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.

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.
Blinking ;)
Snakelike or fish like movements.
No, it shouldn't make any kind of peculiar noise at all.

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.
arm movement: face backs of hands towards each other and push out wards ( like if you were parting some vines) leg movement: outwards and back in a circular motion in the water. Your whole body goes underwater, you do the arm movement and leg movement,c ome up, take breath, repeat. Sorry, kind of vague, feel free to improve my answer.
No, and the muscle that controls the movement is the piloerector muscle. See piloerector which are smooth muscle (involuntary)
