The raising of the arm can be divided into three phase. The initial phase is carried out by the supraspinatus muscle. After the arm as been raised to 30 degrees, the deltoid muscle takes over. This muscle performs this action until the horizontal plane. In the last phase, the serratus anterior raises the arm above the horizontal plane.
So the answer to your question is the supraspinatus muscle, deltoid muscle, and the serratus anterior muscle.
Primarily the deltoids, however the trapesius', biceps and triceps all play minor roles depending on whether the movement of the arm is abduction, flexion or extension, and also the plane in which it was raised.
Triceps, deltoids, biceps, I know all this
Bicep muscles on the front of the upper arm
lateral deltoid
They are pushed by tendons.
You can find me in the shoulder. I raise and rotate the arm. My name is Deltoid
The biceps brachii muscle will contract, pulling the lower arm up.
To raise your hand in class, by bending your arm at the elbow.
Arm
A muscle doesn't rotate the shoulder. The ligaments that connect your shoulder blade to your arm, to your rib cage all work in a ball and socket type of way allowing you to rotate your arm 360o.
There is not a single muscle that rotates the upper arm. The name of the muscle that contributes in rotation of the upper arm is deltoid muscle.
Skeletal muscle is associated with the upper arm.
The brachialis is a muscle in the upper arm that flexes the elbow joint.
What are the tendon in your arm?
no
Biceps or triceps
where you bored when you posted this question or have you pop you muscle in you left arm
