The prime mover for shoulder flexion is the anterior deltoid muscle. This muscle is responsible for lifting the arm forward and upward at the shoulder joint.
The prime mover of flexion of the head is the sternocleidomastoid muscle. It acts to tilt and rotate the head to the opposite side when contracted unilaterally and both muscles together flex the neck and bring the head towards the chest.
The prime mover for knee flexion is the hamstring muscle group, including the biceps femoris, semitendinosus, and semimembranosus. These muscles originate from the ischial tuberosity in the pelvis and insert on the tibia and fibula, allowing them to flex the knee joint when contracting. Strengthening these muscles through exercises like hamstring curls can improve knee flexion strength and function.
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.
Synergist muscles are those that assist the prime mover muscle in a particular movement. For example, the biceps and brachialis are synergists in elbow flexion. Antagonist muscles are those that oppose the action of the prime mover, such as the triceps in elbow flexion.
The prime mover for shoulder flexion is the anterior deltoid muscle. This muscle is responsible for lifting the arm forward and upward at the shoulder joint.
Because shoulder horizontal adduction is performed when the arm is horizontal position (i.e., the elbow is level with shoulder) and adduction is movement toward the center of the body, shoulder horizontal adduction is performed primarily by pectoralis major and anterior deltoid, with an assist by latissimus dorsi.
Movement>prime mover. Abduction>deltoid. Adduction>gravity. Flexion>pectoralis major(sternal part). Extension>teres major. Medial rotation>pectoralis major(sternal). Lateral rotation>infraspinatus.
The deltoid is the prime mover in shoulder abduction. It's two antagonists are the pectoralis major and the latissimus dorsi.
prime mover (agonist)Not sure what you're asking here, but the biceps brachii is the prime mover facilitating flexion at the elbow joint.
Gastrocnemius
Pectoralis major

If a prime mover produces flexion, its antagonist will be the muscle responsible for producing extension at the same joint. They work in opposition to each other to create movement and stabilize the joint.
Tiil adidas is the prime mover of ankle plantar flexion.
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
your rectus abdominis is the prime mover in a crunch exercise or spinal flexion
