The synergist muscle is a kind of muscle that performs or helps perform the same set of joint motion as the agonists. Synergist muscle acts on movable joints.
The synergist to the smiling muscle (zygomaticus major) is the orbicularis oculi muscle, which is responsible for the contraction around the eyes and contributes to the overall expression of a smile.
The rectus femoris muscle is a synergist of the iliopsoas. It works together with the iliopsoas to flex the hip joint.
The gastrocnemius muscle is the synergist of plantar flexion of the foot. It works together with the soleus muscle to help push the foot downward and point the toes.
The synergist to the pectoralis major muscle is the deltoid muscle. The deltoid helps to assist in shoulder flexion and abduction, which complements the actions of the pectoralis major in movements like pushing or pressing exercises.
The biceps brachii muscle acts as a synergist for supination of the hand. It works in coordination with other muscles, such as the supinator muscle, to rotate the forearm and bring the palm facing upwards.
A synergist muscle is a muscle that aids another by promoting the same movement.
The muscle that aids the jaw in closing is the temporalis muscle. The masseter is the muscle that primarily moves the jaw.
The synergist to the smiling muscle (zygomaticus major) is the orbicularis oculi muscle, which is responsible for the contraction around the eyes and contributes to the overall expression of a smile.
Piriformis
The rectus femoris muscle is a synergist of the iliopsoas. It works together with the iliopsoas to flex the hip joint.
infraspinatus muscle
agonist, antagonist, synergist
Gastrocnemius
Latissimus dorsi is the synergist of the teres major.Specifically, a synergist is a muscle which acts with another. The latissimus dorsi helps adduct and rotate the shoulder to elbow bone called the humerus. The teres major is a shoulder-related muscle.
brachialis
Teres major
The muscle that aids the jaw in closing is the temporalis muscle. The masseter is the muscle that primarily moves the jaw.
