it contracts while the other one relaxes
Dorsi flexion and eversion are its main actions. I just can't justify this your question.
The agonist muscle for wrist flexion is the flexor carpi radialis, while the antagonist muscle is the extensor carpi radialis longus. These muscles work in opposition to produce movement at the wrist joint.
A flexor is a type of muscle that serves to bend a joint or limb when it contracts. It is responsible for bringing two body parts closer together. The main function of flexors is to facilitate movement, such as bending your elbow or knee.
The primary flexor of the hip is the Illiopsoas. Or more specifically the Psoas Major which originates transverse processes T12 to L5 of the vertebral column and Inserts onto the Lesser Trochanter of the femur.
An example of a flexor muscle is the biceps brachii in the upper arm. Its function is to bend the arm at the elbow joint, allowing for movements like lifting and curling.
Extensor muscles open a joint and are the opposite to flexor muscles, which close it. I imagine triceps are extensor, while biceps are flexor.
Extensor muscles help to straighten or extend the joint while flexors do the opposite, bending it.
Triceps muscle is not a flexor. Triceps is an extensor of elbow joint. Biceps muscle is flexor.
All skeletal muscles will have a flexor and an extensor. The flexor bends the joint. The extensor straightens it out again.
Yes. Skeletal muscles will have a flexor and an extensor. The flexor bends the joint. The extensor straightens it out again.

Extensor muscles open a joint and are the opposite to flexor muscles, which close it. I imagine triceps are extensor, while biceps are flexor.
The flexor bends the joint, and since the flexor cannot lengthen by itself to push the bone back to straighten the joint, the extensor pulls the bone in the opposite direction. Tendons attach muscles to bones and helps the chicken move its wing.

No the flexor closes the joint.
extensorThe triceps brachii is an extensor. It is the large muscle on the back of the arm and is primarily the muscle used for extension of the elbow joint or straightening of the arm. The triceps is also an antagonist of the biceps and the brachialis muscles.ExtensorsTriceps is not a flexor. It is extensor of the elbow joint.
When bones attached to a muscle are connected by a flexible joint, contraction of the muscle moves the skeleton. The muscle is called a flexor if the centers of the connected bones are brought closer together when the muscle contracts, and the movement is called flexion. (Biceps)The muscle is called an extensor if the bones move away from each other when the muscle contracts, and the movement is called extension. (Triceps)
