Cocaine can be detected in the urine for 4-8 hours after a single snorted (nasal) dose, and up to 24 hours after a single ingested (oral) dose. A breakdown product of cocaine, benzoylecgonine can be detected in the urine for up to 60 hours after a single use, or up to 22 days after repeated use.
1. Agonist: 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.
It can also slow down the movement of the agonist muscle to prevent tearing or overuse. An example is the biceps and triceps muscle group. When you do a biceps curl (see image above), the agonist muscle is the biceps, and the antagonist muscle is the triceps. Now this is where it can get tricky.
