Question

Quizplus · Accepted Answer

Collateral ganglia are indeed part of the sympathetic nervous system, but they are not located within the sympathetic chain ganglia. Instead, they are distinct structures where sympathetic preganglionic neurons synapse with postganglionic neurons, typically involved in innervating organs in the abdominal and pelvic regions.
