Sternocleidomastoid and the Scalenes are Synergists, which mean that they work together to provide the same movements (flexion, rotation and lateral flexion of the head and neck)An Antagonist is a muscle that does the opposite movements. In this case, Antagonists of the Scalenes would be your posterior neck muscles, such as:Upper TrapeziusSplenius CapitusSplenius CervicisSemispinalis Capitis, etc
The flexor carpi radialis is the agonist muscle in wrist flexion. This muscle, know as a wrist flexor, is located in the forearm.
Tiil adidas is the prime mover of ankle plantar flexion.
Tibialis Posterior
The Pectoralis major (clavicular head), coracobrachialis, and biceps brachia are the synergists for shoulder flexion. For horizontal flexion, the Anterior deltoid is the synergist muscle.
aids in flexion of the head and the neck
shoulder
All muscles that are agonists or synergists in knee extention, are antagonists in knee flexion.
The antagonist for the brachioradialis muscle is the pronator teres. It helps to produce opposite movements at the elbow joint, with the brachioradialis mainly responsible for elbow flexion and the pronator teres for elbow extension.
Prime mover is the bicep and the antagonist is the tricep.
