Chapter 11, Problem 14CYR

Mark the following statements as true or false. If a statement is false, correct it to make a true statement.

a. The resting membrane potential refers to the voltage difference across the membranes of excitable cells at rest.

b. The concentration of Na + is highest in the cytosol, and the concentration of K + is highest in the extracellular fluid.

c. The Na + / K + pumps and gated channels maintain the Na + and K + gradients necessary for action potentials to occur.

d. A depolarization is a change in membrane potential that makes the potential less negative.

e. A local potential is a change in membrane potential that conducts the long-distance signals of the nervous system.

An 82-year-old woman is brought to the emergency room complain- ing of nausea, vomiting, muscle cramps, and generalized weakness. Labo- ratory analysis reveals significant hyperkalemia. Elevations of extracellular potassium ion concentration will have which of the following effects on nerve membranes? a. The membrane potential will become more negative b. The sodium conductance will increase c. The potassium conductance will increase d. The membrane will become more excitable e. The Na*-K* pump will become inactivated
Draw and discuss an AP (action potential). Below this graph draw and discuss the conductance of the important ions moving across this membrane that makes the action potential work. a. Cardiac fiber (non automatic cells) b. SA (self excitable cells)
The figure below may help in answering some of the questions. 1. What ions are flowing (and in which direction) both during the rising phase and the falling phase of the action potential? 2. What are the values of both the 'y' (vertical) axis and the 'x' (horizontal) axis. 3. If extracellular levels of K+ rose (a condition called hyperkalemia), how would that affect the resting membrane potential? 3
