1How are electrical signals generated and moved within neurons23

Notes

**How are electrical signals generated and moved within neurons?** Mainly, electrical signals within neurons are generated through the process of creating and maintaining a resting potential, which involves the pumping of sodium and potassium ions to establish concentration gradients across the neuron's plasma membrane. This process is driven by energy from ATP, which powers the active transport of these ions in opposite directions. The resulting difference in ion distribution causes the membrane to become polarized, leading to a negative resting potential. When a neuron is stimulated, it can generate an action potential, which is a rapid, temporary change in the membrane potential. This electrical impulse propagates along the nerve fibers, such as the axon, by a process involving the movement of positively charged ions like sodium and potassium across the membrane. The impulse travels as a wave of depolarization and repolarization, moving along the length of the neuron. **How can neurons interact with other cells?** Neurons communicate with each other and with effector cells primarily through synapses, which are junctions between neurons or between neurons and effector cells. ...
