Probably the Biceps Brachii (commonly called Biceps).
A flexor is a muscle that causes a joint to bend. In contrast, an extension is a muscle that straightens a joint.
The muscle/muscles that bend your arms are called Flexor and Extensor.
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 wrist is bent by the wrist flexor muscles, including the flexor carpi radialis, flexor carpi ulnaris, and palmaris longus. These muscles are responsible for flexing the hand at the wrist joint.
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.
Triceps muscle is not a flexor. Triceps is an extensor of elbow joint. Biceps muscle is flexor.
flexor digitorum superficialis
The flexor would be the hamstring, and gastrocnemius, which bend/flex the knee. The quadriceps, are extensors, which straighten/extend the knee.
The quadriceps muscle helps straighten and extend the leg and the hamstring helps bend the knee.
The major spine flexor is the rectus abdominis muscle. It runs along the front of the abdomen and helps to bend the spine forward. It is commonly known as the "abs" muscle and is important for activities like sit-ups and crunches.
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.
