Original practice preview

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

Example 1 · difficulty 1/5

The resting membrane potential of a neuron is actively maintained by the sodium–potassium pump operating across the axolemma. The ratio in which this pump transports Na⁺ outwards to K⁺ inwards is:

  • A. 2 Na⁺ outwards : 3 K⁺ inwards
  • B. 1 Na⁺ outwards : 1 K⁺ inwards
  • C. 3 Na⁺ outwards : 2 K⁺ inwards
  • D. 3 K⁺ outwards : 2 Na⁺ inwards

Example 2 · difficulty 1/5

In a myelinated nerve fibre, the nerve impulse appears to leap from one point to the next along the axon. This saltatory conduction is possible because the voltage-gated ion channels are concentrated at the:

  • A. nodes of Ranvier
  • B. myelin sheath secreted by Schwann cells
  • C. synaptic knobs at the axon terminals
  • D. entire axolemma uniformly, as in unmyelinated fibres

Example 3 · difficulty 3/5

At a chemical synapse, impulse transmission involves a definite order of events: (i) neurotransmitter binds to receptors on the post-synaptic membrane, (ii) Ca²⁺ channels of the synaptic knob open and Ca²⁺ flows in, (iii) synaptic vesicles fuse with the pre-synaptic membrane and release the transmitter into the cleft, (iv) an action potential arrives at the axon terminal. The correct sequence is:

  • A. ii → iv → i → iii
  • B. iv → ii → iii → i
  • C. iv → iii → ii → i
  • D. i → ii → iv → iii

The evidence-first practice loop

  1. 1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
  2. 2. Attempt closed-bookExpose the concept or execution gap before rereading.
  3. 3. Repair and returnClassify the miss and re-practice after a delay.

Frequently asked questions

How many Neural Control and Coordination NEET questions are available?

NeetVellum currently publishes 250 original, verified questions across the linked canonical chapter.

How should I revise Neural Control and Coordination for NEET?

Attempt questions before rereading, classify each miss, repair the specific concept, and re-practice after a delay until the error pattern disappears.
