Hint: The biceps and triceps muscles work together to permit you to bend and straighten your elbow. Once you want to bend your elbow, your biceps muscle contracts and, at an equivalent time, the triceps muscle relaxes. The biceps are the flexor, and therefore the triceps are the extensor of your elbow.
Complete Answer:
A muscle can pull a neighborhood of the body by its contraction. The body muscles are arranged in antagonistic pairs. Muscles during a pair move the part in one direction and another within the other way. For instance, the muscle named bicep brings the forearm towards the upper arm, and therefore the muscle called the tricep to maneuver the forearm faraway from the upper arm.
So, the assertion is correct.
As the biceps contract to cause movement, the triceps relax to permit the movement to occur and the other way around. This is often the flexor and extensor quiet muscles. Muscles that bend one part over another joint is understood as a flexor. extensor is an antagonist which contracts cooling one among the articulated bones aside from another.
So, the rationale is correct.
Thus, the right answer is (A) If both assertion and reason are true and therefore the reason is that the correct explanation of assertion.
Note: Antagonistic muscles are those muscles, which contract to supply opposite movements at an equivalent joint. When a muscle contracts to maneuver, its antagonist must relax to permit the movement to require place. Biceps and triceps are called antagonistic muscles. Because during flexion at the elbow, biceps contract and triceps relaxes, during extension at an equivalent joint, triceps contract, and biceps relax.
