Arm flexion represents rotation in the anatomic plane such that the distal humerus moves ventrally. It represents raising the arm and isolated flexion can achieve approximately 150-170° of movement. The opposite movement is arm extension and contributes to the combined movement of shoulder circumduction.The words flexion and extension refer to how the shoulder muscles are moving in relation to how you move your arms. A shoulder flexion is when you move your arms anywhere from a resting position by your sides to straight above your head. An extension is when you move your arms and stick them out behind you.Forearm flexion is rotation in the anatomic plane such that the radius and ulna move anteriorly. It occurs primarily in the articulation between the humerus and ulna and can achieve approximately 150° of movement. It is the opposite of forearm extension. brachialis (primary)

What happens during arm flexion?
When your forearm moves toward your body by bending at your elbow, it’s called elbow flexion. The opposite movement is called elbow extension. The three bones involved in elbow flexion are the: humerus, in your upper arm.
Where does flexion occur in the arm?
Elbow and Wrist Joints
The elbow joint consists of the humerus, radius and ulna bones. The two main actions at the elbow are flexion and extension.
What is a good example of flexion?
Flexion – bending a joint. This occurs when the angle of a joint decreases. For example, the elbow flexes when performing a biceps curl. The knee flexes in preparation for kicking a ball.
What is flexion of the humerus?
Flexion: the movement of humerus straight anteriorly. Extension: the movement of humerus straight posteriorly. External rotation: the movement of humerus laterally around its long axis away from the midline. Internal rotation: the movement of humerus medially around its long axis toward the midline.
What is wrist flexion?
Wrist flexion is the action of bending your hand down at the wrist, so that your palm faces in toward your arm. It’s part of the normal range of motion of your wrist.

What muscles do elbow flexion?
There are different muscles involved in elbow flexion which are superficially biceps brachii and brachioradialis as well as deeper brachialis.
What is muscle flexion?
Flexion: decreasing the angle between two bones (bending). Extension: increasing the angle between two bones (straightening a bend). The triceps brachii and anconeus are muscles that extend the elbow. The biceps brachii, brachialis, and brachioradialis flex the elbow.
When you flex a muscle what happens?
Muscle flexing is more accurately known as muscle contraction, because when you flex your muscles, you’re creating tension that’s temporarily making the muscle fibers smaller or contracted.

What is flexion anatomy?
Flexion refers to decreasing a joint angle, and extension to increasing the joint angle back to resting anatomical position. Figure 1.
What is the meaning of flexion position?
Flexion is the medical term for bending an arm or leg. Techically speaking, it’s a physical position that decreases the angle between the bones of the limb at a joint. It occurs when muscles contract and move your bones and joints into a bent position.
Why is flexion movement important?
In the limbs, flexion decreases the angle between the bones (bending of the joint), while extension increases the angle and straightens the joint. For the upper limb, all anterior-going motions are flexion and all posterior-going motions are extension.
Which of the following motions are examples of flexion?
- Elbow flexion: bending the elbow to bring the forearm upward.
- Knee flexion: bending the knee to bring the lower leg upward.
- Shoulder flexion: lifting a straight arm up in front of the body.
- Trunk/back flexion: bending forward at the waist.
What muscle is responsible for flexing the arm?
Biceps Brachii: A muscle of the anterior compartment of the upper arm that flexes the forearm.
What is an example of shoulder flexion?
The most straightforward example of shoulder flexion is raising your arm straight up in front of you, but you actually use shoulder flexion in most pushing movements. Exercises such as push-ups, bench presses, dips and shoulder flexion all involve flexing the shoulder at different angles.
Which muscles flex the wrist?
The two important ones are flexor carpi radialis, and flexor carpi ulnaris.

What is lateral flexion of the neck?
Movement of a body part to the side is called lateral flexion. This type of movement is commonly associated with the neck and spine. For example, when you move your head toward one of your shoulders or bend your body sideways, you’re performing a lateral flexion.
