Which one of the following statements is incorrect about muscles in hu...
The correct answer is Muscles can only push the bone.
Key Points
- Muscles are part of the human skeletal system.
- Myofibers form muscles and parallel bundles of myofibrils form these muscles.
- Muscles consist of various proteins such as actin, myosin, troponin, and tropomyosin.
- It helps in locomotion.
- Muscles can pull not push.
- It is because muscles contract with the help of proteins actin and myosin.
- Muscles work in pairs.
- One muscle contracts and the other relaxes, thus working in pairs.
- Muscles get shorter, stiffer, and thicker when contracted.
- The length of sarcomere shortens while contracting.
- Muscles become longer and thinner while relaxing.

Explanation:
Muscles in human body are complex structures that play a crucial role in movement and stability. Let's break down the incorrect statement and explain why it is wrong:
Pushing and Pulling:
- Muscles in the human body can both push and pull bones. While some muscles, like the triceps, primarily function to push bones away from the body, other muscles, like the biceps, work to pull bones towards the body. Therefore, muscles can perform both pushing and pulling actions.
Muscles Working in Pairs:
- Muscles in the human body work in pairs to create movement. One muscle in the pair contracts to move a bone in one direction, while the other muscle in the pair relaxes. For example, the biceps and triceps in the arm work together to flex and extend the elbow joint. This coordinated effort of muscles in pairs allows for smooth and controlled movement.
Changes in Muscle Length and Thickness:
- When a muscle contracts, it becomes shorter, stiffer, and thicker. This contraction occurs due to the sliding of actin and myosin filaments within the muscle fibers. The shortening of the muscle fibers results in movement of the attached bones. Thus, muscles do not simply push bones, but they generate force through contraction to produce various movements.
Therefore, the correct statement is that muscles in the human body can both push and pull bones, not just push them. This highlights the versatility and dynamic nature of muscles in facilitating movement and maintaining posture.
