NEET 2025 Biology Neural Control and Coordination Questions

Use this page to connect the official 2025 paper with current Biology practice. NeetVellum does not claim a chapter appeared in that paper until the official question and final key have been mapped.

What to master

neurons, impulse transmission, central nervous system, reflexes and sensory systems.

Original practice preview

These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.

Example 1 · difficulty 2/5

Which event principally restores the resting potential at a recently depolarized axonal site?

A. Fusion of synaptic vesicles with the axonal membrane
B. Continued unrestricted sodium entry
C. Entry of negatively charged proteins from outside
D. Increased potassium permeability and outward potassium movement

Example 2 · difficulty 3/5

Why does depolarization of one axonal segment initiate depolarization of the next segment?

A. Local circuit currents make the adjacent membrane permeable to sodium ions
B. Neurotransmitter is released continuously along the entire axon
C. Potassium ions entering the next segment reverse its polarity
D. The nucleus moves toward the next axonal segment

Example 3 · difficulty 3/5

Which sequence correctly represents events at one point of an axon during impulse generation and recovery?

A. Potassium influx, polarity reversal, sodium efflux, permanent depolarization
B. Sodium influx, polarity reversal, potassium efflux, restoration of resting polarity
C. Neurotransmitter release, sodium pump failure, protein efflux, repolarization
D. Potassium efflux, sodium influx, disappearance of all ionic gradients, resting state

Frequently asked questions

Are these official NEET 2025 Biology Neural Control and Coordination PYQs?

No. The previews are original NeetVellum practice questions. A historical item receives a PYQ label only after its official paper and authoritative final answer key are attached. Use the official archive for the source paper.

How should I use the NEET 2025 paper?

Solve the official paper under its original timing, verify against the final key, classify every miss, and then use the linked current-syllabus practice bank to repair the exposed concept.
