Answer to Question 1

B
Feedback:
The gastroenteric reflex is stimulation of the stomach, which causes an increase in activity in the small intestine. The duodenalcolic reflex stimulates colon activity and mass movement. The gastrocolic reflex is stimulation in the stomach, which increases activity in the colon. The ileogastric reflex is the introduction of chyme or stretch to the large intestine and slow stomach activity.

Answer to Question 2

A
Feedback:
Sumatriptan binds to serotonin receptors to cause vasoconstrictive effects on cranial blood vessels. The other options are incorrect.
