Peripheral Neural System — Predicted 2026

AI-Predicted Question Angles for UPSC 2026

Based on trend analysis, current affairs, and recurring themes in Peripheral Neural System.

Clinical correlation of cranial nerve damage

high

NEET is increasingly incorporating application-based questions. Instead of just asking for the function of a cranial nerve, a question might describe a patient's symptoms (e.g., 'difficulty swallowing and hoarseness') and ask which cranial nerve is likely affected. This tests both knowledge of function and the ability to apply it to a clinical scenario. Focus on the most common clinical presentations for each nerve.

Neurotransmitters and receptor types in ANS

medium

While the general effects of sympathetic/parasympathetic are well-covered, questions might delve deeper into the specific neurotransmitters (ACh, NE) and the types of receptors (nicotinic, muscarinic, adrenergic alpha/beta) involved at pre- and post-ganglionic synapses and effector organs. This requires a more detailed understanding of ANS pharmacology, which is a common area for higher-difficulty questions.

Specific functions of nerves arising from plexuses

medium

Beyond just identifying the plexus, questions could ask about the specific functions of major nerves emerging from them (e.g., 'What is the primary function of the median nerve?' or 'Damage to which nerve would affect diaphragm movement?'). This requires memorizing not just the plexus but also its major branches and their respective motor/sensory innervations. The phrenic nerve (from cervical plexus) is a common target.
