The injury would allow for the joint the muscles are attached to, to move in one direction...either only up becasue the lower muscle was damaged...or only down because the top muscle of the pair was damaged.
Muscles need to act as antagonistic pairs to create movement at a joint. One muscle contracts (agonist) to produce the desired movement, while the opposing muscle relaxes (antagonist) to allow the movement to occur smoothly and efficiently. This coordinated action helps stabilize the joint and prevent injury.
antagonistic muscle action.
The pectoralis muscle.
Heart muscle, or cardiac muscle, is not described as an antagonistic muscle because it functions differently from skeletal muscles, which work in pairs to create movement. Instead of opposing actions, cardiac muscle fibers contract rhythmically and simultaneously to pump blood throughout the body. This coordinated contraction is essential for maintaining a consistent heartbeat, ensuring efficient blood circulation without the need for antagonistic pairs.
muscles that work in opposition to each other
Antagonistic muscle pairs. That means to work in opposition to each other.One muscle produces movement in one direction and the other muscle produces movement in the opposite direction. It would seem to be contradictory but a very smooth movement occurs when they work this way.
When one muscle pulls, the other muscle relaxes.
for biceps it is triceps
Antagonistic muscles work together in pairs to produce movement in opposite directions around a joint. When one muscle contracts, its counterpart relaxes, allowing for coordinated and smooth movement. This arrangement helps stabilize the joint and ensures efficient movement. An example is the biceps and triceps in the arm, which work together to bend and straighten the elbow.
antagonistic muscles
because you suck
The muscle that is primarily responsible for bringing about a particular movement is called the prime mover or agonist muscle. It is the main muscle that contracts to create the desired movement at a joint. Antagonist muscles work in opposition to the prime mover to control the movement and prevent injury.
