Regulation of Digestion — Predicted 2026
AI-Predicted Question Angles for UPSC 2026
Integrated Neural and Hormonal Control
highNEET often tests the integrated understanding of biological processes. A question might present a scenario (e.g., 'A person consumes a fatty meal') and ask about the sequence of neural and hormonal responses, or which specific hormones and nerves would be activated and their combined effects. This requires students to connect the cephalic, gastric, and intestinal phases with the actions of specific hormones and the vagal/sympathetic innervation. For example, a question could ask about the combined effect of CCK and the enterogastric reflex on gastric emptying after a fatty meal.
Clinical Correlation/Dysfunction
mediumWhile NEET primarily focuses on normal physiology, questions sometimes touch upon the consequences of regulatory dysfunction. For instance, a question might describe a condition where there is excessive gastric acid secretion and ask which hormone's overproduction could be responsible (e.g., Gastrinoma). Or, it could ask about the impact of vagotomy (cutting the vagus nerve) on gastric secretion. This tests a deeper understanding of the regulatory mechanisms and their importance in maintaining health.
Specific Neurotransmitters/Peptides in ENS
lowWhile the general roles of ENS plexuses are important, questions delving into specific neurotransmitters (e.g., VIP, Substance P, NO) within the ENS and their precise actions are less common but possible for a 'hard' level question. For example, a question might ask about a neurotransmitter that causes relaxation of GI smooth muscle or stimulates intestinal secretion, testing knowledge beyond the main hormones. This would require a more detailed recall of ENS pharmacology.
