Flexor and extensor muscles basically do opposite jobs: flexors contract to "close" a joint whereas extensors lengthen to "open" a joint.
Sets of flexors and extensors are attached to the same joints, which means that there is a relationship between how they work. In smooth, efficient movement activity in the flexors will also cause inhibition in the extensors (and vice versa). If this weren't the case, the muscles would be working against each other which would not provide efficient movement, and can actually cause damage to the body.
Due to faulty movement learning, many people unfortunately have less than perfect cooperation between their flexors and extensors, and it is a common cause of chronic pain and inflammation.

Do skeletal muscles work in paires?
All skeletal muscles will have a flexor and an extensor. The flexor bends the joint. The extensor straightens it out again.
Do most skeletal muscles work in antagonistic pairs?
Yes. Skeletal muscles will have a flexor and an extensor. The flexor bends the joint. The extensor straightens it out again.

extensor
Is the shin a flexor or extensor?
Extensor
How the flexor and extensor work together to move the lower wing and bend the joint between the upper and lower wing?
The flexor muscle contracts and shortens to bend the joint, moving the lower wing up towards the upper wing. The extensor muscle then relaxes to allow this movement. The coordinated action of the flexor and extensor muscles allows for controlled movement of the wings.
What is the primary extensor of the wrist and fingers?
The extensor digitorum communis is an extensor of the wrist and fingers. The extensor digitorum communis is the primary extensor of the lateral four fingers IP joint and assists in wrist extension.
