Final answer:
The stomach receives parasympathetic activation via the vagus nerve, which increases GI secretion and motility.
Step-by-step explanation:
The stomach receives parasympathetic activation via the vagus nerve. The parasympathetic activation stimulates neurons of the enteric nervous system, which increases GI secretion and motility. In contrast, sympathetic activation restricts the activity of enteric neurons, leading to decreased GI secretion and motility.
