Answer:
The triceps muscle extends when the biceps muscle is contracted.
Explanation:
The biceps and triceps muscles,work together in creating functional movement. These movements contribute to the ability to perform day to day tasks.
These muscles function in flexing and extending the arm. <em>Biceps for flexion</em> and<em> triceps for extension</em>. Both muscles work in an antagonistic fashion such that, the one doing the major motion is called the <em>primary mover</em> while the other muscle, is the <em>antagonist</em>. These muscles work in opposite direction, aiding the movement of the arm in both directions.
When biceps are contracted, the triceps are extended. Their antagonistic nature is beneficial because both muscles set the motion patterns at particular points. If we only had biceps extension of the elbow will be impossible and any movement that requires extension would not have been possible and vice versa.
You have to remember that a scientific hypothesis is a question about whether or not something will happen the way you think it will.
