Question

Quizplus · Accepted Answer

In visceral smooth muscle, the cells are arranged in sheets rather than long fibers and are not connected by synapses. When one muscle cell contracts, the contraction spreads as a wave through the whole tissue, allowing for coordinated contractions. Contraction can be stimulated by neurotransmitters, hormones, or other chemical signals, but not exclusively by neurotransmitters. Therefore option C is the correct answer.
