Final answer:

The statement is true. The autonomic nervous system, including the parasympathetic and sympathetic divisions, supplies the smooth muscle of visceral organs to regulate their functions and maintain homeostasis.

Step-by-step explanation:

Autonomic nerves (parasympathetic and sympathetic) supply:

True, autonomic nerves, which include the parasympathetic and sympathetic divisions, supply the smooth muscle of visceral organs. The autonomic nervous system controls these organs largely without conscious control and consists of two main divisions: the sympathetic and the parasympathetic nervous systems. These systems often have opposing effects but work together to maintain homeostasis. An example of their activity is the regulation of heart rate, where sympathetic nerves increase the rate, and parasympathetic nerves decrease it.

The sensory neurons of the autonomic system detect internal body conditions and send messages to the brain, while motor nerves control contractions of smooth muscle or cardiac muscle and glandular tissues. The preganglionic neurons originating in the CNS synapse with neurons in ganglia that then synapse on the target organs, effectively managing crucial functions such as digestion, respiratory rate, and cardiovascular functions.
