Nasal polyps are soft, painless growths inside the nasal passages. They often occur in the area where the upper sinuses drain into your nose (where your eyes, nose, and cheekbones meet). 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.
This is called antagonistic muscle action. The working muscle is called the prime mover or agonist. (it s in agony!) The relaxing muscle is the antagonist. The other main pair of muscle that work together are the quadriceps and hamstrings.The prime mover is helped by other muscles called synergists.These contract at the same time as the prime mover. They hold the body in position so that the prime mover can work smoothly.it s in agony!) The relaxing muscle is the antagonist.
