Afterward, to restore the neuron's resting potential, the ion channels close and ion pumps embedded in the membrane pump the sodium ions back out of the cell, while they move potassium ions back into the cell. Now, the neuron is ready for another action potential....
Values for resting and action potentials of Helisoma salivary gland cells are much the same as in most neurones and muscle cells. The resting potential is primarily due to the distribution of potassium ions across the membrane, with a sm... RD Hadley,AD Murphy,SB Kater - 《Journal of Exper...

(Ca) ions are also important in maintaining the resting membrane potential in muscle cells. The Ca2+ions are stored in an organelle called the sarcoplasmic reticulum, which contains protein pumps to maintain high concentrations of Ca2+inside the compartment. When amuscle cellis told to contract, ...
From the nervous system of Aplysia, we have cloned a new class of noninactivating K+ channels (aKv5.1) that are activated at low voltage and are capable of contributing to the resting potential and firing patterns of neurons. Expression of aKv5.1 in Aplysia neuron R15 revealed that aKv5.1...
