You may not even know that you have polyps because they lack nerve sensation. Polyps can grow large enough to block your nasal passages, resulting in chronic congestion. Symptoms can include:
During elbow flexion where the bicep is the agonist, the tricep muscle is the antagonist. While the agonist contracts causing the movement to occur, the antagonist typically relaxes so as not to impede the agonist, as seen in the image above.gonist: The agonist in a movement is the muscle(s) that provides the major force to complete the movement. Because of this agonists are known as the âprime moversâ. In the bicep curl which produces flexion at the elbow, the biceps muscle is the agonist, as seen in the image below.
In prolonged exhausting work, fat in the muscles can also be used for energy, and as a consequence the muscles become leaner. agonistic muscle one opposed in action by another muscle, the antagonistic muscle. Called also agonist. antagonistic muscle one that counteracts the action of another (the agonistic muscle).eltoid muscle the muscular cap of the shoulder, often used as a site for an intramuscular injection. See appendix 3-4. extraocular m's the six voluntary muscles that move the eyeball: superior, inferior, middle, and lateral recti, and superior and inferior oblique muscles.
