The arm can perform a variety of movements, including flexion and extension at the elbow, allowing it to bend and straighten. It can also move in a circular motion due to shoulder rotation, enabling actions like waving or throwing. Additionally, the arm can perform abduction and adduction, moving away from and toward the body, respectively. These movements are facilitated by various muscles and joints working together.
The supinator muscle is a muscle in the forearm that is not directly responsible for flexion or extension of the arm. Its primary function is to rotate the forearm in a movement called supination, where the palm faces up.
Lifting your arm away from your body is abduction
abduction
The medial roataion is the movement of Glenohumeral joint .
Flexion is the movement of decreasing the angle between two body parts, such as bringing the arm closer to the shoulder. Abduction is the movement of a body part away from the midline of the body, such as moving the arm out to the side.
extention
movement
The biceps muscle relaxes!!!!!=)

The arm is engaged in a motion called flexion when moving from position A to position B. This involves reducing the angle between the bones of the arm at a joint, such as the elbow or shoulder.

When you make a muscle in your arm, you are flexing your biceps brachii, which is located in the front of your upper arm. This muscle contracts to bend your elbow and bring your forearm closer to your shoulder. Additionally, the triceps muscle, located at the back of your upper arm, relaxes to allow this movement. Together, these muscles work to enable various arm movements.
To accurately answer your question about the Arm's movement from position B, I would need more context regarding the specific positions or actions involved. Generally, arm movements can involve flexion, extension, abduction, adduction, or rotation, depending on the transition between the positions. Please provide additional details about position B or the nature of the movement for a more precise response.
No, it shouldn't make any kind of peculiar noise at all.
Snakelike or fish like movements.

The biceps flexes the arm it does not extend it (straightens). The triceps brachii extends the arm. They do work together. If one is damaged and doesn't work as it should, the movement will be "jerky" and not smooth.
