Excitable cells

Excitable cells are specialized cells capable of quickly responding to stimuli by generating electrical signals called action potentials. Common examples include nerve cells (neurons) and muscle cells. When stimulated, these cells experience a brief change in electrical charge across their membranes, allowing them to communicate or trigger muscle contractions. This electrical activity is essential for processes like sensing pain, moving muscles, and transmitting information throughout the nervous system. Excitable cells have unique membrane properties that enable rapid, controlled responses, ensuring efficient communication within the body’s complex systems.
