Muscle fibre is a syncitium as the sarcoplasm contains many nuclei. A characteristic feature of the muscle fibre is the presence of a large number of parallelly arranged filaments in the sarcoplasm called myofilaments or myofibrils. Each myofibril has alternate dark and light bands on it.

Understanding the Assertion and Reason
The assertion states that muscle fibers are a syncytium, while the reason given is that muscle fibers contain a large number of parallelly arranged myofilaments in the sarcoplasm.
What is a Syncytium?
- A syncytium is a multi-nucleated cell that results from the fusion of multiple cells.
- Muscle fibers, particularly skeletal muscle fibers, are indeed syncytial structures because they form from the fusion of myoblasts during development.
Role of Myofilaments
- Myofilaments (actin and myosin) are the contractile proteins found in muscle fibers.
- While their arrangement is crucial for muscle contraction, it does not define the syncytial nature of the muscle fiber.
Analysis of the Assertion
- The assertion that muscle fibers are a syncytium is true because they contain multiple nuclei per fiber, which is characteristic of a syncytium.
Analysis of the Reason
- The reason provided, that muscle fibers have a large number of parallelly arranged myofilaments, is true but does not explain why muscle fibers are syncytial.
- The arrangement of myofilaments is related to the function of muscle contraction, not the structural characteristic of being a syncytium.
Conclusion
- Since both the assertion and reason are true, but the reason does not explain the assertion, the correct answer is option 'B' – both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
