BY 115/115L. Basic Vocabulary. Agonist – performing the action. Antagonist – opposite of the agonist/performs opposite action. Synergist – assists the agonist. Insertion – more distal and lateral/joint where primary movement takes place. Nerve . Plexuses. Networks of successive . ventral. rami that exchange fibers (crisscross & redistribute). Why would this be protective?. Mainly innervate the limbs. Thoracic ventral rami do not form nerve plexuses. “Pain from the front of the knee”. Anatomy of the knee.
