In the nervous system, the strength of the stimulus is coded into: At what membrane voltage do neuronal voltage-gated Na+ channels become activated? Repolarization and hyperpolarization are due to the activity of K+ channels. They include diverse potentials such as receptor potentials, electrotonic potentials, subthreshold membrane potential oscillations, slow-wave potential, pacemaker potentials, and synaptic potentials, which scale with the magnitude of the stimulus. There are periodic gaps in the myelin sheath on the axon of certain neurons that serves to facilitate the rapid conduction of nerve impulses. of graded potential. Which ion is pumped into the axon of a neuron to help maintain the resting potential? Graded potentials that make the membrane potential less negative or more positive, thus making the postsynaptic cell more likely to have an action potential, are called excitatory postsynaptic potentials (EPSPs). JR Krishna (author) from India on September 05, 2012: nenytridiana from Probolinggo - Jawa Timur - Indonesia on September 05, 2012: Oh! The transmitter diffuses across the synaptic cleft and activates ligand-gated ion channels that mediate the EPSP. Which of the following ions are involved in neuronal action potentials? 2.
