Original practice preview

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

Example 1 · difficulty 3/5

The osmolarity of the medullary interstitial fluid in the human kidney increases from the cortex towards the inner medulla. The maximum osmolarity that the inner medullary interstitium can attain is about:

A. 300 mOsmol L⁻¹
B. 600 mOsmol L⁻¹
C. 900 mOsmol L⁻¹
D. 1200 mOsmol L⁻¹

Example 2 · difficulty 1/5

The coordinated movements of hair-like cellular outgrowths lining the trachea help in expelling dust particles inhaled along with air. This form of movement is called:

A. Flagellar movement
B. Amoeboid movement
C. Ciliary movement
D. Muscular movement

Example 3 · difficulty 2/5

In a fully relaxed sarcomere viewed under the electron microscope, the lighter-staining region composed exclusively of thin (actin) filaments is the:

B. A-band
C. M-line
D. I-band

Frequently asked questions

Are these official NEET 2026 Biology Human Physiology 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 2026 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.
