Choose the incorrect statement regarding nerve supply in the alimentary canal
The extrinsic innervation is supplied by the autonomic nervous system
The intrinsic innervation supplied to the alimentary canal by the enteric nervous system
The sympathetic activation decreases the GI secretion and motility
The parasympathetic activation (the rest-and-digest response) suppresses neurons of the enteric nervous system and increases GI secretion
The sympathetic activation (the fight-or-flight response) restricts the activity of enteric neurons, thereby decreasing GI secretion and motility. The parasympathetic activation (the rest-and-digest response) increases GI secretion and motility by stimulating neurons of the enteric nervous system. Hence, the correct answer is option d.
