Which muscle is the prime mover for arm abduction?

Name the prime mover that flexes the forearm at the elbow?
It's bicep muscle.Actually its the Brachialis muscle that is the prime mover to flex the upper limb at the elbow. The biceps brachi (leymen: biceps) is only a helper and only when the arm is suppinated, suppination being the biceps primary function. Technically the arm is only the region of the upper limb between the shoulder and the elbo and thus flexion of the arm actually means lifting the humerus up and forwards. The muscles that contribute to this movement are the Clavicular part of the deltoid, clavicular head of pectoralis major, and there is a slight input from coracobrachialisNO the biceps muscle flexes the forearm (the elbow joint). The Pectoralis major is the prime mover of arm flexion. I am getting this right out of my lab book.
What is a fixation of a muscle?
The functions of a fixator muscle is the stabalizing of the orgin of the prime mover so that the prime mover can act more efficiently. Fixators steady the proximal end of a limb while movements occurs at the distal end. EX: The scapula is a freely movable bone that serves as the orgin for several muscles that move the arm. When the arm contracts the scapula must be held steady.
The trapezius is the prime mover for most movements of the?
The trapezius muscle extends from the upper back to the back of the neck. Its main functions are to support the arm and to move the shoulder blade.
What is the prime mover of a bicep curl?
the bicep contracts in a concentric contraction which means the muscles has shortened. remember muscles can only pull they can not push. also the bicep curl can be described as elbow flexion and when the weight is lowered is called elbow extention. hope it helps
Is the deltoid a mover of the arm that acts in adduction?
Yes. Deltoid (Delta like.) is the prime mover of arm. It moves shoulder joint in forward, backward and laterally. It is a continuation ofTrapeziusmuscle. It is 'not' mentioned in any anatomy books. But you can verify it. Trapezius is inserted in inner side of clavicle and spine of scapula and from outer side of the same Deltoid muscle starts.
Which muscles straighten the arm?
no it isnt because the arm is bent by the flexor muscles (mostly just the biceps), and straightened by the extensor muscles (ie. the triceps).
