Question

all muscle types will respond to an electrical stimulus because all muscle coareexcitablecontractilestriatedinvoluntaryisometric

Explanation:

Muscle cells have the property of excitability, which means they can respond to electrical stimuli. Contractile refers to the ability to shorten (contract), but the key here is the response to electrical stimulus. Striated refers to a type of muscle appearance (like skeletal and cardiac), not all muscles are striated (smooth muscle isn't). Involuntary refers to muscle control (not consciously controlled, like smooth and cardiac), but it's not about response to electrical stimulus. Isometric is a type of muscle contraction (length doesn't change), not relevant to responding to electrical stimulus.

Answer:

excitabile
