The correct Answer is:
To determine how many of the statements related to skeletal muscles are correct, we will evaluate each statement one by one. ### Step-by-Step Solution: 1. **Evaluate Statement I: "They are closely attached to bones."** - **Analysis:** Skeletal muscles are indeed attached to bones via tendons. They play a crucial role in movement by contracting and pulling on the bones. - **Conclusion:** This statement is **correct**. 2. **Evaluate Statement II: "These are involuntary in the activity."** - **Analysis:** Skeletal muscles are classified as voluntary muscles, meaning they can be consciously controlled. This statement incorrectly describes skeletal muscles. - **Conclusion:** This statement is **incorrect**. 3. **Evaluate Statement III: "They are typically found within the blood vessels."** - **Analysis:** Skeletal muscles are not found within blood vessels; instead, smooth muscles are present in the walls of blood vessels. This statement is misleading. - **Conclusion:** This statement is **incorrect**. 4. **Evaluate Statement IV: "Several muscle fibers are enclosed by a sheath of connective tissue."** - **Analysis:** This is true; skeletal muscle fibers are grouped together in bundles called fascicles, which are surrounded by a connective tissue sheath known as perimysium. - **Conclusion:** This statement is **correct**. ### Summary of Statements: - Statement I: Correct - Statement II: Incorrect - Statement III: Incorrect - Statement IV: Correct ### Total Correct Statements: Out of the four statements, **two statements (I and IV) are correct**. ### Final Answer: **2 statements are correct.** ---
