which two structures make up the muscular system?\n○ muscles and bones\n○ muscles and ligaments\n○ muscles and tendons\n○ muscles and joints
Answer
Brief Explanations:
To determine the two structures of the muscular system, we analyze each option:
- "Muscles and bones": Bones belong to the skeletal system, not the muscular system. Eliminate this.
- "Muscles and ligaments": Ligaments connect bones and are part of the skeletal system's support, not the muscular system. Eliminate this.
- "Muscles and tendons": Tendons connect muscles to bones, and together with muscles, they form the muscular system (muscles for contraction, tendons for attachment). This is correct.
- "Muscles and joints": Joints are where bones meet (skeletal system), not part of the muscular system. Eliminate this.
Answer:
C. muscles and tendons
