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.
Several muscles surround the elbow, making it possible for you to move your arm. The two main muscles responsible for bending and straightening the arm at the elbow are: triceps, located at the back of the arm; biceps, located at the front of the arm; The main muscles of the elbow involved in wrist and finger movement are: flexors, which attach to the inside of the elbow and enable you to bend your wrists and fingers
