D Correct answer
Explanation

Nerve cells have elongated and branched structures. These are specialised cells that are designed to stimulate other cells in the body in order to communicate. Neurons are excitable, which means they function by using electrical stimulation. Through this electrical message, known as an action potential, neurons are able to initiate action in the cells they target.
