Read the following statements about animal tissues : A. The smooth muscle muscle fibres are non-striated, fusioform shape and hold together by cell junctions.
B. Cardiac muscle is structurally similar to smooth muscle and acts similar to skeletal muscle.
C.The skeletal muscle is the only multinucleate and voluntary muscles with alternate light and dark striations .

Options

A. A and B are correct , C is incorrect
B. A is incorrect, B and C are correct
C. A and C are correct , B is incorrect
D. A is correct , B and C are incorrect

Answer

To analyze the statements about animal tissues, we will evaluate each statement one by one.

### Step 1: Evaluate Statement A
**Statement A:** "The smooth muscle fibers are non-striated, fusiform shape and hold together by cell junctions."

- **Analysis:** Smooth muscle fibers are indeed non-striated, which means they do not have the alternating light and dark bands seen in striated muscles. They are also fusiform in shape, meaning they are tapered at both ends. Additionally, smooth muscle fibers are connected by cell junctions, which allow for coordinated contractions.

- **Conclusion:** Statement A is **correct**.

### Step 2: Evaluate Statement B
**Statement B:** "Cardiac muscle is structurally similar to smooth muscle and acts similar to skeletal muscle."

- **Analysis:** Cardiac muscle is not structurally similar to smooth muscle. Cardiac muscle fibers are striated (like skeletal muscle) and branched, while smooth muscle fibers are non-striated and fusiform. Although cardiac muscle does function involuntarily (like smooth muscle), it is structurally more similar to skeletal muscle due to the presence of striations.

- **Conclusion:** Statement B is **incorrect**.

### Step 3: Evaluate Statement C
**Statement C:** "The skeletal muscle is the only multinucleate and voluntary muscle with alternate light and dark striations."

- **Analysis:** Skeletal muscle is indeed multinucleate, meaning it has multiple nuclei per cell. It is also voluntary, meaning its contractions are under conscious control. The presence of alternating light and dark striations is a defining characteristic of skeletal muscle.

- **Conclusion:** Statement C is **correct**.

### Final Conclusion
- **Correct Answers:** A and C are correct; B is incorrect.

### Summary of Findings:
- **Statement A:** Correct
- **Statement B:** Incorrect
- **Statement C:** Correct
