Central plexuses are the name for nerve networks with sympathetic and parasympathetic fibers that all travel to the same structur automobile plexuses.
<h3>What is the term for a sympathetic and parasympathetic network?</h3>

Both sympathetic and parasympathetic nerves innervate several target areas (eg the heart, the iris muscle, some salivary glands, the gastrointestinal tract and pelvic organs).
