REY [17]

Answer:

Muscle tissue and neural tissue

Explanation:

Excitability refers to the ability of muscle and nerve cells of the respective tissues to respond to a stimulus and generate an action potential. Both muscle cells and neurons respond to a stimulus and convert it into the action potential.

Action potential refers to the electrical signal. Propagation of action potential along the membranes of these cells results in muscle contraction and functioning of neurons.

The membrane potential of these cells changes in response to the stimulus and the changed potential is propagated to the other cells.
