brachialis
Prime mover is the bicep and the antagonist is the tricep.
The prime mover for knee flexion is biceps femoris, semimembranosus, and semitendinosus. The prime mover for knee extension is the Quadriceps â?? vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris
Triceps brachiiElbow flexion is due to the contraction of the biceps brachii, the prime mover. The triceps brachii extends as the biceps brachii contracts and therefore is the antagonist muscle.
The prime mover of elbow flexion is the biceps brachii, which contracts to bend the elbow. The antagonist, which opposes this movement, is the triceps brachii, as it extends the elbow. During elbow flexion, the biceps brachii shortens while the triceps brachii lengthens, allowing for smooth movement.
prime mover (agonist)Not sure what you're asking here, but the biceps brachii is the prime mover facilitating flexion at the elbow joint.
A prime mover, or agonist, is the primary muscle responsible for a specific movement, while an antagonist opposes that movement. In certain contexts, a muscle can act as both a prime mover and an antagonist, depending on the movement being performed. For instance, during a bicep curl, the biceps are the prime movers for elbow flexion, but they can also act as antagonists when extending the elbow, helping to control the movement and stabilize the joint. This dual role is essential for coordinated and smooth muscle function during dynamic activities.
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 Main muscles used when you do elbow curls are the bicep muscles.
Tiil adidas is the prime mover of ankle plantar flexion.
Shoulder extension is controlled by: Long head of the triceps, the last, and the teres major
It depends on your position and if you are moving with or against gravity. If you are standing up right in anatomical position, and elbow extension is occurring after elbow flexion, then it is eccentric. When the elbow is moving into extension from flexion, it is moving downwards with the force of gravity. In order for this motion to occur, the biceps brachii has to lengthen, and the triceps brachii has to relax. The biceps brachii therefore is your primary mover. If elbow extension were occurring against the force of gravity (imagine your shoulder is flexed to 180 and your elbow is flexed, and you want to move it into extension while your shoulder is still flexed at 180), then it would be a concentric contraction and your primary mover would be your triceps brachii as it would be shortening to complete the motion. The biceps brachii would be your antagonist and it would be relaxing to allow the triceps to do its work. concentric= muscle shortening eccentric= muscle lengthening I hope this helps. I'm an OT student and this has been drilled into me.
Do you mean flexion and (abd)uction?? If so, the prime mover would be the deltoid muscle with many smaller muscles assisting. If you are in fact meaning flexion and adduction, the prime mover would be the pectoralis major and the latissimus dorsi with many smaller muscles assisting.
