How does a neuron maintain homeostasis?

A neuron maintains homeostasis primarily through the regulation of ion concentrations across its membrane, particularly sodium (Na+), potassium (K+), and calcium (Ca2+) ions. The sodium-potassium pump actively transports Na+ out of the cell and K+ into the cell, helping to maintain the resting membrane potential. Additionally, ion channels open and close in response to changes in membrane potential, allowing for the controlled flow of ions that supports signaling and overall cellular balance. This dynamic process ensures that neurons can respond effectively to stimuli while keeping their internal environment stable.
