What term describes the study of electricity in living tissues?

• A. Cardiology
• B. Neurology
• C. Electrophysiology
• D. Electromagnetism

Answer: (C)

The main concept tested is how electrical signals are produced and measured in living tissues, which is described by electrophysiology. This field focuses on the electrical properties of biological cells and tissues—how resting membrane potentials are established, how action potentials are generated and propagated, and how ions flowing through channels create those signals. Techniques like patch-clamp recordings, intracellular or extracellular electrodes, EEG, and ECG are all ways electrophysiology investigates how nerves and muscles communicate through electricity. Cardiology deals with heart structure, function, and disease, not specifically the electrical study of tissues. Neurology covers the nervous system broadly, including its functions and disorders, but electrophysiology specifically targets the electrical phenomena of living tissues. Electromagnetism is the physics of electric and magnetic fields in general, not the specialized study of biological electrical signals.
