Final answer:
The enteric nervous system is not under conscious control, unlike the other statements. So, the correct answer is option c.
Step-by-step explanation:
The correct statement that does NOT describe basic regulation of digestive activity is the enteric nervous system is under conscious control. The enteric nervous system, which is responsible for short reflexes in the digestive tract, works independently and does not require conscious control. It regulates activities in one area of the digestive tract, coordinating local peristaltic movements and stimulating digestive secretions.
So, the correct answer is option c.
