Lab 4 - Smooth Muscle Motility Flashcards | Quizlet The signal, an impulse called an action potential, travels through a type of nerve cell called a motor neuron. They are similar in structure to the skeletal muscles, so doctors sometimes classify them as striated muscles. Single-unit smooth muscle cells also contain desmosomes which prevent muscle tissues from separating upon contraction.
