In the context of muscle anatomy, what are paired muscles?

• A. Muscles that are located on opposite sides of the body and perform opposite actions
• B. Muscles that are attached to the same bone
• C. Muscles that work together to perform the same function
• D. Muscles that are innervated by the same nerve

Answer: (A)

Verified step by step guidance

1. Understand the concept of paired muscles in anatomy. Paired muscles are typically located on opposite sides of the body and perform opposite actions, such as flexion and extension.
2. Consider the anatomical arrangement of muscles. Paired muscles are often found in symmetrical positions, such as the biceps and triceps in the arms, which perform opposite actions.
3. Evaluate the options given: Muscles that are located on opposite sides of the body and perform opposite actions, Muscles that are attached to the same bone, Muscles that work together to perform the same function, Muscles that are innervated by the same nerve.
4. Analyze each option: The first option describes muscles that are anatomically and functionally paired, such as antagonistic muscle pairs. The second option refers to muscles sharing a common attachment point, which is not specific to paired muscles. The third option describes synergistic muscles, which work together rather than oppositely. The fourth option refers to muscles sharing nerve supply, which is unrelated to the concept of paired muscles.
5. Conclude that the correct description of paired muscles is the first option: Muscles that are located on opposite sides of the body and perform opposite actions.
