Question

Quizplus · Accepted Answer

The sympathetic and parasympathetic fibers that innervate the heart pass through the cardiac plexus, which is a network of nerves located near the base of the heart. This plexus is responsible for regulating the heart rate and controlling the strength of the heart's contractions. The celiac and hypogastric plexuses are involved in the innervation of other organs, such as the gastrointestinal tract and pelvic organs. The sphenopalatine and otic ganglia are part of the autonomic nervous system, but they are not involved in the innervation of the heart.
