your muscle is only built to move your bone one way. you have two muscles for each action. for example, in order to move your arm, to move it up your bicep will contractand your tricep will not be working, to move it back down your bicep will then relax. in order to move your arm backwards your tricep will contract and your bicep will be relaxed and to return to its original state the tricep will relax. hope this helps.!!

Why are skeletal muscles often found in opposing pairs?

Which structure contains pairs of opposing skeletal muscles?

What is recipricol innervation in human body?
Reciprocal innervation refers to the coordinated activation of muscles on opposite sides of a joint. For example, when one set of muscles contracts to move a joint, the opposing muscles relax to allow for smooth movement. This mechanism helps in maintaining balance, stability, and coordinated movement in the body.
Are muscles that bend a joint called extensors?
Muscles that bend a joint are flexors; musces that straighten a joint are extensors.
Are Muscles that bend a joint called extensors and muscles that straighten a joint called flexors?
No, it is the opposite. Muscles that bend a joint are called flexors, while muscles that straighten a joint are called extensors. For example, the biceps are flexors of the elbow joint, and the triceps are extensors of the elbow joint.
Opposing joint movement for prone back extension?
Does problems in one joint cause problems in the opposing joint? Sounds logical but my doctor told me that arthritis in one joint is not the cause of arthritis in the opposing joint (knees) because people generally stay off both joints when having problmes with one. Is this logical? Len Krotzer
Why do muscles need to act as antagonistic pairs?
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.
