Best answer: What muscle is the synergist to the biceps Brachii?

What muscles are synergist?

During flexing of the forearm, the brachioradialis and brachialis act as synergist muscles, aiding the biceps brachii in pulling the forearm up towards the shoulder. The muscles of the rotator cuff are also synergists in that they fix the shoulder joint allowing the bicepps brachii to exert a greater force.

What does the biceps brachii muscle attach to?

Biceps brachii muscle

Origin Short head – Apex of the Coracoid process of the scapula Long head – Supraglenoid tubercle of the scapula Mnemonic: ‘You walk Shorter to a street Corner. You ride Longer on a Superhighway’
Insertion Radial tuberosity of the radius Deep fascia of forearm (insertion of the bicipital aponeurosis)

Which muscle is the prime mover of the elbow and a synergist of the bicep brachii?

Prime Movers and Synergists The biceps brachii flex the lower arm. The brachoradialis, in the forearm, and brachialis, located deep to the biceps in the upper arm, are both synergists that aid in this motion.

Is the brachialis a synergist?

To lift a cup, a muscle called the biceps brachii is actually the prime mover; however, because it can be assisted by the brachialis, the brachialis is called a synergist in this action (Figure 1). A synergist can also be a fixator that stabilizes the bone that is the attachment for the prime mover’s origin.

What is the synergist of elbow flexion?

Biceps brachii and brachioradialis act as synergists when producing an elbow flexion torque, but can be synergists or antagonists when exerting a torque about the pronation–supination axis of the forearm (Gielen and van Zuylen 1986; Buchanan et al.
