Sanshool is a natural compound found in sichuan pepper, which is commonly used in making spicy asian food, and creates a numbing sensation in the mouth. it is known to inhibit a subset of potassium leak channels involved in maintaining the resting membrane potential in sensory neurons. how do you think sanshool affects these sensory neurons?
a. it elevates the resting potential (to less negative values) and makes it easier to excite the neuron.
b. it elevates the resting potential and makes it harder to excite the neuron.
c. it lowers the resting potential and makes it easier to excite the neuron.
d. it lowers the resting potential and makes it harder to excite the neuron.
e. it causes hyperpolarization and decreases the spontaneous firing of the neuron.

Match the following terms describing electrical events with the correct phases of the cardiac cycle. the ventricular muscle cells depolarize at the start of this phase. during this phase, na+ entry through the funny channels causes the pacemaker potential of sa nodal cells to gradually become less negative until it reaches threshold. the ventricular muscle cells repolarize right before this phase. the cytosolic concentration of calcium in the contractile cells of the ventricle is highest during this phase. a. isovolumetric relaxation b. ventricular ejection c. isovolumetric contraction d. ventricular filling
