### Transcription and ExplanationThis image contains a graph illustrating the phases of action potential typically found in cardiac cells. The graph plots membrane potential (in millivolts, mV) on the vertical axis against time (in seconds) on the horizontal axis.#### Graph Details:1. **Axis:** - **Vertical Axis (Y-axis):** Represents membrane potential, ranging from -80 mV to +20 mV. - **Horizontal Axis (X-axis):** Represents time, showing intervals where different phases occur.2. **Graph Lines and Phases:** - **Line 'a':** Represents the depolarization phase, where the membrane potential rises steeply from around -60 mV to above 0 mV, peaking at about +20 mV. - **Line 'b':** Represents the repolarization phase, where the potential returns from its peak back toward the resting potential. - **Lines 'c' and 'd':** Likely representing the pacemaker potential, where the membrane potential slowly increases from around -60 mV toward the threshold for the next depolarization.#### Interactive Elements:- Below the graph, there are dropdown menus labeled: - `a [Choose]` - `b [Choose]` - `c and d [Choose]`Each dropdown allows the user to select from different options to match the phases of action potential. The options provided in the menu are:- Depolarization phase- Repolarization phase- Pacemaker potentialThis interactive feature is designed to test the user's ability to correctly identify and match the phases of action potential based on the graph.

Caffeine lowers the heart rate by increasing rates of depolarization at the SA node True False Nicotine raises the heart rate because it stimulates the activity of the sympathetic neurons in medulla oblongata True False The Frank-Starling Law of the Heart states that the force of heart contraction is directly proportional to the initial length of the muscle fiber, within optimal limits of length True False If the sarcomeres stretched beyond the optimal length, the force of contraction would go down, but that can potentially happen only during open heart surgery when the heart is not constrained by the pericardium, lungs, ribs and diaphragm. True False It is the Na+ channel-driven spontaneous depolarization that is affected by sympathetic and parasympathetic inputs to speed up or slow down the firing rate of the SA node and other conductive cells. True False

Subject: Neurophysiology The neuron for this experiment is in a bath with [K+] = 2 mM and [Na+] = 150 mM. Calculate the Nernst Equilibrium potential for each ion. What is your estimate for the gNa and for gK? If you are more comfortable, use PNa and PK. Remember, these values should be between 0 and 1. What is the resting membrane potential for this cell? Draw an action potential for this neuron in this solution. Keep in mind that this neuron is in unusual solutions. Label each axis and indicate inward and outward currents. Be absolutely certain to label the peak voltage and threshold for the AP!
