Latissimus Dorsi
The prime mover for pulling the arm posteriorly is the latissimus dorsi muscle. This large muscle spans the lower back and attaches to the upper arm bone, allowing it to bring the arm backward when contracted. It is commonly utilized during movements like pulling, rowing, and swimming.
The latissimus dorsi muscle is the prime mover for pulling the arm posteriorly. It is a large muscle that originates from the lower back and inserts into the upper arm bone, allowing for powerful movements like pulling and reaching behind the body.
The latissimus dorsi muscle is responsible for pulling the arms backward. It is a large muscle that spans the back and attaches to the upper arm bone, allowing it to perform movements like pulling and reaching.
When you pull a window shade, you exert a force known as tension. This tension force is applied to the part of the shade that you are pulling, causing it to move in the desired direction. The tension force comes from your arm muscles or any mechanism that is attached to the shade for pulling.
You can make a mousetrap turn by attaching a string or wire to the arm of the mousetrap and pulling it in the desired direction. Another way is to place the mousetrap on a rotating surface, such as a lazy susan, and spin it to make it turn.

Pectoralis major
triceps brachii
The arm of a generator is turned by a prime mover, such as a steam turbine, water turbine, or internal combustion engine. The motion provided by the prime mover is transferred to the armature through a shaft, causing it to rotate within the magnetic field of the stator which generates electricity.
The latissimus dorsi is the muscle responsible for moving the arm posterior or backwards.
Prime mover is the bicep and the antagonist is the tricep.
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.
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.
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.
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
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.
