Free Sneak Peek

Here is a sneak peek of the questions included in this test set. Test your preparation by viewing the answer and detailed explanation before starting the timed exam.

Q1
During continuous high-frequency stimulation, why does an action potential travel strictly unidirectionally along an axon?
सतत उच्च-वारंवारतेच्या उत्तेजनेदरम्यान, अ‍ॅक्सॉनवर क्रिया विभव (Action potential) केवळ एकाच दिशेने का प्रवास करतो?
A
Due to the absolute refractory period of upstream sodium channels
B
Because myelin sheath absorbs backward currents
C
Due to rapid hydrolysis of acetylcholine in the axoplasm
D
Because potassium channels open only in a backward direction
Correct Answer: Option A
Explanation:
Action potentials travel unidirectionally because the patch of axonal membrane behind the impulse is in an absolute refractory period with inactivated Na+ channels.
ज्या भागातून आवेग नुकताच पुढे गेला आहे, तेथील व्होल्टेज-गेटेड Na+ चॅनेल्स तात्पुरते अकार्यक्षम (Refractory period) असतात, ज्यामुळे आवेग मागे फिरू शकत नाही.
Q2
Saltatory conduction of nerve impulses is characteristic of myelinated nerve fibers because:
मायलिनयुक्त चेतातंतूंमध्ये उडी मारत होणारे वहन (Saltatory conduction) वैशिष्ट्यपूर्ण असते, कारण:
A
Schwann cells actively generate independent electricity
B
Action potentials are generated exclusively at the uninsulated Nodes of Ranvier
C
Current leaks uniformly along the fatty myelin sheath
D
Neurotransmitters are secreted directly across the axon shaft
Correct Answer: Option B
Explanation:
Myelin sheath acts as an electrical insulator; ionic depolarization can only occur at unmyelinated gaps called Nodes of Ranvier, causing the impulse to 'jump'.
मायलिन आवरण विद्युत निरोधक असल्याने आयनांची देवाणघेवाण फक्त रॅनव्हिअरच्या गाठींवरच होते, त्यामुळे आवेग एका गाठीवरून दुसऱ्या गाठीवर उडी मारल्यासारखा वेगाने वाहतो.

How Chapter-Wise Online CBT Tests Build Winning Habits for Future Competitive Exams

Focused chapter-wise CBT practice builds the speed, mental stamina, and analytical discipline required to ace CUET, JEE Main, NEET UG, NDA, CA Foundation, and College Entrance Exams.

Competitive Edge

Real-Time Clock Awareness & Pacing

समय प्रबंधन एवं गति नियंत्रण

In school examinations, students write answers without active pacing. In national entrance tests, students have barely 45-60 seconds per MCQ. Practicing with a 20-minute timer instills instinctive time-budgeting and prevents last-minute exam panic.

Mastery of the Elimination Technique

विकल्प निष्कासन विधि में दक्षता

Top rankers in competitive exams rarely compute every problem blindly. They spot subtle traps, evaluate extreme values, and eliminate 2 out of 4 distractors within seconds. Our 4-option sets teach critical distractor analysis.

CBT Screen Stamina & Digital Comfort

कंप्यूटर आधारित परीक्षा का सहज अभ्यास

Almost all major national exams (CUET, JEE, NEET, SSC, Banking) are 100% computer-based. Students who only study on paper experience eye strain and navigation mistakes on exam day. Early CBT practice creates effortless digital fluency.

Immunity to Negative Marking

सटीकता और नकारात्मक अंकन से सुरक्षा

Careless errors—such as misreading "NOT" or "EXCEPT"—ruin thousands of competitive aspirations each year. Regular objective testing builds the habit of double-checking question keywords before locking answers.

Instant Diagnostic Feedback Loop

तत्काल त्रुटि निवारण एवं आत्म-मूल्यांकन

Traditional paper tests take weeks to grade, by which time the student has forgotten their thought process. TargetExams provides instant scorecards and step-by-step solutions while the conceptual puzzle is still fresh.
