What is the prime mover for pulling the arm posteriorly?
The prime mover for pulling the arm posteriorly is the latissimus dorsi muscle. It is a large muscle that originates in the lower back and attaches to the upper arm bone. When the latissimus dorsi contracts, it helps to pull the arm towards the back of the body.
What muscle is the prime mover for pulling the arm posteriorly?
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.
What muscle pulls arms backward?
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 exert what force?
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.
What type lever of coracobrachialis?
The coracobrachialis muscle acts as a third-class lever in the body. It helps flex and adduct the arm at the shoulder joint by pulling on the coracoid process of the scapula when contracting.

What is the prime mover for arm flexion?
Pectoralis major
What muscle of the arm that is the prime mover of forearm extension?
triceps brachii
What Turns the arm of a generator?
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.
Which muscle is the prime mover for arm abduction?
The latissimus dorsi is the muscle responsible for moving the arm posterior or backwards.
Prime mover for shoulder flexion?
Prime mover is the bicep and the antagonist is the tricep.
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.
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.
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 a muscle that immobilizes a bone or a muscle's organ so that the prime mover has a stable base in which to act?
The muscle that immobilizes a bone or a muscle's organ to provide a stable base for the prime mover is known as a stabilizer or fixator. These muscles contract isometrically to maintain posture or position, allowing the prime mover to perform its action efficiently. For example, during a bicep curl, the shoulder muscles act as stabilizers to keep the upper arm steady while the biceps contract to lift the forearm.
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
