following concentrations of Na⁺ and K⁺ ions: [Na⁺]_o = 120 mM, [Na⁺]_i = 6 mM, [K⁺]_o = 2 mM, and [K⁺]_i = 150 mM. Assume further that at the peak of the action potential, p_K : p_Na is 1 : 12. Calculate V_m at the peak of the action potential.(Use Goldman-Hodgkin-Katz equation, disregard Chlorine ion)

b) Explain the molecular basis of the neuronal refractory periods. That is discuss both the absolute refractory period and the relative refractory period. (Discuss with regard to ion channels)

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?...
