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. Biceps for flexion and triceps for extension. Both muscles work in an antagonistic fashion such that, the one doing the major motion is called the primary mover while the other muscle, is the antagonist. 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.
When the triceps muscle is contracted, the biceps muscle is stretched, the reverse being the case. Even though these muscles are antagonistic, so it can be beneficial in helping muscle balance and stretched arm structure.
What happens when the biceps contract?
When the biceps contract, pulling on the forearm, the muscle fibers shorten. And exactly the opposite happens with the triceps muscle (which is under the arm), as it is the muscle that contracts when the arm extends and relaxes when there is flexion.
With this information, we can conclude that when the triceps muscle is contracted, the biceps muscle is stretched, the opposite being the case. Even though these muscles are antagonistic, it can be beneficial to help with muscle balance and straight arm structure.
