Nerve and muscle tissues are considered excitable because they produce electrical signals when excited. a. True b. False

True

Explanation:

The production of electrical signals or the generation of the action potential is the result of the movement of ions which causes depolarization and repolarization in the neuron cells.

The electrical signal is produced in response to the external stimulus when the receptors present in the sensory organs generate signals like in the skin, nose, eyes.

There are some autonomic responses in the body that are coordinated by the generation of the signals in the neurons and the muscles like in the autorhythmicity in the cardiac muscles.

Thus, True is the correct answer.
