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.
prime mover (agonist)Not sure what you're asking here, but the biceps brachii is the prime mover facilitating flexion at the elbow joint.
Tiil adidas is the prime mover of ankle plantar flexion.
The Main muscles used when you do elbow curls are the bicep muscles.
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.
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.
Shoulder extension is controlled by: Long head of the triceps, the last, and the teres major
The prim mover for hip flexion is the Rectus femoris. This is a quadricep muscle that crosses the hip joint.
a prime mover is the main muscle that causes movement. In the case of the hip flexion, the prime mover would be the rectus femoris or the ilopsoas
Brachialis is the chief mover, aided by biceps brachii
