Definitions:

Depolarization

The reduction in the electrical charge difference across a cell's plasma membrane, leading to the initiation of an action potential.

Resting Potential

The electrical charge difference across the cell membrane while a neuron is at rest, typically around -70mV, enabling the potential for action potentials.

Action Potential

A rapid increase and subsequent decrease in voltage across a cellular membrane, allowing neurons and muscle cells to communicate and react to stimuli.

Convergence

The evolutionary process where organisms from different evolutionary backgrounds develop similar traits or features in response to similar environmental challenges or functional needs.
