Skeletal muscle fibre is a "Syncytium" which means it is

Options

A. Made up of many fibres
B. Made up of many proteins
C. Long and slendar
D. Multinucleated.

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Term "Syncytium":**
- A syncytium refers to a tissue structure where multiple cells fuse together to form a single cell with multiple nuclei. This is a characteristic feature of skeletal muscle fibers.

2. **Characteristics of Skeletal Muscle Fibers:**
- Skeletal muscle fibers are long, cylindrical cells that can be several centimeters in length. They are multinucleated, meaning they contain multiple nuclei within a single cell.

3. **Formation of Syncytium in Skeletal Muscle:**
- During development, myoblasts (the precursor cells of muscle fibers) fuse together to form these long, multinucleated fibers. This fusion is what gives skeletal muscle its syncytial nature.

4. **Functional Implications of Syncytium:**
- The syncytial structure allows for coordinated contraction of the muscle fibers. The presence of multiple nuclei helps in the synthesis of proteins and other cellular components necessary for muscle function.

5. **Conclusion:**
- Therefore, when we say that skeletal muscle fiber is a "syncytium," we mean that it is a multinucleated structure formed by the fusion of individual muscle cells (myoblasts), which enables efficient muscle contraction.
