Sample item

Which receptors detect muscle length changes?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. Muscle spindles

Muscle spindles lie within skeletal muscle and detect changes in muscle length and stretch velocity, supporting reflex control of posture.

Option by option

  • A. Golgi tendon organs

    Golgi organs sense tendon tension.

  • B. Pacinian corpuscles

    Pacinian corpuscles sense vibration.

  • C. Muscle spindles (correct)

    Correct: spindles sense stretch.

  • D. Free nerve endings

    Free endings detect pain and temperature.

What is the answer to this Physiology question?

The best answer is C, Muscle spindles. Muscle spindles lie within skeletal muscle and detect changes in muscle length and stretch velocity, supporting reflex control of posture.

Why is "Golgi tendon organs" not the answer?

Golgi organs sense tendon tension.

Why is "Pacinian corpuscles" not the answer?

Pacinian corpuscles sense vibration.

Why is "Free nerve endings" not the answer?

Free endings detect pain and temperature.

What concept does this question test?

It tests Sensory physiology in Physiology. The correct option holds because: Correct: spindles sense stretch.

How hard is this question?

We tag it as an application question: it asks you to use a fact on a patient or a finding. The tag is our own editorial judgement, not an official difficulty rating, so read the reason for every option, not only the answer.

How should I study Sensory physiology?

For each system, sketch the key graph (pressure–volume loop, oxygen dissociation curve, nephron handling) and explain it aloud. Then use the flashcards and the other Physiology questions on this site to test what stuck.

Is this a real NEET PG question?

No. It is an original practice item (editorial status: sample, version 1). NextPrep does not publish recalled or leaked questions, and independent faculty review of this item has not been completed yet, so confirm important facts in a standard textbook.
