Quizplus · Accepted Answer

The myenteric plexus is an intrinsic nerve plexus that is located within the walls of the digestive tract.

Answer: B
 The myenteric plexus is involved in local changes in the digestive tract, such as regulating the contractions of smooth muscle and controlling the flow of secretions.

Answer: D
 The myenteric plexus is part of the intrinsic nervous system of the digestive tract, but it is also influenced by extrinsic autonomic nerves from the sympathetic and parasympathetic nervous systems.

Answer: E
 While the myenteric plexus does not directly produce gastrointestinal hormones, it may be involved in regulating their secretion and effects on digestion. However, intrinsic nerve plexus is a more accurate answer in this context.

Answer: A
 While external influences such as stress can indirectly affect the functioning of the digestive tract, the myenteric plexus is not directly involved in these processes.
