electroplax
A stack of specialized muscle fibres found in electric eels, arranged in series. The fibres have lost the ability to contract; instead they generate extremely high voltages (ca 500 V) in response to nervous stimulation. They contain asymmetrically distributed sodium-potassium ATPases, acetylcholine receptors and sodium gates at extraordinarily high concentrations.
