Q1
What is the SARCOMERE in skeletal muscle and what are its boundaries?
कंकाल पेशी में 'सार्कोमियर' (Sarcomere) क्या है और इसकी सीमाएं क्या होती हैं?
A
The region between two M-linesदो एम-लाइनों के बीच का क्षेत्र
B
The structural and FUNCTIONAL UNIT OF MUSCLE CONTRACTION; the portion of a myofibril between TWO SUCCESSIVE Z-LINES (consisting of 1 A-Band and 2 half I-Bands)पेशी संकुचन की क्रियात्मक इकाई; दो क्रमागत Z-रेखाओं (Z-lines) के बीच का भाग
C
The neuromuscular junctionन्यूरोमस्कुलर जंक्शन
D
The whole muscle bundle surrounded by epimysiumसंपूर्ण मांसपेशी बंडल एपिमिसियम से घिरा हुआ है
Correct Answer: Option B
Explanation:
A myofibril has dark and light bands: The light bands contain ACTIN and are called I-band (Isotropic band), bisected by an elastic fibre called Z-LINE. The dark bands called 'A' or Anisotropic band contain MYOSIN, held at the center by a thin fibrous membrane called M-line. The portion of the myofibril between two successive Z-lines is considered as the functional unit of contraction and is called a SARCOMERE.
दो Z-रेखाओं के बीच का भाग सार्कोमियर कहलाता है।
Q2
What is the SLIDING FILAMENT THEORY of muscle contraction (proposed by Huxley and Hanson)?
हक्सले का पेशी संकुचन का 'सर्पी तंतु सिद्धांत' (Sliding Filament Theory) क्या बताता है?
A
Z-lines move away from each otherZ-लाइनें एक दूसरे से दूर जाती हैं
B
Myosin filaments shorten while actin length increasesमायोसिन तंतु छोटे हो जाते हैं जबकि एक्टिन की लंबाई बढ़ जाती है
C
A-band disappears completely during contractionसंकुचन के दौरान ए-बैंड पूरी तरह से गायब हो जाता है
D
Contraction occurs by the SLIDING OF THIN (ACTIN) FILAMENTS OVER THICK (MYOSIN) FILAMENTS towards the center of A-band; I-BANDS SHORTEN, H-ZONE DISAPPEARS, while A-BAND LENGTH REMAINS UNCHANGEDपतले एक्टिन तंतुओं का मोटे मायोसिन तंतुओं पर फिसलना; I-बैंड व H-क्षेत्र छोटा होता है जबकि A-बैंड की लंबाई अपरिवर्तित रहती है
Correct Answer: Option D
Explanation:
Mechanism of muscle contraction: (1) Sliding filament theory states that contraction of a muscle fiber takes place by the sliding of thin (actin) filaments over the thick (myosin) filaments; (2) The actin filaments attached to Z-lines are pulled towards the center of A-band (H-zone reduces/disappears); (3) The I-bands get reduced in length, Z-lines move closer (sarcomere shortens); (4) The A-BANDS RETAIN THEIR LENGTH.
पेशी संकुचन में A-बैंड की लंबाई स्थिर रहती है, I-बैंड घटता है।

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.
