The resting membrane potential of a neuronal axon is -70 mV. When an action potential is triggered, Na+ ions move into the axon, which reverses the voltage, bringing it towards 0 mV. Which of the following is the correct term for this sequence of events? a. Repolarization b. Hyperpolarization c. Depolarization d. Hypopolarization e. Isopolarization

What is a resting potential? Is it positive or negative? The resting potential is mainly due to the main _____-charged large molecules stuck inside the neuron. The Na+/K+ pump pushes Na+ _____ of the cell and K+ ____ of the cell (in or out for each ion) Where is K+ concentrated, inside or outside of the neuron? Where is Na+ concentrated, inside or outside of the neuron? The action potential starts with an rise in membrane voltage. This is due...
what is the function of ATP in maintaining the resting membrane potential and during the conduction of the action potential?
Compare and contrast the molecular events of the action potential in the pacemaker cells of the SA node to those in a ventricular (contractile) cardiomyocyte. Be sure to point out how these molecular events underlie the differences in the shapes of the two types of potentials and how these differences serve the difference in functions for these cell types.
A neuron has a resting membrane potential of -70 mV; it’s trigger threshold for firing an action potential is -50 mV. Two competing signals arrive simultaneously in the trigger zone: one is a depolarizing stimulus of +40 mV, the other a hyperpolarizing stimulus of -25 mV. Will the neuron fire an action potential after integrating these signals? Why?
Compare and contrast the different cultural aspects of death. Analyze how these cultural tasks affect your nursing care.
Compare and contrast graded potentials and action potentials, with particular attention to their locations in the neuron and the ions and ion channels involved in each. 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 the physiological process involved in the conduction (propagation) 2 of an actic potential, including the types and locations of the ion channels involved....

All mammalian cells maintain the resting membrane potential across the plasma membrane. Neurons and muscle cells are capable of generating the action potential to communicate with each other. Below is a diagram showing a temporal change of the membrane potential in axon. Explain how such membrane potential is generated and/or maintained in each stage (1-3). Make sure to identify key membrane proteins and the movement of ion(s) through these membrane proteins in each stage. Calculate the membrane potential at the...
