Quizplus · Accepted Answer

The statement "They coordinate local activity in the digestive tract" refers to the intrinsic nerve plexuses. Option A refers to the activity of pacemaker cells, which are not part of the intrinsic nerve plexuses. Option C refers to the location of the submucosal nerve plexus, which is one of the two major nerve plexuses in the digestive tract, but not the only intrinsic one. Option D refers to the location of nuclei in the brainstem that regulate the activity of the autonomic nervous system, which includes both intrinsic and extrinsic nerves that innervate the digestive tract.
