Supinator. Also, as pronator teres also contributes to flexion of the elbow, that action is antagonized by the triceps.
The pronator teres and pronator quadratus
The antagonist for the supinator muscle is the pronator teres muscle. These muscles work in opposition to each other to produce rotation of the forearm.
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.
Pronator quadratus and pronator teres perform pronation, brachioradialis aids initiation of the movement.
Pronator quadratus and pronator teres
This is mostly achieved by the Pronator Teres and hte Pronator Qudratus muscles.
Pronator teres
The Pronator Teres muscle pronates the forearm at the radioulnar joint. It also provides flexion of the forearm at the elbow joint
pronates the forearm
Pronator teres
The most common treatment for pronator teres syndrome, which is often mis-diagnosed as carpal tunnel syndrome, is Neuromuscular Therapy or Trigger Point Therapy to eliminate myofascial trigger points in the pronator teres muscle, and its associated muscles and antagonists like the supinator.
