Original practice preview

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

Example 1 · difficulty 2/5

How does the resting axonal membrane differ in permeability to potassium and sodium ions?

A. It is more permeable to sodium and impermeable to potassium
B. It is more permeable to potassium and nearly impermeable to sodium
C. It is equally and freely permeable to both ions
D. It is completely impermeable to every ion

Example 2 · difficulty 2/5

During each cycle, how does the sodium-potassium pump move ions across the axonal membrane?

A. Three potassium ions outward and three sodium ions inward
B. Two sodium ions outward and three potassium ions inward
C. Three sodium ions outward and two potassium ions inward
D. One sodium ion inward and one potassium ion outward

Example 3 · difficulty 1/5

What is the approximate resting membrane potential of an axon stated in NCERT?

A. −7 V
B. +70 mV
C. 0 mV
D. −70 mV

Frequently asked questions

Are these official NEET 2023 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 2023 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.
